Welcome to Haunted Hollow, Western Pennsylvania’s Premier Haunted Attraction. Located off the PA Turnpike near Somerset, PA, (Somerset County) and is about an hour from Pittsburgh, PA. Haunted Hollow is a Haunted Attraction that features unique attractions you can’t experience anywhere else. It’s raw and authentic, from the dark hallways of an actual circa 1800's farmhouse to the blood red color of the acid mine drainage, the putrid, rotting smell of the swamp gases and wagon rides across desolate, moonlit fields.
