On a small boulder near the top of the hill, in the South slope, 80m to the West of L'Oublié. Crouching start with a good hold right hand, climb the ledge using a high heel hook and exit at the top.
From La Route de la Plaine Verte towards the parking lot, go perpendicularly uphill to the left 10m after a warning sign telling you not to climb on log piles. The boulder is slightly right, 10m under the crest.
