About This Beach
John D. MacArthur Beach State Park offers the rare combination of an unspoiled tropical coastal habitat in the highly developed Palm Beach area. The beach is reached via a 1,600-foot boardwalk that crosses a picturesque lagoon lined with mangroves. The offshore Anastasia rock reef provides excellent snorkeling opportunities with abundant marine life. The park’s Estuary Trail offers wildlife viewing including osprey nests, herons, and occasionally manatees. The nature center provides educational exhibits and programs.
