From Rolleston River Track

Climbable via the giant gully that rises steeply for 1100 metres from the Rolleston River track (1.5km upstream of the railway bridge). This gut can be threatened by rock or ice fall in almost any season, and is invariably a very steep ice/loose scree climb for the final 200 metres to the col between Mt Philstine and its northwest summit (1780m). Warnocks Knob should be used as the preferred descent route.
