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.

Between Isère and Vercors, Saint-Marcellin has long prospered thanks to trade and its famous cheese. Its old town center preserves stone facades, narrow passages, and a few beautiful bourgeois houses.
