This beloved Pennsylvania resort somehow attracts even more. Lake Raystown Resort actually puts you right on the shore of Raystown Lake in Entriken, Pennsylvania. The resort spans 400 acres of waterfront land, and the lake itself covers between 8,000 and 8,500 surface acres. The Proud Mary Showboat at Lake Raystown Resort offers sightseeing cruises, breakfast cruises, and dinner cruises, each one giving passengers a front-row seat to some of the most scenic water views in Pennsylvania. Raystown Lake itself has its own history worth knowing.
