We have had several people tell us GPS brings them via Concord or Route 274 and or Blain New Germantown Road. Do not take either of these roads. PA Route 75 is a full circle. You want to come from the Concord area to Horse Valley Road with a trailer not from the town of East Waterford. Please see MAP below. Set GPS from not the fastest way as it will bring you with your camper on back roads. Hope this helps
