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

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.
