A really slick and well run operation made for an excellent day. I chose the full-day hike which I'd definitely recommend for anyone who has the time. You'll get much further up and see the interesting stuff. I think I would have been disappointed in the half-day hike. The provided gear was excellent, and we had plenty of time on the ice. The best thing though was our guide, Tom - really friendly guy, very knowledgeable, and intent on making sure everyone had a great time. Two thumbs up!
