With so many legendary stories surrounding it, what can we say about the GR20 that hasn’t been said already? We’re here to tell you that the legends are legit. The GR20 is all of those things and more. If you’re a passionate hiker, consider this trek to be your piece de resistance, your Superbowl, your ultimate adventure. Due to its challenging reputation, many hikers feel too intimidated to take on the GR20, and among those who do attempt it, a large percentage don’t complete it. Don’t let that be you!
With the right preparation, you can tackle the infamous GR20 and even (gasp!) have a ton of fun doing it. The key is having realistic expectations and doing some advance planning. Our guide will walk you through everything you need to know to prepare for this epic adventure. Trust us, it is so worth it.

About the GR20
The GR20* runs roughly north to south across the island of Corsica. Corsica is a semi-autonomous French territory located in the Mediterranean Sea. Sometimes referred to as the ‘Granite Isle,’ Corsica owes much of its beauty to its rich and diverse geologic history. This relatively small island boasts a wide array of spectacular natural scenery, including towering granite spires, lush wooded valleys, and turquoise rock pools.
* GR=”Grande Randonee,” a term for a collection of Europe’s greatest long-distance footpaths
How long is the GR20?
Distance: 180 km (112 miles)
Elevation gain: 10,000 meters (32,808 feet)
How long does it take to hike the GR20?
Typically 12-15 days, depending on fitness and pace. Many hikers may want to give themselves 16 days to allow for a rest day and flexibility in the case of inclement weather. Attempting to complete the entire route in less than 12 days is only recommended for the very hardcore hiker who is up for spending long days on the trail. It is important to keep in mind that the GR20 is different from many other hikes due to the amount of scrambling required. While you might have a good sense of your hiking pace on normal trails,those estimates tend to go out the window on the GR20.
Our advice? Give yourself more time than you think you need and don’t try to “double up” on stages. The trek is way more enjoyable (and still plenty challenging) when you’re not rushing through it or pushing your limits too far. That said, when we were hiking, we met a superhuman who was trying to do the entire thing in five days. Different strokes for different folks I guess!
I only have time to do half…should I hike the North or South?
The GR20 is neatly divided into two sections, the northern (“nord”) and southern (“sud”), with the town of Vizzavona at the midpoint. This makes it relatively easy to hop on or off the trail at Vizzavona in order to only hike one half. If you have to choose, take comfort in the fact that the GR20 is truly spectacular from start to finish and you can’t go wrong with either section!
In our opinion, the north has the most rugged and beautiful mountain scenery and it’s more fun and interesting to hike. The trade-off, however, is that it also entails the most scrambling and greater sections of trail that are steep and technical. The south is a bit mellower, but it definitely isn’t easy. There are still plenty of tough climbs and parts that require scrambling. If you choose to only hike the southern half, you’ll still get some beautiful mountain views, but you’ll also spend a good amount of time down in the forests and valleys.
How difficult is the GR20?
There’s no doubt about it- the GR20 is a challenging trek. Some of the major factors that contribute to its difficulty are the large amount of scrambling, steep ascents and descents, overall distance, heat and weather, and exposed nature of the trail. We believe that most reasonably fit people can complete the GR20, but that doesn’t necessarily mean that they should. You’re much, much more likely to actually enjoy it if you are in good hiking shape and have backpacking experience. Most of the scrambling is pretty manageable; it is just tricky and awkward at times and can become tiring after you’ve been at it for awhile. If you are judicious about avoiding storms and careful on exposed sections, it really isn’t much more dangerous than other hikes.
Our top tips for making the GR20 less challenging:
1. Carry the lightest backpack possible.
2. Only hike one stage per day. Don’t try to double-up stages and take on more than necessary. Give your body time to recover in the afternoon rather than spending 8+ hours on the trail every day.
3. Start early! High temperatures increase your effort level significantly. Avoid the worst of the afternoon heat (and storms) by getting on the trail at sunrise.
These three simple things can absolutely be the difference-maker in terms of whether or not you complete the trek (and do so without hating every second of it).
When to Hike the GR20
The typical hiking season for the GR20 lasts from June through September. It may be possible to hike in the later part of May, but you’ll need to be prepared for snow and ice on the trail.
- If hiking in May, the refuges will be open but not staffed, meaning that you’ll need to bring all of your own food and fuel.
- Beginning in June, the refuges will be staffed and supplied, but you may still need to negotiate some sections of snow and ice along the trail. The weather in June will be warm, but not too hot.
- July and August are the most popular months for hiking the GR20. All of the services (accommodation, busses, etc) will be fully operating and the trail should be clear of snow. Expect very hot weather and afternoon thunderstorms.
- September brings cooler temperatures and fewer crowds. The refuges remain staffed through the end of the month, but the bus services are reduced and some of the bergeries start to close.
- Hiking is possible in October, but the refuges will not be staffed (they will remain open) and snow is likely from mid-October onwards.
May and October are the least crowded times on the trail. June and September are quieter than the peak season, but still quite busy. The trail is the most crowded in July and August. We recommend making advance reservations for all accommodation (unless carrying your own tent) if you’re planning on trekking anytime between June and September.
Mountain weather is always volatile, and the GR20 is no different. However, the GR20 is rather unique in the sense that the trail stays high up on exposed ridges for long stretches, making it more important than ever for hikers to be vigilant about the conditions. Getting caught high up in the mountains during a storm is extremely dangerous, but you can greatly minimize your risk by taking a few important precautions.
- Always ask the wardens at the refuge for the latest weather forecast and heed their advice.
- The Meteoblue App is arguably the best resource for checking the weather. It allows you to see the forecast for specific peaks or coordinates, plus it has excellent radar displays and wind predictions. Check it every time you have cell service.
- Start hiking early in the day! Not only will you enjoy gorgeous sunrises, get to camp before the crowds, and avoid the heat, but you’ll also greatly reduce your risk of getting caught in afternoon thunderstorms.
The traditional GR20 route starts in Calenzana in the north, passes through the midpoint in Vizzavona, and finishes in Conca in the south. However, it is possible to hike in either direction. The northern half of the GR20 has a reputation for being the toughest, while the southern half is a bit gentler. Some trekkers prefer to start in the south to get accustomed to the trail before tackling the tougher sections in the north. Others would rather start in the north in order to put the biggest days behind them early and do so with fresh legs.
It is totally a matter of personal preference, although we hiked from north to south and would definitely recommend it. We benefited from the confidence boost that came with conquering the most challenging sections early on, and we felt the ascents and descents were more manageable in this direction. While slightly less people hike in the northbound direction, you probably won’t notice a significant difference in crowds since hikers headed both ways stay at the same refuges.
Food and Drink
As we’ve mentioned before (and certainly will remind you about again!), keeping your backpack as light as possible is essential for having a successful GR20 trek. Fortunately, you don’t need to carry much food, which will significantly reduce your pack weight. Food can be purchased at all of the refuges along the route. However, there is a lot of variation in terms of what’s available at any given refuge on any given day. It’s not cheap, but it doesn’t have to be super expensive either, providing that you cook your own meals. On the other hand, if you order meals at the refuges, expect to pay upwards of €20 for a glorified bowl of pasta.
Most refuges on the GR20 also have small shops where you can get basics like bread, pasta, sauce, canned fish, canned meals, chocolate, and biscuits. All of the refuges also serve dinner and breakfast, and some offer a-la-carte meals throughout the day as well. Beer, wine, soda, coffee, and tea are sold everywhere. There are no grocery stores along the GR20. The closest you’ll get to a supermarket are the larger, better-stocked shops available at a few refuges and campgrounds along the route. We’ve noted the locations of these within the guide. On the trail between the refuges, there generally isn’t anywhere to purchase food, save for the rare exception of a bergerie selling cheese and charcuterie.
The GR20 is not very accommodating to those with special diets. Vegetarians will be alright, provided they are okay with eating pasta for dinner every night and consuming large amounts of cheese and bread. We recommend carrying at least one “backup” meal in case you can’t find veg-friendly food at a refuge. Those who are vegan or gluten-free should plan on bringing most of their own food, as their options will be very limited.
Nearly every accommodation along the route provides a cooking area that is free to use for all who are staying there, campers included. All of these cooking areas have a gas-powered cooktops, many have pots/pans, and some have dishes and cutlery. It isn’t necessary to bring your own stove and fuel, but many people choose to do so, as the cooking areas can get crowded. If planning to self-cater regularly, you’ll probably want to bring your own pot and bowl/utensils, since those aren’t provided at most places. Also, you’ll need to bring your own lighter to ignite the stoves.
All of the refuges provide potable water (usually from a tap labeled “source”). It is generally safe to drink, and most hikers choose to do so without filtration. There are some water sources along the trail, but they are not always at regular intervals, they’re not on every stage, and many are season-dependent. Some of these require filtration, due to the proximity of livestock (Corsican cows are amazing hikers and you’ll see them in shockingly high places!) Our advice would be to fill up at the refuges before setting out and carry enough water for the entire day (2-4 liters, depending on stage length, heat, and personal preference).
You’ll have a range of lodging options along the GR20, although most will be at the PNRC-run refuges and nearly all will be “rustic” at best. We’ve outlined what you can expect from each option below.
If you prefer not to camp along the GR20, you’ll spend most of your nights in the park-run mountain huts (or refuges). These offer basic, dorm-style accommodation. Beds are provided, but you’ll need your own sleeping bag and pillow. All offer an evening meal and basic breakfast for an additional charge. The refuges vary in terms of their amenities; some refuges have hot showers, proper toilets, and electronics charging, while others have only a couple of cold showers and squat toilets. Refuges can be reserved through this website.
In addition to the PNRC Refuges, there are some privately-owned bergeries along the GR20. These are quite similar to the refuges in that they offer basic dorm-style accommodation and the option for half-pension (dinner and breakfast).
There are a few opportunities to stay in hotels while hiking the GR20, typically these opportunities arise when the trail brings you closer to civilization. These hotels offer the typical amenities you’d expect from this level of lodging, such as hot showers, private bathrooms, bedding and towels, and WiFi.
Renting a tent
Many GR20 hikers choose to stay in the “hire tents” that are available for rent at all of the refuges and most bergeries. This option costs less than sleeping in dorms, but more than camping with your own tent. Hire tents are typically the Quechua pop-up style for two or three people, and include a sleeping pad or mattress. They offer a good option for those who want the perks of camping (more privacy, less risk of bedbugs) without having to carry all of the gear. While you can reserve a place in a hire tent ahead of time, you cannot reserve a specific tent. The tents vary quite a bit in terms of location within the camping area, levelness of the pitch, and general niceness. Get there early to have your pick of the best tents.
Carrying a tent
Carrying your own tent will cost you the least and give you the most flexibility. Wild camping is forbidden on the GR20 (with the exception of one designated spot between Refuges d’Usciolu and Refuge d’Asinau). However, you can pitch your tent outside all of the refuges along the route, and most of the bergeries and gites allow camping as well. Campers have access to all of the facilities at the refuges, including the toilets, showers, cooking areas, and meals. Carrying your own tent is the only accommodation option that does not require advance reservations. That being said, in the busy season you’ll still want to arrive at the campground early to snag a good spot. All of the camping pitches are definitely not created equal! Many pitches are uneven, rocky, and quite far from the facilities, and the campgrounds can get very full by about 4:00pm. If you’re considering carrying a tent, you’ll want to carefully weigh the benefits of added comfort and flexibility versus the added weight in your pack.
A few other things you should know about GR20 accommodation:
The GR20 is an extremely popular trail with limited accommodation options. Unless you are hiking very early or very late in the season, you can expect the refuges and campgrounds to be full at every stage of your hike. Hikers with their own tent do not need reservations (and we wouldn’t recommend making them), but all others-those using hire tents, those staying in dorms, and those staying in hotels- must make advance bookings.
Bookings can be made online at http://reserver.sitecresa.fr/centraleresa/parcnaturel and need to be paid in full to be confirmed. Wardens at the refuges expect you to print your reservation and present it upon arrival. If you need to change your reservation, you’ll need to call or email the PNRC using the information provided on your booking receipt. Reservations can be cancelled within 15 days of the initial booking date for a full refund.
Other Important Information:
–You need to provide your own toilet paper. Some refuges sell it, but it is not available everywhere. It pays to be prepared!
-Toilets, showers, and dormitories are almost always mixed gender.
–Bedbugs are a common problem in the refuges. Bring bedbug spray and be vigilant.
Corsica is known for a lot of great things, such as its mountains and beaches, but not necessarily for its well-connected, timely, easy-to-navigate transportation system. However, it is certainly possible to get to and from the GR20 without too many headaches, provided that you plan ahead and give yourself enough time. Check out our logistics article for all of the details.
The GR20 is extremely well-marked with red and white paint flashes every 20 feet or so. Keep a close eye out for markers, as sometimes the trail heads in seemingly improbable directions! The markers show you the easiest way up or down, so follow them closely, especially when scrambling. If you choose to take one of the many alternate route options, you can expect these trails to be less well-marked. We recommend carrying a map at all times and using a GPS.
Money on the GR20
The most important thing you need to know here is that the GR20 is pretty much a cash-only economy. There are no ATMs along the route, not even in Calenzana and Conca at the endpoints, nor in Vizzavona at the midpoint. Therefore, it will be essential for you to estimate your expected daily costs (food and lodging), plus some cushion for transportation and other miscellaneous or unplanned items. Multiply your daily costs by how long you plan to be on the trail, again factoring in some cushion for rest days, bad weather, and your time in Calenzana and Conca. If you make reservations for refuges or hire tents, you will have paid in full for this accommodation ahead of time and won’t need to carry quite as much money.
A small number of places accept credit cards, (such as the campground shop in Vizzavona and many of the hotels) and you might be lucky enough to get cash back in a pinch. In general, things are relatively expensive in Corsica, especially along the trail. Check out our How Much It Cost Us to Hike the GR20 article for more on what you can expect to pay.
What to Pack for the GR20
Deciding what to pack (and not pack) for the GR20 is one of the most crucial steps in preparing for a successful trek. The trail demands that you pull yourself up chains on sheer rock faces, squeeze through awkward gullies, and ascend and descend endless scree slopes. Trust us, this is hard enough without a big, bulky backpack throwing off your center of balance and increasing your overall exertion…no need to make it any harder than it has to be! The good news is, with a little strategic planning you can minimize your pack size while still having everything you need, and you don’t need to go out and buy all of the fanciest lightweight gear to do so.
A few of our top tips:
- Only carry 1-2 days’ worth of food, since provisions can be purchased at every refuge.
- Unless you are a passionate photographer, leave your bulky camera at home. Most smartphones take excellent pictures. Plus, you won’t have many chances to recharge a camera battery.
- Only pack clothes that you absolutely need. Two shirts will be plenty, as you can rinse them out and dry them in the sun quite easily.
- You can cook at the refuges, so you don’t need to carry much stove fuel (if any).
- Bring trekking poles. They are invaluable on many of the steeper sections.
- Many hotels will let you store extra luggage if you have an upcoming reservation with them.
- Either hiking boots or trail runners will work, just make sure they are comfortable and supportive. They should be broken in a little, but otherwise fairly new (the gnarly GR20 trail conditions put a lot of wear and tear on shoes).
Some of the refuges and other accommodations along the GR20 will allow you to charge your electronics, but there is a lot of variation from place to place. Many refuges require a small payment for charging (typically €2) and will only allow you to charge your phone (not your smartwatch, camera, etc). Others will do it for free and allow you unlimited access to plug in whatever you want. Still others only provide charging during a set time in the afternoon, due to the fact that they rely on solar. We’ve noted the availability of device charging within each stage of this guide. If you plan on using your phone for navigation, we strongly recommend bringing a battery backup or portable solar panel.
Cell Phone Service
Cell phone service is unreliable along the GR20. You might get signal at the high points on the trail and at some of the accommodations that are close to a road or town. WiFi is even less common; you’re only likely to find it at a few of the fancier hotels along the route.
A Stage-by-Stage Guide
Below you’ll find a brief description of every stage of the GR20 in terms of the accommodation options and services you can expect to find there. This guide is written for the typical north to south direction, but could easily be reversed.
Prices for accommodation at the PNRC Refuges are as follows:
- Dorm Bed: €15 per person
- Hire Tent: €11 per tent, plus €7 per person
- Camping (bivouac) in personal tent: €7 per person
These prices are the same at every PNRC refuge, and therefore we haven’t listed prices for each individual refuge. For all other accommodations, prices have been noted in the guide whenever possible or links are provided fo r the most up-to-date information.
Stage Zero: Calenzana
We strongly recommend that you stay in Calenzana the night before starting your hike, as it’s essential to get an early start on stage one. Calenzana is a pretty town with a good range of accommodation options and services available. If you absolutely don’t want to spend a night in Calenzana, you could stay in Calvi and arrange an early taxi to the trailhead the next morning.
Accommodation in Calenzana:
- Dorm beds and camping are available at the Gite d’Etape Communal on the edge of town. Contact them at 04 95 62 77 13 or email@example.com for reservations and prices.
- Hotel Bel Horizon and the Chambres d’Hote L’Ombre du Clocher offer hotel accommodation in a more central location. Expect to pay around €150 for a room at either hotel.
- There are also a few AirBnBs available in town which offer nice apartments for a reasonable price.
Services in Calenzana
There is a Spar Supermarket in town which sells a wide range of items, including stove fuel. A bus operated by Beaux Voyages which runs between Calenzana and Calvi, although it’s pretty infrequent (once or twice daily, depending on the time of year). There are several restaurants and bars in town offering everything from casual pizzas to hearty Corsican fare. A post office is located in the center of the village. Keep in mind that there is no ATM in Calenzana.
Stage One: Calenzana to Refuge d’Ortu di u Piobbu
In his Cicerone Guide, author Paddy Dillon describes this first stage of the GR20 as a “baptism of fire” Personally, we think this is a little dramatic, but it’s certainly no cakewalk. Regardless of how tough your first day on the trail feels, you’ll be thrilled to get to Refuge d’Ortu di u Piobbu. With its friendly warden and sweeping sea views, it is the perfect introduction to your GR20 experience. When we hiked in 2019 the refuge building had recently burned down, but they were still providing a wide range of services and accommodation was available in hire tents (no dormitory though). There are many good, flat campsites available, most of which are on hard-packed dirt.
Hire tents, camping, warm(ish) showers, composting toilets, sinks, potable water available from a spring a few hundred yards down the trail, a small shop, a-la-carte food items (omelettes, charcuterie, sandwiches, etc) available until dinnertime, electronics charging possible (ask the warden), cell phone service, picnic tables.
Stage Two: Refuge d’Ortu di u Piobbu to Refuge de Carozzu
PNRC Refuge de Carozzu is tucked into the woods in a way that gives it summer camp vibes. The refuge has a dormitory with 36 beds, as well as a kitchen and dining room. There are camping pitches in an open area next to the refuge, as well as dotted in the surrounding trees in every direction from the refuge. Keep in mind that the campground can get very crowded, making it difficult to find a good spot. The warden doesn’t arrive until 3:00pm, so if you get there earlier you can pitch your tent (or grab a hire tent) and pay later. There is a lovely terrace in front of the refuge with lots of picnic tables for enjoying the amazing views down the forested valley.
Dormitory, hire tents, camping, composting toilets, cold showers (available after 3pm), potable water, shop with very limited offerings, a-la-carte food items available all day, indoor kitchen, outdoor cooking area, sinks, clotheslines, picnic tables.
Stage Three: Refuge de Carozzu to Ascu Stagnu
Many hikers approach stage three with a sense of trepidation, as the trail requires the crossing of the Spasimata Slabs (nicknamed the “slabs of doom” by some hikers). These large, tilted rock slabs are set in a dramatic gorge, and they are fitted with chains and cables to aid crossing in some places. You can relax though; in dry conditions, especially when traveling uphill, they really aren’t scary at all and the surrounding gorge is seriously beautiful!
In any case, you’ll have earned a bit of luxury by the end of stage three, and that’s what you’ll get when you reach the Ascu Stagnu ski area (also known as Haute Asco). What it lacks in prettiness, it makes up for in services. In addition to the 32 dorm beds in the PNRC refuge, hikers can also stay in the Hotel le Chalet (€100 for a double room) or in a dorm bed in the hotel-run gite d’etape (€45 for half pension). Campers will have tons of good pitches to choose from. If camping, you can pay at the PNRC refuge and use its facilities.
All of the accommodation options offer indoor flush toilets, sinks with hot water, hot showers, and electronics charging. The refuge has a well-stocked shop, provides meals, and sells snacks, drinks, and charcuterie. It has a nice indoor kitchen with a wide assortment of pots, pans, dishes, and cutlery available, plus a large indoor dining room and some outdoor terrace seating. The refuge also has an outdoor cooking area and clothesline. There is a casual snack bar across the parking lot from the refuge which sells hot meals, drinks, and ice cream. There’s also a fancier restaurant and bar attached to the hotel. Transportation to the town Ponte Leccia can be arranged and laundry services are also available.
Stage Four: Ascu Stagnu to Auberge U Vallone or Refuge de Tighjettu
You’ll have two choices for your accommodation on stage four. The first option you’ll come across is the PNRC Refuge de Tighjettu, located on a hillside with big valley views. This is a good option if you want to stop a bit earlier (this stage is one of the longest and most difficult of the entire trek) or if you like the predictability of the PNRC Refuges. Tighjettu is also a bit less expensive than your other option, the Auberge U Vallone. If you continue another 30 minutes on the trail past Tighjettu, you’ll reach the privately-run Auberge. In all honesty, the place is a little odd, but the gorgeous views from the terrace, easy access to perfect rock pools, and piping hot showers more than compensate for its quirks.
Services at Tighjettu:
Dorm beds, hire tents,camping, showers (sometimes warm), toilets, indoor kitchen and dining area, potable water, small shop, meals, sinks.
Services at Vallone:
Hire tents and camping. Hot showers, flush toilets, terrace, potable water, electronics charging, very limited shop, restaurant, camping and hire tents available. There is no cooking area here, and camping costs €8.5o per person (if carrying your own tent). Reservations for hire tents can be made on their website.
Stage Five: Auberge U Vallone to Hotel Castel di Vergio
The Hotel Castel di Vergio is another example of a stop along the GR20 that you might just fall in love with, certainly not because of the natural beauty of its surroundings (there’s not much of that), but because of the little luxuries you’ll enjoy there. Due to its roadside location, the hotel shop is one of the best along the entire GR20 route, stocked with everything from duct tape and batteries to fresh produce and warm bread. The camping area is one of the few along the route that has nice soft grass (instead of hard packed dirt) on which to pitch one’s tent. It’s the little things in life, right?
Hot showers, electronics charging, cell service, flush toilets, sinks, potable water (available from the cooking area sink), well-stocked shop, and a bar and restaurant located in the nearby hotel. Camping (€7 per person) is available for those with their own tents, but there are no hire tents for rent. Lodging is available in the hotel (€100 for a double room) or in dorms in the gite (€20 per person). Both campers and those staying in the gite have the option for half pension. A complete list of prices and booking information can be found here.
Stage Six: Hotel Castel di Vergio to Refuge de Manganu
After the challenges of the first five stages, stage six is a welcome and relaxing change of pace. The hiking is capped off perfectly by a stay at the PNRC Refuge du Manganu. This small refuge is located on a scenic rocky outcrop and enjoys tranquil views of the valley below. There is a dorm with 21 beds, plus many hire tents and camping pitches scattered around the refuge. Despite its sprawling size, it can still get quite crowded and lines for the sinks and toilets are pretty common. Manganu has a fun and lively atmosphere- hikers gather on the rocks to drink beers and enjoy the views or to take a dip in the picture perfect rock pool below the refuge.
Dorm beds, hire tents, camping, composting toilets, sinks, potable water, electronics charging (€2), hot showers (€2 for six minutes), outdoor cooking area, a-la-carte snacks available all day, meals, and a shop with limited provisions for sale.
Stage Seven: Refuge de Manganu to Refuge Petra Piana
PNRC Refuge Petra Piana gets a bad rep for its cold, cloudy, inhospitable location. In fact, many trekkers choose to double-up on stages and continue all the way to Refuge L’Onda in order to avoid staying at Petra Piana. It’s true that Petra Piana is often shrouded in layer of chilly fog, but it’s a charming spot nonetheless. The tiny refuge houses a small dorm and a cozy kitchen with a couple of picnic tables where hikers can gather to enjoy the warmth and camaraderie. If you decide to keep hiking instead of stopping at Petra Piana, be aware that there is no lodging available until you reach Refuge de l’Onda. Many trekkers mistakenly think they can stay at one of the bergeries along the way to L’Onda and end up setting themselves up for a much longer day than they anticipated.
Dormitory, hire tents, camping, squat toilets, sink, hot showers (€2 for six minutes), meals, small shop, well-stocked indoor kitchen, and potable water. No electronics charging. Credit cards may be accepted here.
Stage Eight: Refuge de Petra Piana to Refuge L’Onda
The setting for Refuge L’Onda couldn’t be more different than that of Petra Piana. Instead of the high, misty mountain top location of the previous stage, L’Onda sits down in a sunny, pastoral valley. There is a PNRC refuge up the hill, but most hikers choose to camp down in the valley next to the Bergeries L’Onda. In fact, unless you took the high-level variant to get there, you probably won’t even get close to the actual refuge. If you do intend to stay in the refuge, make sure to inquire ahead of time as it isn’t always open. If camping, hire tents are available, as well as grassy (though not super flat) pitches for those with their own tents. While you are technically camping at the bergeries, everything runs the same as at the PNRC campsites and prices are identical. Insider tip: though not immediately obvious, there are some lovely rock pools nearby, perfect for cooling off after a hot day on the trail!
The campsite next to the Bergeries has squat toilets, sinks, a cooking area with pots, pans, and dishware, showers (€2 for hot water, free if cold), lots of picnic tables, and a clothesline. The bergeries sells a la carte items all day, plus meals, and it offers a decent selection of provisions at its shop. The refuge has a small dormitory, kitchen, toilets, and showers.
Stage Nine: Refuge L’Onda to Vizzavona
This is an exciting stage! In reaching Vizzavona, you’ll be marking the halfway point of the GR20. Better yet, you’ll get to celebrate this achievement with all of the luxuries that Vizzavona has to offer. In reality, Vizzanona is a tiny town with just a few hotels, restaurants, and a train station, but it is nevertheless a great place to spend the night or even take a rest day if you have the time. There is a range of accommodation available, from dirtbag to deluxe, but all options offer hot showers and electronics charging (things you’ll want at this point in the trek, trust us). With the exception of the campground, most places also provide WiFi, and many of the hotels offer a laundry service.
Hire tents, pitches, and dorm beds in a small gite are available at the L’Alzarella campsite on the edge of town. This campground has electronics charging, hot showers (€2.50), clothesline, sinks, toilets, a cooking area, and probably the best stocked shop on the entire GR20. It also accepts credit cards. The campground doesn’t take advance bookings, except for large groups. Camping costs €7.50 per person for campers with their own tents.
If you want to sleep indoors without spending a fortune, you have a couple of dorm-style accommodations to choose from. There is a refuge at the Bar Restaurant de la Gare, as well as at the Hotel Restaurant I Laricci (no website available). Expect to pay around €20 for either of these options.
For a little bit of luxury, we recommend staying at the Casa Alta B&B. The friendly owners go out of their way to make your stay special, the wooded setting is tranquil and beautiful, and the breakfast is ridiculously good. Another upscale option is the Hotel U Castellu.
There is also more lodging available in La Foce, which can be accessed by taking a shortcut before reaching Vizzavona.
Stage 10: Vizzavona to Bergeries d’E Capanelle
There are a few options for accommodation at this stage of the trek, although it can be a little tricky to figure out what they are. Upon arriving from the north, you’ll first come across the Gite d’Etape U Fagone (which also calls itself the Gite de Capanelle). This is the most convenient and popular place to spend the night. There are beds available in small chalets and large dormitories, plus hire tents and pitches available (although space is very limited).
Just above the gite, you’ll find the very small, very basic PNRC Refuge d’E Capanelle. This unstaffed refuge costs less than the other PNRC refuges, and can be paid for in the gite. Our guidebook said that free camping is permitted outside the refuge, but we found that to be false when we stayed there. All campers were required to pay at the gite. You can also travel up the road to reach the Gite d’Etape U Renosu, which has a few small dormitories and a camping area.
Services at Gite d’Etape U Fagone:
Hot showers, flush toilets, sinks, potable water, clothesline, restaurant serving al-la-carte items all day, meals, well-stocked shop, washing room, cell service, shady terrace with sea views. It costs €7 per person for camping, €10 per person for a hire tent, and €39 per person for half-pension in the gite. Reservations can be made on their website.
Services at Refuge d’E Capanelle:
Basic cooking area, picnic table, bunk beds. You’ll need to walk down to the gite to access toilets, water, and showers. Those camping outside the gite can use the cooking facilities in the refuge.
Services at Gite d’Etape U Renosu:
Toilets, hot showers, potable water, restaurant, small shop, and cell phone service. It’s €7 per person for camping and €38 per person for half-pension in the gite. Reservations can be made at +33 6 77 06 25 17.
Stage Eleven: E’Capanelle to Bocca di Verdi or Refuge de Prati
You’ll need to choose between two different accommodations at the end of stage eleven. There are a few factors to consider when deciding where to spend the night. First, it will depend on whether you take the classic low-level route on stage eleven or if you decide to tackle the high-level variant and the ascent of Monte Renosu. The high-level route is much longer and more challenging than the rather mellow low-level route. Therefore, if you took the classic low-level path on stage eleven, you might want to keep going past Bocca di Verdi to reach Refuge de Prati (another two hours uphill) to get a head start on the long day that awaits you on stage twelve.
Alternatively, if you took the high-level route, you will likely be more than ready to stop at Refuge Bocca di Verdi (Also known as Relais San Petru di Verde) rather than face another two hours of tough climbing after an already long and strenuous day. The other factor to consider is the nature of the facilities at each accommodation option. Refuge de Prati is a PNRC Refuge. Therefore, you can expect basic facilities and the usual prices. On the other hand, Bocca di Verdi is privately-run and provides much nicer facilities at a slightly higher cost (€8 per person for camping).
Services at Refuge de Prati:
Dormitory, large camping area with grassy pitches, hire tents, squat toilets, basic cold shower, meals, very limited shop, potable water.
Services at Bocca di Verdi:
Flush toilets (with toilet paper provided- a rare sight on the GR20!), hot showers, restaurant, meals, picnic tables, sinks, clothesline, potable water, small shop, cell phone service. Campers can use the kitchen in the main refuge building. Camping costs €8 per person and it’s about €40 per person for half-pension in the refuge. Beware of the aggressive pigs that wander the campsite in search of food! More information can be found on their website.
Stage Twelve: Bocca di Verdi or Refuge de Prati to Refuge d’Usciolu
Those who claim the entire southern half of the GR20 is “easy” obviously haven’t completed stage twelve. Make no mistake, it is a big day and it’s even bigger if you started at Bocca di Verdi! Don’t worry though, you’ll have a real treat awaiting you at the PNRC Refuge d’Usciolu. This refuge and its charismatic warden are GR20 legends, and rightfully so. The shop is downright magical, offering a dazzling array of provisions and tasty treats from a tiny shack. The refuge itself boasts an equally magical setting, perched impossibly on a rocky hillside. The only downside of such a setting for campers is that they’ll find themselves hiking a long way up and down that steep rocky hillside to get from their tent pitch to the refuge and its facilities.
Dormitory, hire tents, camping pitches, composting toilets, cold showers, sinks for washing up, potable water, clothesline, outdoor cooking area, terrace with picnic tables, restaurant serving a-la-carte items, meals, amazing shop, electronics charging (ask the warden).
Stage Thirteen: Refuge d’Usciolu to Refuge de Matalza or Bergerie d’ I Croci
Here’s another stage where hikers will yet again be faced with several choices. The official GR20 route is broken up into two stages before it reaches Refuge d’Asinau, with Matalza as the first stopping point and Refuge d’Asinau on the following day. However, for those moving at a faster pace it’s possible to take an alternate trail directly from Refuge d’Usciolu to Refuge d’Asinau, effectively cutting out an entire day of hiking. If you opt to stick to the traditional path, you’ll still come across three options for accommodation. First, you’ll pass the Bergeries de Basetta. Keep in mind that if you choose to stop here, you’re in for a very short day with a significantly longer one the following day. Next, you’ll pass the PNRC Refuge de Matalza, which offers a small dorm and camping area. It doesn’t boast the high mountain vistas of some GR20 refuges, but the friendly warden and peaceful pastoral setting more than make up for it. Finally, if you walk another hour along the trail, you’ll reach the privately-owned Bergerie d’ I Croci. The benefits of pushing on to I Croci are the slightly more luxurious accommodations and head start the following day.
Services at Bergeries de Basetta:
Cabins, dormitory/dortoir, camping pitches, hire tents, well-stocked shop, restaurant, and transport off-trail. Camping is €10 for two people with their own tent, half pension in the dortoir is €38.50 per person, and it’s €43.50 per person for half-pension in a cabin. Reservations can be made at 06.27.25.95.33 o4 firstname.lastname@example.org
Services at Refuge de Matalza:
Dormitory, hire tents, camping pitches, toilets, sink, potable water, clothesline, lounge chairs, shady terrace, warm showers (much nicer than they look!), decent shop offerings, electronics charging for a set time period in the afternoon, and a cooking area.
Services at Bergerie d’ I Croci:
Dormitories, camping pitches, toilets, hot showers, potable water, restaurant, small shop, meals, transport to the town of Zicavo. Camping is €6 per person, and it costs €10 per person for a bed in the dormitory. Reservations can be made by calling 06 75 49 60 59 and 09 82 12 33 10 and more information is available on their website.
Stage Fourteen: Refuge de Matalza to Refuge d’Asinau
After being destroyed by a fire a few years back, PNRC Refuge d’Asinau has recently been rebuilt and it’s quite cozy and tidy inside. It has a small dormitory, with space for camping both on the hillside behind the refuge and down below the front of the refuge (many people don’t realize there are pitches down there so you might score something really good!). This is another one of those places where your hiking never really ends for the day, as there’s a long, stony walk to get to the bathrooms and showers. Views from the terrace are wonderful.
Dormitory, hire tents, camping pitches, composting toilets, potable water, cold showers, very limited shop, meals, electronics charging (€2).
Stage Fifteen: Refuge d’Asinau to Village de Bavella or Refuge d’I Paliri
Stage fifteen officially ends at Village de Bavella, but if you’re camping, or if you want one last night at a (very beautiful!) PNRC Refuge, or if you want to get a head start on long final stage to Conca, you should keep hiking for about two more hours to the PNRC Refuge d’I Paliri. On the other hand, if you want to spend your last night on the GR20 in a more luxurious fashion, you’ll have your pick of gites and restaurants at Village de Bavella. It’s your final trail decision… it’s Conca or bust tomorrow!
Services at Village de Bavella:
Dorm beds are available either at Les Aiguilles de Bavella (€34 for half pension) or the Auberge du Col de Bavella (€45 for half pension). Both of these establishments also have restaurants. There is a well-stocked shop across the road from the Auberge du Col de Bavella. Bus and taxi services can be accessed from Village de Bavella.
Services at Refuge d’I Paliri:
Small dormitories, hire tents, camping pitches, squat toilets, showers (cold, very basic, and a loooong hike from camp-not recommended!), potable water (also need to hike down the trail for this), stunning views of rugged mountains and the sea in the distance, sinks, indoor and outdoor cooking areas, small shop, meals, and electronics charging (€2).
Stage Sixteen: Village de Bavella or Refuge d’I Paliri to Conca
You did it! Upon reaching Conca, we sincerely hope you beeline to the first establishment that will sell you a cold beer (FYI-that place is called Bar le Soleil Levant) and toast to your amazing accomplishment. The GR20 is a seriously challenging hike, both mentally and physically, and those who complete it have really achieved something special. Once you’ve enjoyed a celebratory cold one with your fellow badass hikers, you’ll need to think about moving on. If you want to leave Conca that same day, the Bar le Soleil Levant and the Gite d’Etape La Tonnelle offer shuttle services to Sainte Lucie de Porto Vecchio, where you can catch buses to Bastia, Ajaccio, or Porto Vecchio. You may be able to arrange direct service to Porto Vecchio (instead of transferring at Sainte Lucie) as well.
If you want to spend the night in Conca, we think that you’ll find it to be quite a nice little town. You can either stay at the more upscale Hotel San Pasquale (around €90 for a double room) or the budget-friendly Gite d’Etape La Tonnelle, which has rooms for 2-5 people and a 7-person dorm (€40 per person for half-pension),and camping (€7 per person). Hire tents are also available for €14 per person.
Services at Conca:
Both the Hotel and Gite have restaurants. There are two small shops in town, as well as a post office. The gite and the hotel also offer a laundry service. You can arrange transport to Sainte Lucie de Porto Vecchio through the gite.
