Perhaps the most beautiful road in the Vercors? In any case, the road to the Gorges du Nan has remained somewhat in its original state, narrow and without a parapet.

An impressive gorge that is worth a visit. The little road that runs through it is very narrow and it seems like the mountain is going to fall on you.

A beautiful cycle path that follows the Isère River. There are a few places to stop for a picnic, and there's even a water fountain. This is a good place to cycle during the summer months as it's generally cooler along the riverside, which is well shaded.
