John D. MacArthur Beach State Park
John D. MacArthur Beach State Park, named for John D. MacArthur whose Foundation donated a portion of the land for its construction in the 1970s, is located on and just north of Singer Island, Florida in North Palm Beach, Florida.
The park was first opened to the public in 1989. It covers 438 acres (1.8 km2) on land and underwater, including an estuary crossed by a 1,600-foot (490 m) boardwalk, and Munyon Island (named after James Munyon), a wilderness isle in the Intracoastal Waterway that was home to the lavish Hygeia Hotel at the turn of the twentieth century. The hotel burned to the ground in 1917.
Hiking trails and pavilions are open for public use on Munyon Island, which is accessible only by kayak or boat. One section of the park was popularly known as Air Force Beach from the early 1940s until the renaming of the park because it was used by Palm Beach Air Force Base personnel. Nude bathing officially ended with the state's takeover of the park in 1982.
MacArthur Beach is a nesting ground for rare sea turtles, including the threatened loggerhead, the endangered green sea turtle, and occasionally the rare leatherback.
John D. MacArthur Beach State Park occupies a particular place in the imagination of American public lands. As a State Park in Florida, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.
The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
