Col de Sonnaize (782m) walks

A short walk around the Combe de Saint-Genis with the cliffs of Musan, Épenet and Pierre Chauve and the Romanaise plain in the background.

A very pretty and long hike around the Combe d'Oyans with beautiful panoramic views of the cliffs of Musan, Pierre Chauve and L'Epenet. The ruins of Rochefort-Samson Castle offer a beautiful view of the valley. Information board at the summit.

A very pleasant short hike. Much of the hike is in the shade. The view of the Vercors is magnificent when you reach Pas du Loup.

Large circular route covering the main ridges delimiting the upper basin of the Portail de Beauregard: ascent via the wild Vachères (off-trail), passage through the Cols de Sonnaize, Pas du Loup and Tourniers, steep climb to Pas de la Pierre to cross the long and beautiful ridge of Montagne de Musan to Pas Pourceau, descent via the "Pré de Cinq-Sous", the Cols des Cordeliers and Marchands, finally the Ravin de Combins to the Passage du Tour and return to the village via the Portail.

A "wild" route at the start, two caves to visit and a magnificent panorama to admire from the Montagne de Mussan, covering a large part of the Vercors, make this hike well worth the effort.
