My husband, preteen grandson and I went on the Denali Zipline tour as part of our Alaskan vacation in August, 2013. Can't say enough good stuff about the entire experience. It's perfect for families with older kids, and for retirees too. Even a terrified person in our group got the "hang" of it and emerged victorious at the end. No matter your experience level, the guides are well trained, professional, and sincerely want to assure that each guest comes away with a positive experience. They insist that rules are followed, but insert a lot of humor (very funny guys) and offer friendly encouragement... well done AJ and Dan! Fantastic guides. No all ziplines are alike. This one is awesome!! Very highly recommend.
