Did you ever wonder how this lovely valley may have gotten its name? What did it look like in the 1800’s? Join a park guide to explore some unique geology along Hell Run as we hike to the waterfall and back. The geology of this area led to the iron industry and lime kiln. Although the trail is fairly easy, wear sturdy shoes and dress for the outdoors. The Hell’s Hollow parking lot on Shaffer Road is about four miles south of the Sheetz on 422 & 388 .
