The Captain John Smith Chesapeake National Historic Trail is a series of water routes extending approximately 3,000 miles along the Chesapeake Bay, the nation's largest estuary. These historic routes trace the 1607–1609 voyages of Captain John Smith as he charted the land and waterways of the Chesapeake. It meanders along the shoreline of Douglas Point, Maryland, where the BLM manages the historic 18th century Chiles home site in partnership with the National Park Service. Paddlers may rest at the Blue Bay water stop and enjoy picnic facilities. This stop also provides access to the Chiles site, and is a trailhead for the Potomac Heritage National Scenic Trail as it crosses Douglas Point. National Historic Trails closely follow a historic trail or route of travel of national significance. This congressional designation identifies and protects historic routes, historic remnants, and artifacts for public use and enjoyment.
