It’s always a good idea to stay on the trail but in the Hocking Hills, staying on the trail is the law. This is for your safety and the protection of the natural environment. Falling off a cliff top really puts a damper on a vacation. Stay alert and follow the directional signs along the trails. And, as inviting as the pool at the base of the waterfall looks, no swimming, for your safely as well as the aquatic creatures living there.
