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.

Hello, this hike passes through private property: from the Pas du Touet towards the Pas de St. Vincent, crossing the ridges is prohibited. I am a trail marker for the FFRD and I manage the area.
