There is a bouldery start to gain the first horizontal and clip. Followed by easier moves up the slab to the bulge. The crux kicks in between the third and fourth bolts when the climb reaches the same level as the large scooped out features to your left. Work up through interesting and thin face moves, clip, breath and continue to the top.
Listed as 6b under the French system.
Walk to the right-hand side of the small parking pullout. The route starts just to the right of Short Crack which uses distinctive glue in loops which are unique to the area.
Closely spaced bolts, and an old piton (don't bother clipping this) to a two bolt anchor with an odd flimsy non locking steel qucklink/carabiner thing.
