A very popular daytrip from Queenstown is a visit to the world famous Milford Sound in Fiordland National Park. You can travel by car or sightseeing bus. However, the drive is about 179 miles one way and requires almost four hours. A more scenic and much shorter option is aboard a small plane. During the half-hour flight, you will soar above glaciers and marvel at some of the Southern Alps’ most impressive peaks. Tours usually include a cruise through Milford Sound and sometimes other spectacular adjacent fjords.
