From the official listing

Overview Oak Ridge Campground is a 100-site, wooded campground located in Prince William Forest Park, 35 miles (56 km) southwest of Washington, DC. The park's land was set aside during the Great Depression, and in 1935 the Civilian Conservation Corps (CCC) began restoring the previously over-farmed acreage, converting it to recreational lands for public use. The CCC built trails, dams and cabins, making the park a wonderful place for recreation and relaxation. Large group camping is not permitted at Oak Ridge Campground. Please read the need to know section for additional information.

Recreation The park offers many Things to Do including hiking, biking, orienteering and fishing. Hikers enjoy exploring the park's 37 miles (60 km) of foot trails.

Bicyclists will find On and Off Road Biking on 21 miles (34 km) of paved roads within the park, including the 12-mile (19 km) Scenic Drive. Minimal traffic and a 25 m.p.h.
