On an isolated boulder, in the parcel 120. Start completely right at the angle, to the right of an evident crack, traverse to the left and exit at the end.
From the parking lot, take Le Chemin des Cavachelins, pass under the motorway, take Le Chemin de la Vallée Ronde on the right and continue up to a bend to the right. The boulder is on the right, 30m from the path.
