Perhaps the most beautiful road in the Vercors? In any case, one of the wildest with its tunnels and narrow passages.

A small village in Isère nestled at the foot of the Vercors, Rovon preserves several discreet monuments from its rural past. There, you'll come across a renovated Romanesque church, old stone farms, and a few wayside crosses. A village to discover along its narrow streets and trails.
