GR20, Corsica
GR20, or Grande Randonnée 20, is Corsica's long-distance haute route. The trail runs along Corsica's watershed. It starts in Calenzana in the north and ends, 180 km later, in Conca in the south. If you would like more information you can find it in this post I wrote for ClubTread website.

GR20 is split into 16 stages (étapes) each ending in the relative comfort of a hut (refuge).

Anahid and I hiked the GR20 in 12 days in September 2006.
