On a boulder about 150m East of Voile Solaire, to the north of Tree Hugger. Sit or crouching start with the slopers on the left and climb the left arete to take the large pocket right hand and exit on the right.
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.
