GR20 is considered the most difficult – and one of the most beautiful – treks in Europe for a reason. It traverses the island of Corsica diagonally following the high granite barrier of mountains, offering some fantastic scenery. The GR20 north section will take you from Vizzavona to Calvi on the north coast.
Your accommodation will be in a variety of camps, refuges, gites or shepherd’s cabins, situated in places of exceptional beauty. All meals are prepared for you by your hosts, and we will transfer your main luggage at selected points during the trek, so you do not have to carry a heavy load all of the time – a real bonus adding to the enjoyment of the walks.

Day 1: Vizzavona
Vizzavona is the midway point for the GR20. There is a vast forest with a small railway station nestled at the heart of it. It is often a hive of activity for walkers setting out or finishing up their treks. You can settle into your accommodation and enjoy a stroll in the woods or relax at the nearby rock pools. At the beginning of the 20th century, the hamlet was a popular resort for the English, taking the GR20 path towards the dazzling ‘Cascade des Anglais.’
- Overnight in dorms at a hotel in Vizzavona, dinner
Day 2: Vizzavona to Petra Piana | 13 km
The start of this walk is a lovely lead in a trail that will come out near Canaglia hamlet. From here, you walk alongside a mountain torrent with sun-baked smooth rocks and enticing rock pools. A little shepherd’s cabin and grassy clearing make for a perfect rest stop. Next, you continue to the edge of the forest and emerge in a beautiful open valley. In total contrast to the first part of the walk, you continue up the valley enjoying the stunning views. Night camping at Petra Piana.
- Walking: 13 km, 5 h ↑1150 m ↓100 m
- Overnight in a tent in Petra Piana, breakfast, picnic lunch, dinner
- No luggage transfer – your main luggage will be transported directly to the Day 4 accommodation
Day 3: Petra Piana to Camputile Plateau | 10.5 km
From Petra Piana, a short uphill section takes you to the high ridge above the refuge. The trail is rocky, almost lunar in ambience. You pass a mountain col and continue on the high route. The views are spectacular, with Corte, the island’s historical capital, in the distance and a series of wonderful glacier lakes to discover. From the small Brèche above Lake Capitello, you plunge downhill to Manganu refuge, situated on the edge of the Camputile plateau. The shepherd’s cabin Vaccaghja is 20 min further on across the plateau.
- Walking: 10.5 km, 7 h ↑700 m ↓940 m
- Overnight in a tent in Camputile plateau (Manganu Refuge), breakfast, picnic lunch, dinner
- No luggage transfer
Day 4: Camputile Plateau to Col de Vergio | 14.5 km
The GR20 is well-marked, leading gently uphill, a relaxing walk through beech woods, and across the spongy green turf to the Lac de Nino. A morning stop to have a snack and relax on the banks of the lake. At 1743 m, this glacier lake is in a lovely, sheltered bucolic spot, surrounded by spongy peat, with runnels of water and wells, ideal grazing ground for ponies and other animals in the summer. The air is fresh, tinged with the scent of alder and the fragrance of the high mountains. From the lake, a classic walk leads along a high ridge with magnificent views and the occasional blue glint of the beckoning sea. Finally, you drop down at the Col St Pierre to join a flat horseshoe-shaped trail to Castel di Vergio, the island’s small ski station.
- Walking: 14.5 km, 6 h ↑570 m ↓750 m
- Overnight in dorms in a gite in Col de Vergio, breakfast, picnic lunch, dinner
- Luggage transfer included
Day 5: Col de Vergio to Melarie Valley | 13 km
Following the GR20, you walk to Radule, a huddle of stone cabins camouflaged against the mountain rock. The GR20 trail follows the Golu torrent up the valley towards its source. Midway up the valley, your route crosses the torrent, a good place to take a break on the smooth sun-baked rocks, a paddle and a swim for the brave. The trail shortly leaves the floor of the valley and heads up to the ridgeline. There are clear views of the villages dotted on the west coast and the indented outline of the island in the sea. The refuge Ciuttolu di I Mori (2000 m), the highest refuge in Corsica, is situated between two daunting mountains, the Tafanatu and Paglia Orba. You can enjoy a high, alpine environment; these massifs are home to the wild mountain mouflon (a wild sheep). From the refuge, you head for the Col de Foggiale. From the pass, the GR20 falls away steeply downhill, a stunning descent through a chaos of sharp granite rock and giant, grand, old pine trees. Once down to an altitude of 1400 m, you cross the Viru torrent, and the approach to Vallone cabin begins.
- Walking: 13 km, 5 h 30 min ↑950 m ↓970 m
- Overnight in a tent in Vallone Bergerie, breakfast, picnic lunch, dinner
- No luggage transfer – your main luggage will be transported directly to the Day 6 accommodation
Day 6: Melarie Valley to Haut Asco | 7 km
Today is a tough, high-altitude mountain walk. You make your way uphill progressively to the foothills of the Monte Cinto, the highest summit on the island. The climb is steep, rocky and slow. After a couple of hours, you arrive at Bocca Crucetta; a ridge leads to the daunting ‘Pointe des Eboulis’ at 2607 m; this is the highest point on the GR20, the view is spectacular. From here, the path plunges to the small lake on the other side. The trail continues downhill; the scree, the rocks, and austere décor give way to a river and woods as you approach the old ski station of Haut-Asco.
- Walking: 7 km, 8 h ↑1200 m ↓1200 m
- Overnight in dorms in a gite in Haut Asco, breakfast, picnic lunch, dinner
- Luggage transfer included
Day 7: Haut Asco to Calvi | 12 km
From Haut Asco, a superb ascent takes you to Bocca Di Stagnu (2010 m) at the foot of the Muvrella (2150 m). From Lake Muvrella, the view over Calvi bay is incredible. After Carozza refuge, you continue the descent to Bonifatu. Transfer to Calvi for overnight.
- Walking: 12 km, 7 h ↑650 m ↓1530 m

Picnic lunches are included (please bring a Tupperware for rice, pasta, lentils, couscous salad).

Difficulty & terrain
The GR 20 is considered the most difficult trek in Europe for a reason. Overlooking this fact could put inexperienced walkers in big danger. Do not overestimate your skills, and prepare for your trip properly. The GR20 is for hikers in excellent physical shape who already have solid experience of high mountain trekking over several days. The walks are long, between 6-9 hours a day, sometimes more. You can expect steep uphill and downhill sections with up to 1000 m altitude gain some days. The temperatures will range, and weather conditions can be severe. You need to be sure-footed and not be afraid of heights; the terrain is rocky and can be slippery at times (read more about difficulty grades). We provide you with a Travel Dossier complete with an IGN map and Topo guide. During your hike, 24-hour phone assistance will also be able to answer all your questions and, if necessary, give you useful tips for the smooth running of your stay. We strongly advise you to follow only marked trails and never try to shorten the path through the unknown and unmarked terrain.
When to go
This trip is available to commence on Sundays only between the beginning of June and the middle of September. Other days are available on request only. The climate of Corsica is Mediterranean on the coast, with mild, rainy winters and warm, sunny summers, while in inland areas, it gradually becomes colder with increasing altitude. The best time for hiking in the mountains is from June to September.
