On the boulder of Lame Fatale. Standing start right and traverse with low holds as for Le Pébroque but continue to the right on the ledge and mantle up at the top as for Lame Fatale.
Follow La Route de Bois d’Hyver for 1km. The obvious boulder is 200m past the crossing with La Route de la Roche aux Moineaux, on the right hand side, 50m into the forest.
