John D. MacArthur Beach State Park was established in 1989. It is the only state park in Palm Beach County! The purpose of this park is 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 1970's revealed the biological treasures in this area. Situated between the Atlantic Ocean and the Lake Worth Lagoon, the park is 438 acres of natural environments, including seven species of plants and twenty-two species of animals designated as endangered or threatened. The Friends of MacArthur Beach State Park has an award-winning Natural Science Education Program where students in Palm Beach County learn about the ecosystems in South Florida while being immersed in them. We will be offering Virtual Field Experiences soon! We also offer a Marine Biology Summer Day Camp where students spend a week as a "MacBeach scientist" all while kayaking, fishing, hiking, snorkeling, making arts and crafts, and participating in many science activities!
