The most popular tops crossing to Townsend is from the Minchin valley via Minchin Pass. From Minchin Biv it is a straightforward amble up to Minchin Pass, then up the the ridge on the southern side of Waterfall Creek basin. It is necessary to traverse points 1461m, 1526m, 1638m and 1731m and drop from point 1731m down towards point 1183m. Don't drop directly down to Townsend Hut, which visible from the Divide in fine conditions, as there is a band of alpine scrub on the face just above it. From point 1183m follow the lip of the fault scarp down to the Hut. Allow 4-5 hours in good conditions for the crossing from Minchin Biv.
