On the boulder of Finale Nage Libre. Sitstart right as for Aronnax, climb the overhang to the left as for Nautilus but exit completely left (without using the good hold of Nautilus).
On the boulder to the left and above Court Métrage, between the main sector and the sector of Rien dans le Ventre. Climb the slope to the right of Le Mur à Piat for 50m; the boulder in in a small chaos just under the path on the ridge.
