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.

Isolated in the heart of the hamlet, the chapel of Saint-Jean-le-Fromental watches over the old Dionay cemetery. Built in the 12th century, it retains its simple Romanesque architecture and a nearly intact silhouette. It is listed as a historic monument.

Listed among the Most Beautiful Villages in France, Saint-Antoine-l'Abbaye surprises with the richness of its medieval heritage. The Gothic abbey church overlooks a collection of cobbled streets, half-timbered houses, and terraced gardens.
