Parkers Creek Watershed Nature Preserve protects one of the last remaining pristine watersheds on the western shore of the Chesapeake Bay. Located just north of Calvert Cliffs in southern Maryland, nearly 3,000 acres are conserved and managed here by the American Chestnut Land Trust.

The brackish tidal stream known as Parkers Creek meanders through salt marsh to the Bay's shoreline. Visitors to the preserve may walk more than 15 miles of trails, exploring hardwood forests, farmland, wetlands, salt marsh, Chesapeake shoreline and the Creek itself. Guided canoe trips of the creek are also offered.
