The trail begins on the gradually inclined Deadman’s Track, up a spur leading to the rounded tops of the Whanahuia Range.
Shortly after starting, a junction is reached, left leads to Rangiwahia Hut. The right-branching trail continues to climb steeply at first through the forest and then eases off from about 1050m. At 1200m the trail deviates, heading directly east up towards Mangahuia, about 4km distant. Once the tree line is cleared views back down the ridge open up and tussock indicates arrival on the tops. DOC’s orange triangles are replaced by poles from here.
After about two hours, the 1500m contour is reached and a short 50m descent is required before the final ascent to the Whanahuia Range and the summit of Mangahuia (1583m). In winter, these tops can be covered in rime ice so dense it’s like light snow cover. It’s beautiful, although in good weather the afternoon sun may melt much of it and turn the trail into a trickling stream.
North of Mangahuia, the poled route undulates over open tussock, soon reaching a westward turn that leads back to Rangiwahia Hut. Continuing past the junction, the trail drops gradually north-east to a small picturesque tarn-scape suitable for camping. Soon after, the trail turns east and descends steeply to Triangle Hut.
