In the sector of Le Carré d'As (black n°30), to the right of La Route de Bellevue, 50m after having crossed the blue path n°5. Start on the slab completely left, traverse with top holds, downclimb with a pinch, pass a second angle, take the underclings and exit in Façon Bourrin, at the third arete (27 moves).
NB : the last face of the original traverse is lichenous (August 2010).
