From Bannister Rock

The route of the first ascent of Lyttle Peak is unknown, but the easiest route appears to gain the steep south-eastern snow face at the bottom left, through a break in the line of bluffs below the face. To reach this point from the Lyttle-Darkwater confluence, ascend a tussock ridge past numerous large boulders, an then traverse north across the top of a prominent waterfall to gain a sloping shelf leading towards Lyttle Peak.
