Sitstart on the left and exit on the right on the head of the turtle. PS: This traverse has been opened before and might have a different name.
From the parking lot, take Le Chemin des Cavachelins, pass under the motorway and turn right immediately onto Le Chemin de la Vallée Ronde. Follow this path for about 500m. The boulder is then on the left of the path, opposite Mise en Scène.
