From the head of the Rolleston River, climb via a steep, narrow couloir. This leaves the river via initial scree (K33 885121) and proceeds into a narrow rock gut for 200m before opening out to onto another scree slope. Keep the adjacent rock on the true left. Towards the top ascend diagonal rock gullies to join the west ridge on to the summit. Post winter route when avalanche risk is low.
