My 3 kids (11, 9, 9) and I did the 6 zipline adventure the morning of July 25th. We utilized the transportation to pick us up and drop us back at our hotel in downtown Denver. All around great experience. My kids ziplined a few years ago but weren't heavy enough so had to tandem. WhenI booked, I was told they could do some, but probably not all of the lines by themselves. They did the first line tandem, but then the guides said if they wanted to go alone, they would make it happen! My kids were so excited! The guides only had to go out twice (once for each of my 9 year olds) to help bring them in about 10-20 feet. It was thrilling, yet everyone felt safe. Highly recommend! The photo and go pro package was reasonable too!
