Free admission to Prince William Forest Park, part of the National Park Service. Fee-free days provide a great opportunity to visit a new place or an old favorite. They will give both first time and repeat visitors a good reason to spend time in our national parks. National Public Lands Day is the largest, single-day volunteer effort on behalf of parks and other public lands in the United States of America. The fee wavier does not cover expanded amenities or users fees for such things as camping.
