Col de l'Arc walks

This easily accessed summit is located on a ridge between the "Vallée de la Gresse" and the Vercors plateau. It offers a breathtaking view on Belledonne, Les Rousses and a bit further Les Ecrins.

One of the peaks bordering the Vercors Regional Park to the east. Relatively easy to access, in good weather it offers a wide panorama from Mont Blanc on your left to the Écrins massif via the Belledonne chain. The climb via the Combe Oursière is less frequented than via Les Allières. A well-shaded route for most of the way.

A very beautiful hike offering superb views of the Grenoble region and the Vercors from the summit.

The hike starts at the hamlet of Les Blancs near Lans and takes us to Pic St Michel via the Chemin des Anciens and the Col de l'Arc. The return journey is via Les Allières and the Pierre Berchue viewpoint.

A circular route along old, little-used paths, allowing you to discover the natural wonders around the spectacular Crête des Crocs: the magnificent Arche des Crocs, the Pierre Fendue, the "Main", the Rocher de l'Ours and its unique view of the Roc Cornafion, and the Crête des Crocs and its bird's eye view of the Col de l'Arc and the Pic Saint-Michel. The main difficulty is finding the route, as the paths are very poorly marked. Please note: see practical information.
