The best way to see the glacier would have been to take a helicopter ride and explore it from great heights. However, backpackers budget doesn't really stretch that far so we did a half day glacier walk.
Describing it as a walk makes it sound quite mild, it was a trek. We got kitted out in coats, boots etc and given crampons to hold for when we started climbing on the ice. We were advised to layer up so knowing how cold I get I took it to the extreme and had 5 layers on, even I was too warm once we started going!!
It was a great thing to do as it will probably be the only glacier I will ever climb. The sun came out as we reached the top and great views could be seen.
