>>2519528January is on the Alpine Nature Walk in Lewis Pass. February is on the way to Carroll Hut in Arthur's Pass. If you want a good multi-day hike in that area, you can cross the Kelly Range via Carroll Hut, then head up the Taipo River, over the Harman Pass, take a side trip to Barker Hut, and head out via the Waimakariri Falls Hut and Waimakariri Col. The view from Barker Hut is very good (pic related).
