A legendary category 1 pass. Easier from Bielle because the magnificent Benou plateau offers a gentler incline before the final climb.

Short tour, climbed by a beautiful track. The 3 km of the trail are well worth the detour. Excellent winding trail, very narrow, some small hills, more technical passages and good rolling at the end. 2 large trees are lying down. And it's a beautiful forest. Return by track. To redo
