The Vercors Plateau (also known as the Vercors Massif) is one of the most spectacular natural jewels of the French Prealps, located straddling the departments of Isère and Drôme, a short distance from Grenoble. This vast limestone mountainous area, which extends over more than 206,000 hectares, is famous for its unique geological conformation that earned it the nickname of "fortress": an immense rocky block surrounded by impressive vertical cliffs, deep canyons, and spectacular internal plateaus.

La Combe Laval is one of the most spectacular scenic roads in the Vercors massif. The D76 was carved into the rock face between the 19th and 20th centuries and passes through a succession of tunnels, ledges, and sections suspended over the valley.

Spectacular road carved into the rock in the heart of the Vercors. Vertical walls, numerous tunnels, and the Bourne stream accompany the route in a wild and evocative setting. One of the most scenic roads in the Vercors, not to be missed by bicycle.

A very beautiful route. Unfortunately, motorists think so too. Even campers squeeze through the narrow road—so be even more careful than usual!
