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!

A charming town that's home to some of the Tour's iconic climbs. Stop and take a few photos of your bike in some of the picturesque spots you see.

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.
