A seldom-completed circuit of the entire crater rim. Most of the crater rim is an exposed, easy scramble in summer time; with occasional ‘crux’ sections—some parties may require a rope. Suggested direction is counter-clockwise. This would give a couple of abseils and the easier climbing. Winter, however, involves a series of steep climbs and descents over some, dubious at times, ice formations. Direction is a matter of personal preference depending on how much steep climbing the party wishes to accomplish. It is best climbed clockwise. The best time to do the traverse, in winter conditions, is late winter when the ice has consolidated.
