Pass with a beautiful view! If you go up the Hourc road, it's a steep climb at the end, but it's worth it!

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.
