East Ridge

From Lake Te Kōhua head to the saddle between Mt Tūwhakarōria and Pt 2178. The East Ridge will take you to a false summit (which is just lower than the true summit). To get to the true summit wrap under the north of the craggy skyline to gain the true summit from the west.
P.S. My head did not crest the summit. Must have been climbed before.
