Directions: (borrowed from the Botanical Society of Western Pennsylvania). From Pittsburgh, take the Parkway West (I-376) to the Airport Parkway (PA 60). Continue past the airport's exit to exit 9 (Hopewell). Go west (left) on PA 151. Shortly after you cross an iron bridge, you will see an Amerigas facility on the corner. Turn right here onto Cowpath Road. Drive about 0.5 miles to the Beaver County Conservation Center.
