About twenty meters past Irréversible, on the East face of the boulder with Le Spoutnik 2 (blue n°52) (boulder with the letter "K"). Sitstart (without crash-pad) to the left of Partie de Plaisir (red n°28) with a good diagonal hold, take the thin horizontal crack and climb the prow to the left towards a good sidepull on the left and exit with a mantle on slopers.
