What Is Camp Murphy?
The mountain bike trails at Jonathan Dickinson State Park are formally known as the Camp Murphy Off-Road Bicycle Trail System. The name traces back to 1942, when the site served as a top-secret U.S. Army Signal Corps training base for radar operations during World War II. The base was decommissioned in 1947, and the land became a Florida state park in 1950.
Today, the former military grounds host one of Southeast Florida’s most popular off-road cycling destinations. Remnants of the old base, concrete foundations, earthworks, and overgrown structures are visible along several trails, adding a distinct historical layer to the riding experience.
