Chastain Beach occupies a narrow slice of Hutchinson Island where A1A bends away from the resort strips and into a neighborhood of low-slung beach cottages and weathered wooden fences. You park on the shoulder beneath a canopy of twisted Australian pines, their needles carpeting the sand in rust-colored drifts. The beach itself stretches wide and flat at low tide, revealing tide pools pocked with periwinkles and the occasional horseshoe crab trundling toward the surf.
“It's where Stuart residents go when they want the island to themselves, no boardwalk, no fanfare—just sand, sky, and a working waterfront horizon.”

The water here runs a green-gray most of the year, warm and gentle, with sandbars that shift after each northeaster. Gulls and terns work the shallows in the morning; by midday, you'll have long stretches to yourself, save for the occasional dog walker or someone combing the wrack line for lettered olives. The absence of lifeguard stands and concession huts means you bring what you need—and leave when you're ready.
Sunset is the beach's quiet crescendo. The sky ignites in bands of coral and violet, silhouetting the inlet markers and the shrimp boats heading back to port. Locals know to arrive around 6 p.m., cooler in hand, and settle in for the show. There's no applause when the sun finally dips, just the sound of waves and the occasional clink of beer bottles—a ritual as dependable as the tides.
