Difficult pass at first, especially in the heat. Easier after the first third. Be careful of the unlit tunnel 1 km from the summit. For added peace and quiet, the road leading up to the pass is closed to traffic from 4 p.m. to 6 p.m.

One of the most difficult passes in the Pyrenees and in France with really hard percentages that go on and on. When you leave the road to pla d'Adet you go up a small road of goats, it's really nice in the middle of sheep and cows. Be careful when crossing the tunnel near the summit because it is not lit and animals may be in the tunnel. The view is magnificent it is really a must. You just have to go down the road, so watch out for the cows because you pick up speed very quickly.

Very beautiful point of view on the surrounding peaks as well as on the peak of Bastan which awaits you. The night at the edge of the lake is very pleasant.
