An example of how the trip can run:
Meet your guide in Wanaka, check gear and drive to the Fantail Falls carpark on the Haast Pass Highway (1hr). Cross the Haast River and ascend through the silver beech forest and open tussock tops to Brewster Hut (4-5hrs)
Awaking early we trek above Brewster Hut, sidle around towards the terminus of the Brewster Glacier or enjoy a trek up the slopes of Mt Armstrong. In the afternoon walk back down to the Fantail Falls carpark and drive back to Wanaka, stopping along the way for ice cream in the small rural settlement of Makarora.
