The best time to hike the Milford Track is during the Great Walk season, which runs from October to April. If you are doing Milford Hike end-to-end, we recommend December to March as the ideal time, but day hikes on some sections of the Milford Track are fine in the shoulder months of October, November and April. Summer (December – February) and early Autumn (March) bring mostly mild or warm days in Queenstown and Fiordland National Park, but it is worth noting the mountains and valleys of the Milford Track can see rainfall at any time of year so it is always best to be prepared for cold and wet conditions. From May to September, it can be cold and wet, with ice and snow on the Milford Track, so these are definitely months to avoid hiking the Milford for most.
When considering the best month to do the Milford Track, consider the shoulder months if you prefer less of a crowd. November and early December as well as February and April can see less hikers and also better availability in Queenstown, where you'll likely stay pre and post hike. Keep in mind the Christmas and New Year holidays often book out in town, and minimum stay periods apply, so be sure to book your Queenstown accommodation with your Milford Hike to avoid disappointment.
