To the west of the main sector, near Route de Sully. Sitstart on the right, traverse to the left and exit after the thin vertical crack with a small pocket. NB: the boulder needs to be rebrushed.
From Route de Sully , take the blue path n°6 in the direction of La Ligne Noire (East). Walk 10m then follow the blue path n°6 towards the North (which goes down while remaining parallel to Route de Sully). Walk about 20m, the boulder is 10m on the right.
