John D. MacArthur Beach State Park

Nestled on an Atlantic Ocean barrier island, John D. MacArthur Beach State Park is the only state park in Palm Beach County. It is an environmental treasure which has been preserved for present and future generations to experience.

With 1.6 miles of pristine beach, swimming, snorkeling, and much more to discover, the possibilities of exploration and fun is endless!

While here, visit the Nature Center and our Beach Outfitters Gift Shop. Discover the amazing plants and animals in the estuary by standup paddle board or kayak. Go on a hike on our nature trails, or have a picnic at our pavilions.

Make sure to take advantage of the many offerings throughout the year: daily nature walk, recreational skills lessons, MacArthur Under Moonlight concerts, school programs, summer camp, and much more.

Open daily, we offer something for everyone! Whatever you choose to do while at the Park, we know you will enjoy the serenity of the Real Florida.
