We took the Mendenhall Glacier Ice Adventure tour, with Griffin and Allison as our guides. These two were FANTASTIC! They're super knowledgeable, and very easy to talk to. These two did a great job assisting everyone, and being patient with the pace, and the questions from the group. From facts about the glacier, to creating steps for us in the ice, they were everything that we could have asked for in guides, and the glacier went well beyond expectations. I would recommend this tour to everyone coming off of a cruise, or just visiting Juneau. Don't let the price scare you off... this trip is worth every penny!
