Just right of Le Coquillage, on a 6-7m high boulder. Standing start at an evident gully, make a mantle, climb the wall above and exit slightly left on the pillar.
From the parking lot, follow Le Chemin de la Plaine de Chanfroy, which becomes Le Chemin de Milly, for 1km600 and turn left at the GR; the boulder in in the chaos to the right of the path.
