On the boulder of "Le Yack", above the thalweg, in the Eastern part of the sector. Exit at the middle of the ledge with good holds.
From the asphalted road, follow La Route Marie-Thérèse for 300m and go up the thalweg by a small path. The boulder is one of the first ones, on the right up the slope.
