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.

After a long section of "classic" pass, we suddenly find ourselves on the side of a cliff with a majestic view 😍. The valley is not very long but magnificent. Many nooks and crannies to stop and take a photo.

Undoubtedly the most beautiful road in the Vercors, and certainly a delight for cyclists. The climb through Saint-Jean-en-Royans is quite challenging, with numerous sections at 8-9% gradients. It's possible to do it downhill by first climbing the Col du Pionnier.
