The ridge forming the left side of the amphitheatre is steep but helpful. Start on the front face (outside the amphitheatre) and climb a groove to the crest (20m). Follow the crest, with the crux at mid-height, a steep blocky section with some good flakes, to reach a ledge on the left (40m). Finish by the easier upper crest (60m).
Note: To make the route Grade II but not as good, start inside the amphitheatre and climb a turfy corner which forms the right side of the ridge to reach the easier upper crest.
