From the head of Lake Rotoroa a track climbs a steepening face on to a spur. At the bushline climb onto the Mahanga Range and follow it up to Mt Misery. The hut below (4 bunks, basic) can be difficult to locate in fog.
Southern end of the Mahanga Ra, possibly in the Spenser Mts.
Above Lake Constance follow the West Sabine to a basin and a long scree fan. Climb carpetgrass and moderate rock beside a small gorge and traverse to a tussock shelf (or follow the Sabine true left, and to the right of bluffs, onto the shelf). Head south-west towards a col, and then the north ridge (very loose) to the summit pyramid.
From Waiau Pass the ridge is broad and easy, later narrowing. When an impassable notch is reached, descend south to a shelf and regain the ridge higher up. The remainder of the ridge is pinnacled.
South East Face
From near the bottom of the Waiau Pass route and the Waiau River, a tussock spur leads to a scree basin south-east of Mahanga. The East Ridge is gained from a snow face.
