Absolutely stunning day. Lots of snow and ice and windy up along ridge line. Ate lunch 100m above tree line and with absolutely stunning views of Lake Rotoroa. Perfect clear blue skies, windy on ridge line but gorgeous day. Below tree line to Sabine Hut was constant steep track. This park of track was most treacherous on legs but Sabine Hut is a beaut. We saw heaps of fan tails below tree line, including an all black fantail. We have one Hut mate from Germany. We did not see a sole on our entire walk!!!
