Fly Gorge is a deep gorge, with 40-foot cliffs and cascading waterfalls. To get there, you have to park in a nondescript pull-off on Ohio Scenic Byway 7, push your way through a dense wall vegetation and carefully scramble on boulders and slick rock waterboards.
The pull-off for this is just north of Rt. 800 on Rt. 7 just past this historical marker.
