Greenbelt Park is a 1,100-acre National Park Service woodland located 12 miles from downtown Washington, D.C. It is the only National Park unit within the Capital Beltway. The park features 172 campsites available year-round, including specialized sites for tents and recreational vehicles. Visitors have access to nine miles of hiking trails that traverse hardwood forests and stream valleys. The park provides picnic areas with tables and grills situated in shaded, forested settings.
