Glacier Southern Lakes Helicopters Queenstown offer a selection of scenic flights that fly over the big names: Lake Wakatipu, The Remarkables, Coronet Peak, Kawarau Gorge, Shotover River and Skippers Canyon.
I did the The Remarkables, with Landing - (Flight Tour 101):
Sensational photographic opportunities at 5,000 feet. We landed on the Remarkables spur, overlooking Queenstown with Coronet Peak in the distance. Roughly 20 minute flight for NZ$195 (includes shuttle from Queenstown pier).
