This was a first-time zip for my wife and I; our guides Alex & Stelly did a great job running our group through training, then negotiating the zips, rappel, & rope bridges. They both had an easygoing charm and good humor that complemented the overall experience (in contrast with some tour-guide types who are overly chatty, or quiet to the point of seeming inhospitable). The scenery was fantastic, and we were blessed with good cool weather. The experience from booking through final review/purchase of (very reasonably priced) photos was fun and user-friendly. We'd definitely recommend the tour for anyone traveling the Denali area and looking for a fun short outing with up-close views of the Alaskan rainforest.
