No climbing during hunting season: from mid-September until March.
Just after La Balade des Confinés, along the path that forms a loop. Sitstart without crash-pad with sharp crimps, join the arete and exit on its right.
From the village of Auvers, follow Le Chemin du Puy Rond for 200m, take a small path in the forest and turn right at the crossing. The boulder is just right, before a descent.
