South Mountains NC
Ive gone exploring nude in the river, but its a bit of a hike to get to a secluded spot. We made the strenuous hike to the top of the falls, and then to the nearby campground. From there, there is a short trail upstream. Once the trail disappeared, we dropped trou and hiked upriver for .5-ish miles. There are no marked trails that-a-way, so we felt fairly confident no one would see us. The stream bed is rocky, so I recommend Crocs or good sandals.
