The two-lane road north from Palm Beach yields to a 438-acre preserve where coastal hammock, mangrove wetlands, and dune scrub crowd right up to the tide line. You enter through a nature center built on stilts, then follow a quarter-mile boardwalk that snakes through buttonwood thickets humming with cardinals and geckos rustling the leaf litter. The planks deliver you onto a strand where the sand compresses firm beneath your feet—packed tight by Atlantic swells that roll in gentle but persistent, polishing coquina fragments into peachy dust.

Mornings bring wading birds to the shallows: roseate spoonbills sweeping their bills through the shallows, great blue herons frozen mid-stalk. The swimming area stays calm enough for toddlers, protected by a shallow sandbar a hundred feet out, while snorkelers drift along the reef edge where sergeant majors flash their prison stripes. By late afternoon the western sky ignites behind the mangroves, casting the lagoon in copper and rose—families spread blankets on the upper beach, thermoses of cold brew in hand, waiting for the finale.
This is Palm Beach County's sole state park oceanfront, which means it's tightly managed: parking fills by mid-morning on weekends, and rangers enforce carry-in, carry-out rules with the zeal of backcountry wardens. But that vigilance preserves what development devoured elsewhere—a coastline that still belongs to the fiddler crabs and loggerheads.
