John D. MacArthur Beach State Park was established in 1989 to protect a diverse and undisturbed subtropical coastal habitat from development. The 478 acre preserve, extending from Lake Worth Lagoon to the beach, is the only state park in Palm Beach County, geographically Florida's largest, and among the top ten fastest growing counties in the nation.
Park visitors can participate in a variety of recreational activities, including kayaking, fishing, bird-watching, and snorkeling. Programs are provided to school groups, as well as the general public, on a broad range of natural history subjects.
