The zip lines are pretty cool. Our daughter wanted to do it for her birthday last year. There are 4-5 levels you can go through. If you try it go to at least level 2 , that's where the real ones start. We only went to level 2 and I really wanna go back and do the whole course.
We stayed in one of the Cabins couple years ago, walked the trails, didn't do the zip lining, the first couple levels might be okay, no way you'd get me up to 4 or 5, that top level is crazy high! Very nice place, had dinner and breakfast in the restaurant there, very good food !
