Loop on the boulder of "Le Bowling", 30m to the East of L'Apesanteur et la Grâce. Sitstart left as for Des Boules au Nez but instead of finishing by the prow, traverse to the right on the ledge, downclimb by the crack and exit in Le Trou de Boule 1.
From La Route de Pompadour, follow the esplanade path; the boulder is up the slope, 60m before the crossing with sur la gauche une soixantaine de mètres La Route de la Vallière.
