The glacier walk was my favourite activity in New Zealand by far. It was well organized and the guides were great. They give you all the gear you require. We spent nearly 3 hours on the glacier and it was amazing as was the helicopter rides up and back. It wasn't very difficult physically, but was done at a relaxed pace. Our guide, Milo, did his best to make our trip interesting and enjoyable. The views were great and the ice caves were too. I would highly recommend this trip for value, excitement, and something you won't get to do too many times in your life. Loved it!!
