From Vizzavona to Calenzana, hike the entire northern GR20 in 9 days of challenging, self-guided walking, with optional luggage transfer and nights in dormitories and tents. This demanding section is almost 100 km long.

The northern section of the GR20 is a demanding hike covering almost 100 km, crossing landscapes with a very Alpine feel, and is considered to be more mineral than the southern section. The route starts in Vizzavona along the Agnone. You'll climb up to the Pointe de Muratellu before descending to the Onda sheepfolds. Following the alpine variant that leads to the Petra Piana refuge, the GR20 will take you up the ridges of the Serra di Tenda. This is followed by a wild stage offering panoramic views of the glacial lakes of Risono, Melo and Capitello, with a long traverse of the granite ridges to the Manganu refuge. After crossing the Camputile plateau, the trail passes Lake Nino, famous for its pozzines and lush green meadows, before reaching the Vergio forest. Past the Tighjettu refuge, the GR20 crosses the Cinto Massif via the Carrozzu and Ortu di u Piobbu refuges. Finally, the route ends at Calenzana, offering panoramic views of the Gulf of Calvi.  This version requires serious preparation and good mountain experience. If you'd like to do the route the other way round, please don't hesitate to contact us.

Day 8

Haut Asco to Carrozzu

Starting from the Asco ski resort, the trail begins with an ascent towards the Bocca di Stagnu (1979m). Although this section is short in terms of distance, it is demanding due to its gradient and the type of terrain. From the pass, the GR20 continues along the ridge, offering impressive views over the Asco valley and the Gulf of Calvi. After passing the Bocca di a Muvrella and its lake, the landscape is mainly composed of majestic rock formations and stretches of scrubland. Descending towards the Refuge de Carrozzu, you cross a series of sloping rocky slabs, followed by the Spasimata footbridge. Some passages are secured by chains, but caution and concentration are essential.

A steep, technical scree slope will then take you to the plateau, the Bocca di l'Innominata, at an altitude of 1,912 metres. The view from here is exceptional, giving you the impression of overlooking all the bays in northern Corsica as far as the eye can see.
