Long traverse to the right on the boulder of Pourquoi Tant de Haine? (orange n°34), along the 25 Bosses path, in between Querelle de Chapelle and Coup de Torchon. Standing start at the left facet and traverse under the roof with a low crack as for Paul Haine, continue with the upper horizontal crack, pass the angle and exit 3m further by a mantle on slopers.
