John D. MacArthur Beach State Park in North Palm Beach, near Singer Island and West Palm Beach, preserves 438 acres of coastal and underwater habitat. Named for John D. MacArthur after his foundation donated part of the land in the 1970s, the park opened to the public in 1989. Its estuary and 1,600-foot boardwalk highlight one of the area’s preserved natural landscapes. The park also includes Munyon Island, once the site of the Hygeia Hotel before it burned in 1917 and now reachable only by kayak or boat. The shoreline also carries the legacy of Air Force Beach, while the park remains an important nesting and habitat area for sea turtles and birds.
