With a stiff climb directly away from the lake to gain the ridge as comparison, the traverse to Mt Benson is a gently rise.
From the summit, continue NW along the Lockett Range a short distance to SH1672 and a big scree then tussock descent to the base of a greywacke gendarme that forces a sidle on the left (Cobb Valley) side under SH1503. Regaining the ridge, continue to descend (perhaps with a small deviation to tarns on the left) to the 1340m contour where a bluff forces a diversion to the left, dropping into the trees before contouring around to regain the ridge in a saddle.
After climbing a knoll the track swings west then climbs again, swinging back to the north. Passing a small tarn (accessible water, usually), the track rises through a hanging valley (good camping) under Waingaro Peak to the track junction - left and down to Fenella Hut or up and right to sidle under Waingaro on the route to Lonely Lake.
