What an incredible experience! Ken and Derek (ask for them if you can) were so patient and personable. They were our guides and fellow zip-liners. Just two of the funniest and friendliest people you’ll ever meet. As for the lines: they totally prepared us for the increasingly long and high lines. 5 lines: increasing in length and altitude, all over incredibly beautiful vistas. If you have a small group, ask about the “Mary Poppins” experience on the 4th line as it is a long but mostly straight route. You can slow down and take your time hanging 150 feet over gorgeous country. Yes, they show you how to do it if you like. And you can stop and just hang, look and maybe pray. Or you can just rocket across. Your call. Our group consisted of a 12 year old “daredevil girl”, a 17 year old “wanna see it all” young man, and a 46 year old “I can totally probably do this” man (me). And every one of us just loved it. Absolute highlight of our Colorado vacation. Just. Do. It.
