It takes the best part of a day to drive from Glenorchy to Milford Sound, but it's only 15 minutes by helicopter. Heli Glenorchy has a three-hour Milford Sound heli-cruise-heli package ($825) and a wilderness drop-off so that you can walk the last few kilometres of the Milford Track to Giant's Gate Falls before being whisked back over the mountains ($865).

It has a host of other flight options, including West Coast beaches and glacier landings.
