On a boulder about 70m East of Voile Solaire, to the left of Soleil Volé. Start on the stone 1m right of the prow using small slopers in compression, climb direct to the large pocket and exit as for Tonnerre Volé.
Head South from a point 20m West of the crossing of Route de Barbizon à Fontainebleau and Route de Clair Bois, picking up a small trail heading up the hill. The boulder is just left of this trail after about 100m.
