Patuxent River Park – Jug Bay Natural Area

16000 Croom Airport Road, Upper Marlboro, MD 20772
(301) 627-6074

Patuxent River Park is a string of park properties along the Prince George’s side of the Patuxent River, operated by the Prince George’s County Department of Parks and Recreation/Maryland-National Capitol Parks and Planning Commission. The Patuxent is the longest river located entirely within the state of Maryland, and a portion forms the boundary between Prince George’s and Anne Arundel and Calvert Counties. At the northern end of Prince George’s County, the river is just a narrow stream, but below Route 4 the river widens to an impressive tidal channel. The river as a whole is an important migration corridor and its banks hold pristine habitat.  Patuxent River Park provides significant protection to this habitat.

Jug Bay Natural Area refers to an extensive area on the Prince George’s side of the river that has been set aside with special protections and limited development. (Note that the Jug Bay Wetlands Sanctuary is on the opposite shore, in Anne Arundel County; see The “Jug Bay” itself is an expanded section of the river where it is about a half-mile wide. The convoluted shoreline is bordered by brackish marsh and inlets, with extensive wild rice beds that form ideal habitat for waterfowl and other marsh birds.  The Jug Bay Natural Area includes Park Headquarters and Visitor Center; restrooms; boat launch and canoe/kayak rental at Jackson Landing;  trailheads for the Jug Bay Natural Area and Black Walnut Study Area; the Rural Life Museum; a pollinator garden; observation platform overlooking the river; habitats include tidal marshes, non-tidal wetlands, and hardwood forests.  To reach Jackson’s Landing via navigation system, enter 84 McClure Road, Upper Marlboro, MD 20772.

Also within the Jug Bay Natural Area, Selby’s Landing (16000 Croom Airport Road, Upper Marlboro, MD 20772) has a boat launch; trailheads; The habitats at the Selby’s Landing area include tidal marshes; non-tidal wetlands; cultivated fields; grassy fields; mixed forests; numerous streams.  The adjacent Croom Airport/Columbia Air Center Historical Site features a historic display of the first African-American flying field in the US.

The Chesapeake Bay Critical Area Driving Tour is a mostly one-way route that starts at Selby’s Landing and ends at Merkle Wildlife Sanctuary.  See  The entire Driving Tour (that is, from Selby’s Landing to Merkle) is open to cars only on Sundays from 10 am to 3 pm, year-round.
