We have met friends in this area for many years, coming in from Raleigh, NC and Cleveland, OH to the perfect half way point. This is the second time the adults and experienced the gravity zip-lines and the third time for the kids. What an amazing experience! You are so high above the world, looking around at the beautiful area, or simply balling up and racing as fast as you can against your neighbor on their line! You lose track of just how high and fast you are moving through the air! My favorite was seeing my shadow dance below me on the ground as I went. This is an amazing experience that everyone should try. The Treetops trip is just as fun, but in a different way. You have more of a feeling of being in nature, zipping through the trees from platform to platform. Next year, I plan to do both!
