My wife and I booked the 30 minute flight, which included landing on the snow above the glacier. The helicopter ride was the highlight of our trip to NZ. Bill, the pilot, was reassuringly safe and provided an informative commentary. The views over the southern alps and the two glaciers was simply breathtaking. We were blessed with a perfect day, weatherwise for our flight. I would highly recommend this company for this trip. We are still on a high a day later.
