This route climbs flakes and cracks diagonally right up the right side of the penthouse. Either start ground level via some flared cracks to an obvious ledge(not well protected) or scramble directly on to the ledge from the gully on right. A good belay can be set here. Climb the steep left arching flake(crux) into the crack system above. Awkward climbing follows up the cracks, good gear available but sometimes not obvious. Be aware of the loose flake about half way up. After the tree step right onto easy terrain to the two bolt belay.
