Effective March 17, 2025: The North Beach restroom at John D. MacArthur Beach State Park is temporarily closed for repairs.
Situated between the Atlantic Ocean and the Lake Worth Lagoon, the park includes 438 acres of natural environments, including seven species of plants and 22 species of animals designated as endangered or threatened.
John D. MacArthur Beach State Park was established in 1989, the only state park in Palm Beach County. The purpose was and is still today to protect a very rare and spectacularly beautiful piece of Florida’s southeast coast.
John D. MacArthur realized this after a university study in the 1970s revealed the biological treasures in this area.
