Can't say enough about this excursion. We went on a shuttle to the helicopter site.
We were suited up with a jacket (lightweight outer jacket), gloves, pants, boots, and a fanny pack (with water and snack). Then on a helicopter out to the glacier. We were given crampons, helmet, and ax...and were guided around the glacier for 2 hours. We drank water from a water fall. What an unbelievable experience. Then copter ride back.
Words of advice - you can only bring a phone/camera and what is in your pack. Everything else stays at the airport in a secured bag. They outfit you - and you must wear what they provide. If it's cold, wear your winter jacket and their jacket over yours. Jeans or yoga pants are warm enough under the pants provided.
Enjoy - it is the experience of a lifetime!
