The flight and cruise is an experience not to be missed. After take-off from Queenstown the mountain scenery is superb as the aircraft climbs to the west between the peaks, and the approach into the Milford Sound airport is simply stunning as the flight takes you from the ocean along the Sound. Even better, after the cruise you get to do it all over again!
I was lucky enough to occupy the RH seat in the Cessna C208 Caravan beside the pilot (Matt) who was a very competent and experienced, and had an even better view than any of the other passengers. If you do just one thing in Queenstown, this has to be it.
