Just an absolutely wonderful experience for the entire family. We loved it so much last year that we had to come back. It's a beautiful day outdoors. The ziplines and bridges of the Mid-mountain tour offer a good jolt of adrenaline but not to the point of being too scary. And the guides are fantastic. Friendly, funny, and VERY focused on safety. They might be peppering the experience with a generous helping of jokes but their attention never wavers from the job at hand. The lines and equipment are also clearly well maintained. Even the staff at the main office are lovely and helpful. I heartily recommend it.
Updated 2021: still Awesome! They've invested and made some nice changes and improvements since we last went. Our tour guides - Liz and Brandon - were fantastic (again)!
