Mt Hiwiroa

The west branch of South Temple Valley is accessed via a heavily wooded valley behind the South Temple Hut. Follow the stream and occasional cairn, to GR G38, 484702, gain height to the south west to reach the saddle into Watson Stream. Climb a grade 12 chimney to reach the summit snowpatch.

Cross the south branch of the stream before the gorge, near 497694 on G38. Ascend the steep slope through the beech forest close to the crest of the ridge. Once open ground is reached continue along the ridgeline to the summit. The first ascent party did not use a rope. Seven hours from carpark to summit.
