From Leatham Station follow a rough and narrow 4WD track on the true left of Boulder Stream to Boulder Forks Hut (6 bunks, standard). Just past the hut, go up McCallum Stream to just before a small gorge. From here, climb through forest onto the spur to the north and along to a saddle where the rocky summit pyramid begins. Alternatively, a more direct route is to climb steep loose scree out of McCallum Stream onto the open spur to the south. Where this merges into the north-west face, climb a gully (or good rock right of the gully) to just north of the summit.
