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.

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.

I prefer the road option, but the Gorges cannot be compared to the Bourne Gorge that follows. Still a beautiful landscape.
