As the title says, this was truly the adventure of a lifetime. Canoeing across Mendenhall Lake was beautiful, but the real treat was getting to climb around the glacier itself - and our group of 10 were the only people on it at the time. Apparently only 50 people can do it per day. We were lucky enough to find a massive ice cave to enter and it was, by far, the coolest thing I've ever done. Pictures do not do it justice at all. It was unbelievable! Our guides Spencer and Abbey were the best. Super knowledgeable, funny and skilled. They made sure we were always safe while taking us across some pretty serious terrain in order to access the coolest areas. You can trust them completely.
To sum it up, not only would I recommend the Liquid Alaska Mendenhall Glacier Ice Adventure, I would say you shouldn't even consider anything else for your time in Juneau.
