Corsica - GR20 North Self-guided

Itinerary:

Day 1. Arrive Vizzavona
Vizzavona is the midway point of the GR20. Nestled in the heart of a forest, there is a small railway station that serves as a hub of activity for hikers starting or finishing their GR20 treks. At the beginning of the 20th century, the hamlet was a popular resort for the English. From here, you can take the GR20 trail toward the beautiful Cascade des Anglais. Night in Vizzavona.

Day 2. Vizzavona to Petra Piana

The walk begins with a lead-in trail that emerges near Canaglia, a small hamlet nestled in the forest. From there, the path follows a mountain stream, winding past smooth rocks and inviting pools, all the way to a shepherd's cabin in a grassy clearing — the perfect rest stop at Tolla. The GR20 then leaves the forest and continues into a beautiful open valley, offering a striking contrast to the earlier part of the walk.Overnight stay: Petra Piana. Tent B/L/D/
