Parked near the SH73 bridge over the Otira River. Made use of the track up the spur on the TR of Barrack Creek. Once clear of the bush and scrub followed the line of least resistance through a series of tussock benches then rock fields until the ridge sharpened up a bit. Then followed the ridge all the way to the top where there is a large rock cairn. There is a little bit of easy scrambling involved over the last 300m.
It took 2hrs 30mins to the summit on the way up and was 10mins quicker coming down.
[These were summer conditions with snow and ice absent]
