Summer is a very pleasant small road by bike, it's cool and there is little traffic. In winter, it can be very cold

Great straight in soft gravel. The route remains pleasant with views of the Chartreuse while staying on the flat.

The col de la Croix Perrin, located at an altitude of 1218m on the border of the municipalities of Autrans-Méaudre en Vercors and Lans-en-Vercors, is a major site for forestry, hospitality, and history. Here you take the direction of the Espace Naturel Sensible de la Molière-Sornin. It is said that here, a certain Mr. Perrin had an unfortunate encounter with a bear, when they were still present in the Vercors.

The path runs for 3.2 km between the two municipalities, with a part on stilts to preserve the wetland; the second part is a forest track in the middle of the woods. The river is crossed thanks to secure footbridges.

Nice flat gravel path to avoid the very busy road between St Laurent du Pont and St Joseph de rivière, up to the Demay bridge. Runs along the l'Herretang canal
