The climb starts on the ledge at the 2RB belay inside the cave on the right hand side of the buttress. However, its best to just belay from the ground, walk in along the ledge and place a long sling on the belay to avoid rope drag. Traverse left past the upper line of RB's to the arête. Continue up the crack before moving right onto the wall. 8RB's to 2RB anchor.
