On the boulder of Incassable. Sitstart at the angle of Incassable, make a big dyno to a good hold on the left, traverse with top slopers after the tree and exit by a mantle at the end of the left face.
From the parking lot of the equestrian centre, follow La Route d'Arbonne à Achères for 250m; the boulder is 30m above, shortly after a TMF mark on a tree.
