Climbed this one today and it was quite an interesting adventure. I couldn't find any track notes or gpx files anywhere online, so had to get a bit creative with the route. In retrospect, I think the easiest way would have been ascending via the saddle between the peaks, however we chose to take a more 'adventurous' route and go directly up to the peak from the regular path. Lots and lots of loose rocks on the route that we took along with some minor scrambling, a bit sketchy in places but nothing too difficult. A fair bit of Gympie Gympie too in places, but it was easily avoidable. There was quite a unique cairn at the summit - haven't seen one like it before. Glimpses of Spicers Pk and Mitchell East Pk on the way up, but more or less nothing to see at the summit. Still, another one ticked off the list.
I'd be interested to hear other accounts of people climbing the west peak, given it seems to be seldom talked about (and therefore presumably seldom climbed!).
