Characteristic wall on the East face of a boulder above the blue path. Standing start, dyno to a pinch right hand, climb the wall with an undercling and exit directly in the slab.
From the parking lot of Le Carrefour du Rocher des Princes, follow La Route de Montmorin (blue path) for 100m, take a small path to the right before the bend and follow that one up to the crest.
