We had a great time zip lining with Millie and Gigi. They ensured everyone had fun and were safe. The Mountain View is a beautiful bonus. Highly recommend this experience. Bring lots of water with you.

I had the best time doing all 10 ziplines during the sunset! Spectacular views so I recommend calling & asking for them a later time. Every staff member I encountered was super helpful & encouraging. Special shout out to Solei who made the whole experience super seamless, easy, & fun! I'll be back for the Sky Trek this summer!

The is was our second time doing this and it was so fun!! Super safe, and fun! The guides- Katie and Sean- were so friendly and made sure we were safe- also were interested in each of us. There were 2 stops with water. One with candy :) was about 2.5 hours or so.

It was a wonderful experience for us. Our Guides, Jacen and Austin were super, great! However, it was more intense hiking than I thought. But so glad I did it!

Will and Millie did a great job guiding our tour on December 7, 2025. They explained the safety rules and the signals for slowing down. That was the first time doing the zip line for my granddaughter and she really enjoyed it. We really appreciate their expertise in showing us how to do the zip line. Walking through the snow and ice on some of the trails between stations was not fun but we succeeded in getting to the next stop. Thank you Will and Millie!
