On the West face of a boulder up the crest, in the sector Princes de ce Monde. Start just left of a tree with the hands on a flake, traverse on slopers and a pocket and exit by a mantle to the right of the second tree.
From the parking lot of Le Carrefour du Rocher des Princes, follow La Route de Montmorin (blue path) for 100m, take a small path to the right before the bend and follow that one up to the crest.
