We all went on a scenic flight of Mt Cook (the highest mountain in New Zealand) and landed on the Tasman Glacier which happens to be the largest glacier in the world.
It was a 50 minute flight The views were unbelievable, we had about 15 minutes on the glacier just enough time to have a snowball fight and time for me to build a snowmman. It really was an amazing sight and very worthwhile,but not as cold as you would expect.
