The South Ridge.

Climb to the ridge by way of a clearing through the bush, across the river and slightly downstream from Wilson’s Camp. From the crest of the ridge cross into a basin on the west side of the South Ridge of Rob Roy and traverse across this into a second basin to reach the foot of a mixed snow and rock ridge leading to the summit. The climb requires about 10 hours from Cascade Hut to the summit and a bivvy high on the slopes opposite Wilson’s Camp would be desirable.
