I hiked a GLACIER in New Zealand. Holy crap! Along our journey through NZ we got to do some of the coolest and most adventurous stuff. This one def is up there with my favorites. We started at the bottom in summer clothes and by the time we got out on to the glacier, I was in winter gear. I wish I had paid a bit more to go up to the top - but alas, this experience was amazing and something I'll never forget.
*Excuse the quality of photos. I didn't feel comfortable bringing my big camera on ICE. :)
