Loop on the boulder of "Le Bowling", 30m to the East of L'Apesanteur et la Grâce. Sitstart as for Boule-Versement 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.
