The forested park lies approximately 10 miles (16 km) northeast of Washington, D.C., and is situated just within the Capital Beltway (which bounds the park to the northeast).
The park land was originally intended to form part of the green belt surrounding the city of Greenbelt.
The southern portion was assigned to the National Park Service, thus forming the park, while another section became part of the Henry A. Wallace Beltsville Agricultural Research Center (BARC).
Recreational facilities include a 5.3 mile (8.5 km) mile hiking and equestrian trail, several shorter nature trails, numerous campsites, and three picnic areas.
Nearly all of the park's facilities are located within the larger western portion (the eastern portion has one fire road).
