Basic Information


Prince William Forest Park is a diverse natural and cultural area located near Washington, D.C. The park is 15,000 acres of secondary growth forest. Originally established as Chopawamsic Recreation Demonstration Area (RDA) in 1935. It soon became the model site that future RDA sites were patterned after. The Civilian Conservation Corp constructed 5 cabin camp units to support the RDA program. Today the park still operates the cabins as a way for visitors to enjoy the park.

Camping, hiking, picnicking and bicycling are other ways that visitors enjoy the park.

Park staff encourage visitors to learn all there is to know about Prince William Forest Park. History from the early settlers to modern day include stories that cover Cabin Branch Pyrite mine, Civilian Conservation Corps development, Office of Strategic Services (OSS) use during World War II, and operation of cabin camps enhance the story of the park.

Protection of a large portion of the Quantico Creek Watershed is an important natural function of the park. North and South forks of Quantico Creek flow through the park. A large portion of the headwaters for the North fork of Quantico Creek is located in the park. Headwaters for the South fork of Quantico Creek are located on Marine Corps Base Quantico. Partnerships between Prince William Forest Park and Marine Corps Base Quantico work to manage this vital resource. Both creeks can be enjoyed by walking along park hiking trails.
