The redesigned Visitor Center at Prince William Forest Park now focuses on educating visitors about the diversity of the historical and natural aspects of the park. Exhibits showcase the park’s Native American history, its construction in the 1930s by President Roosevelt’s Civilian Conservation Corps, its time as a Recreational Demonstration Area (RDA) camp for poor and inner-city youth, and its occupation by the Office of Strategic Services (OSS) for training during World War II. - The redesigned Visitor Center at Prince William Forest Park now focuses on educating visitors about the diversity of the historical and natural aspects of the park.
