√ Hiking guide
We will provide walking notes describing the walking distance of each stage, altitude differences, the accommodation, and highlights along the way.

Half-board is not included in the price of this trek. You can get something to eat at the mountain huts along the way or you can get food from the towns below the trail. If you want to have a warm dinner at the hut, remember to ask for it as soon as you get to the hut.

The mountain huts along the GR20 offer basic accommodation and food. These refuges come under the regional Corsican natural park’s authority and can host 25-50 people depending on the hut. Hosts manage the huts from the end of May to early October. Outside of this time frame, the refuges are open but not manned and there is no food available. The refuges usually have one large dormitory with long wooden bunk beds equipped with mattresses. You can also sleep in a tent near the refuges. You can rent a tent at the hut as well. It is forbidden to camp in other places along the trail. Independent of which accommodation type you choose, you must always bring your own sleeping bag. Huts do have electricity. However, charging your phone or camera can be quite a challenge given the number of trekkers and the limited number of sockets. Make sure to carry extra batteries with you. You will spend the last night of the trek at a hotel in Bergeries de Capannelle in a shared dormitory.

What to expect in the huts:

- Indoor kitchen and eating area
- Dormitory room with bunk beds
- The bunk beds have two levels and have mattresses side by side. Bring your own sleeping bag
- Cold outdoor showers and toilets 
- An outdoor kitchen with cooking facilities
- Bins for rubbish

What is the food like in the huts?

Half board is not included when you book your accommodation. You can choose to carry food with you or you can get your meals at the huts. You can always find a freshwater spring in the vicinity of the refuges. You can also buy food and book a hot meal and breakfast. Bear in mind that the hot meals must be reserved on arrival.

Breakfasts are often prepared the night before and handed out so you can leave as early as you want the next day. As regards lunch, if you are passing a refuge between 12h and 14h you will often find a small lunchtime menu with choices, such as cheese and omelets, pasta, Corsican soup, and plates of smoked charcuterie. If you order dinner (remember to ask for it as soon as you get tot he hut!), it is usually served from 19h onwards. There may be more trekkers than seats available, so be patient. Dinner usually consists of three courses which vary from hut to hut. Bear in mind that you will be in the mountains, so don't expect over elaborated dishes. Also, you will be expected to bring your own knife to mealtimes, so don't forget to carry one!

Menus vary from one hut to the other and their meals usually depend on the stock they have. Hot dinners can cost between 15-20 euros, while breakfast and dinner cost around 8-12 euros each. Refuges are the only places where you can buy food and get drinking water along the trail. However, there are some stages where you can go shopping in the villages below.

All refuges have an indoor kitchen that you can use. These are equipped with gas, water, and kitchen utensils.  Remember to always keep a lighter, or match with you! You might find there are only 4 gas rings available for a large number of hungry trekkers, so try to be patient.

Where is the GR20 route?
GR stands for Grande Randonnée, which means something like "big excursion" in French. The GRs are a network of long-distance trails in Europe located mostly in France, Belgium, the Netherlands, and Spain. The GR20 is considered to be the most difficult of all these routes and is located on the French island of Corsica, Corse in French, on the Tyrrhenian sea. Its Corsican name is Fra li Monti, which means "across the mountains" in Corsican.

What is the best season for the GR20 hike?
If you are planning your GR20 trek, we advise you to go in late June or early September. During this time, most huts are open and the weather is not too hot. Also, the trail won't be as crowded as during July or August. 

Between November and May, there is snow on the trails, which makes the trek quite dangerous. Also, during these months there are no hosts in the refuges, which means that you have to carry all the food. During winter, from February to April, the GR20 can only be completed by experienced cross-country skies with a professional guide. This winter variant of the GR20 is known as l'Alta Strada.

How do I get to Corsica?
As mentioned above, Corsica is a French island on the Tyrrhenian sea, also known as Corse in French. You can reach the island either by boat or by plane. There are 4 airports on the island, 2 in the north and 2 in the south. If you are planning on starting the trek from the north, then it is advisable to land in Calvi (CLY). If you are planning on starting from the south, the closest airport to Conca is Figari (FSC). The airlines flying directly to the island are Air France and Air Corsica, with flights departing from  Paris, Marseille, and Nice. The flights take usually 1 to 1,5 hours.

You can also reach the island by boat. Between April and September, there are daily ferry rides from Toulon, Nice or Marseille. Of course, this option is cheaper than the plane but it also takes longer. The ferry ride from the coastline to the island takes around 6 hours. If you want to take a ferry to the southern section of the island, it will be even longer.

How do I get to the starting point of the GR20 walk?
The starting and endpoints of the GR20 are Calenzana village in the north of the island and Conca in the South. Vizzavona is the midway point and easily accessible if you want to walk one half of the trail. 

Once you get to a port or airport in Corsica, it is quite easy to get to the trailhead, both north, and south. If you land in Calvi (north), you can take a 30-minute ride by bus or cab to Calenzana. A cab usually costs between 20 and 30 euros per ride while the bus costs around 8 euros. If you land in Figari (south), we recommend taking a bus to Conca. The ride is 2,5 hours long and taking a taxi to Conca can be quite expensive.

GR20 Corse - Should I start from the North or from the South?
You can walk the GR20 trail in either direction, from north to south, or from south to north. Which is the best option? Well, it depends on your physical condition and what you expect from the whole experience. The trail can be divided into two parts: the northern part starts in Calenzana and stops in Vizzavona. It is the most difficult part, because of the steep and rocky path, but it is also considered the most beautiful half. The southern part of the Gr20 goes from Vizzavona to Conca (or the other way around) and is easier, but less spectacular. The Coscione plateau with its green meadows is, however, quite breathtaking. 

You can walk in either direction through the whole trail or you can choose to walk any of the two halves. The traditional route starts in the north and ends in the south. Since the GR20 can be quite crowded and most hikers walk southwards, some people recommend starting from the south and making your way to the north.



The GR20 is a demanding but safe trek and the trail is quite well signposted along the way with red and white rectangles on rocks, boulders, and trees. There are also small stone heaps along the trail. Alternative paths are marked with a different color.  Bear in mind that it is easy to get on an alternative path without meaning to or to lose your way, so having a good map and a compass is necessary.

Huts do have electricity. However, charging your phone or camera can be quite a challenge given the number of trekkers and the limited number of sockets. Having a charged phone is not just a luxury, it is also a safety measure. You might not need it for yourself, but if you come across an injured trekker, you will need to ask for help and a charged phone is key. Make sure to carry extra batteries with you or a solar charger.


GR20 and Covid-19

The GR20 is a perfect option to avoid having to stay in overcrowded hotels in coastal countries and to socially distance oneself from others. But obviously, you still will have to spend the night at huts where you will certainly not be alone. In order to keep the COVID-19 pandemic under control, the following must be taken into account:

- Do not visit the Huts if you have symptoms!
- Huts aren't allowed to work at full capacity, so make sure to book your stay in advance
- Bring your own facemask!
- You must bring your own sleeping bag, liner, and pillow cover
- Bring your own travel towel
