You'll need an ATV to visit this one. It's in the Hatfield-McCoy Trail System on the Rockhouse section
It's on trail 13 of the Rockhouse section of the Hatfield McCoy trail system. This waterfall was reported and photographed by Sara Szymanski Foss on the West Virginia Waterfalls Facebook group.
I do not have any GPS coordinates for this waterfall, but it is listed on the trail map which you can see here. I've marked it on the map in large letters for you.
