About Prince William Forest Park

Prince William Forest Park has been providing recreation and respite for people, and habitat for plants and animals since its founding in the 1930s. Originally named Chopawamsic Recreational Demonstration Area, Prince William Forest Park was an escape from the city for children and families of the Washington, DC area during the great depression. Over two hundred rustic buildings, arranged into cabin camps, housed these children and their families during summer ‘nature’ camps. Over 150 of those cabins still stand today within the 15,000 acres of forest-covered park, now the largest protected natural area in the Washington, D.C., metropolitan area.

The park protects the largest example of eastern piedmont forest in the National Park System. Here you will find northern species such as Hemlock along with southern species such as Poplar and Virginia Pine. The park also protects a large portion of the Quantico Creek and its watershed. Scientists have used the Quantico Creek as a benchmark in water quality for the area.

For those interested in history, Prince William Forest Park also protects and interprets a history that stretches from Native Americans and Early Colonial Life to the Great Depression and World War II. Franklin Roosevelt’s “Tree Army”, the Civilian Conservation Corps (CCC), constructed buildings, roads and lakes here during the 1930’s, including the 5 historic cabin camps. From 1942 to 1945, the United States Office of Strategic Services, forerunner to the CIA, used this land exclusively for the training of spies and radio operators. Since World War II, generations of Americans have spent their first night camping under the stars here at Prince William Forest Park.

Today, groups visiting Prince William Forest Park can use its 37 miles of hiking trails and 21 miles of bicycle-accessible roads and trails to experience this unique natural area and learn about the native Virginia plants and animals. Overnight trips can further student connections to this national treasure through group tent and cabin camping. If you're looking for lessons in history or the natural world, educational opportunities abound in Prince William Forest Park.

Facilities in the Park

Day-Use Facilities

The Prince William Forest Park Visitor Center is a great place to start your visit to the park. Its exhibits house museum artifacts from the park’s history and include hands-on activities for kids of all ages. The visitor center also houses a 30 person classroom with row seating, a large screen television with VCR and the availability of slide presentations. The park orientation video can be viewed here at any time, free of charge and is a great introduction to the park for your students. Contact: 703-221- 7181.
Pine Grove Picnic Area is available on a first-come, first serve basis. Located adjacent to the visitor center and less than 1 mile from the park entrance, this picnic area is the perfect place for a quick picnic lunch on your way into DC. This picnic area has a pavilion, picnic tables, a playground, bathrooms and grills.

The Telegraph Road Picnic Pavilion is a thirty foot by twenty foot roof-covered porous brick pad with twelve picnic tables (six of them wheelchair accessible), six cooking grills and electric outlets. It is adjacent to a comfort station with food-service sinks and flush toilets, and there is easy wheelchair access to the pavilion from the picnic area's 73 parking spaces. There are approximately twenty additional picnic tables scattered throughout the adjoining woods of Telegraph Road Picnic Area, most with its own grill. A short path leads to spacious William's Ballfield (available first come, first served), which is suitable for softball, volleyball, frisbee and other activities.

Telegraph Road Picnic Pavilion and comfort stations are closed for the season from November through Mid-April. The pavilion may be reserved for $80 per day on When not reserved, it is available without charge on a first come, first served basis from 9:00 a.m. to dusk. The park entrance fee is also required, unless you have an educational fee waiver. Please note: the educational fee waiver does NOT waive the cost of the pavilion, just the entrance fee.

Built with funds provided by park fees, the Telegraph Road Picnic Pavilion is a good example of how the National Park Service uses fee monies.

Ticks are common in Prince William Forest Park. They are usually found in grassy and bushy areas in the Spring, Summer and Autumn. Stay on trail and ensure that students have their parents conduct a “tick check” on their clothes, hairline, ankle and foot area when they go home. Individuals attending the park should use insect or tick repellant as recommended by a medical professional.

Poison Ivy is ever-present in Prince William Forest Park. It has shiny leaves in groups of three and grows either as a shrub or on a fuzzy vine. “Leaves of three, let it be” is good advice for students. Wash with soap and water after contact.

Snakes are an essential part of the Prince William Forest Park ecosystem. Do not purposely approach any snakes within the park. If you encounter a snake on a trail, either go around it at a wide circumference or back-track. Snakes often rest on rocks to enjoy the sun, or hide in cool, damp places to stay cool. Please tell your groups not to reach under logs and rocks unless inspecting the area first.
