Lime Cay
Port Royal, Kingston Parish, Jamaica

Lime Cay sits about fifteen minutes by boat from Port Royal, at the mouth of Kingston Harbour in Jamaica, a small uninhabited sandbar island that floods partially at high tide and has no facilities of any kind. Sundays bring the biggest local crowds, with Kingston residents mooring boats offshore and bringing their own lunch and drinks for the afternoon.
A genuine local Sunday tradition with real charm to the small boat crossing, though the total lack of facilities and its exposure to weather mean it's worth checking conditions rather than assuming it's always calm.
Bring everything you'll need, and check conditions before heading out, since the cay is exposed and has no lifeguards or services if something goes wrong.
Boats leave from Y-Knot in Port Royal, with round trip rides costing a modest fee and running frequently on request.
Boats land directly on the small beach, and there's no paved path or infrastructure of any kind, just open sand and water.
The dry season from December through April brings calmer seas for the boat crossing, while Jamaica's hurricane season runs June through November and is worth checking before planning a trip out.

Frenchman's Cove
Port Antonio, Portland Parish, Jamaica · Caribbean
Frenchman's Cove sits in San San, just outside Port Antonio in Jamaica's Portland parish, where a shallow, clear river winds down through the resort grounds before spilling out onto a short stretch of fine white sand. Built in 1958 as one of the Caribbean's first all-inclusive resorts, the beach has since shown up in films including Lord of the Flies for its wild, cinematic backdrop.

Boston Bay Beach
Port Antonio, Portland Parish, Jamaica · Caribbean
Boston Bay sits just east of Port Antonio in Jamaica, widely credited as the birthplace of jerk cooking, with jerk huts lining the road behind a beach that also happens to have some of the most consistent surf on the island's north coast. Locals rent boards and give lessons right on the sand, and the annual Jerk Festival draws crowds here every July.

Playa La Vacama
Higuey, La Altagracia, Dominican Republic · Caribbean
Playa La Vacama sits on the northeast coast of the Dominican Republic in La Altagracia province, a quiet, undeveloped stretch of sand that stays well off the radar compared to the resort beaches around Punta Cana. Coconut palms line the shore, and the relative lack of infrastructure is exactly what's kept it from turning into another all-inclusive strip.
