In the East sector of the area, sitstart on the right in the overhang and exit far left with a mantle.
Acces: from the village, follow Chemin de la Butte Blanche/GR13 for 2000m. This is where the GR13 makes a sharp bend to the right, towards the southern sector with Opium. The rounded boulder is 50m to the North of Chemin de la Butte Blanche/GR13, just underneath the ridge with the blue marked path.
