The rules for all of them
No lifeguard, no bathroom, no shade you did not bring, no cell signal, and nobody to hear you. Go with someone, go early, carry more water than you think, wear shoes that grip wet rock, and read the rip currents page first: a secluded beach on the Atlantic side is a surf beach with no one watching. On the islands and the refuges, the land belongs to the US Fish and Wildlife Service or the DRNA: no camping, no fires, no vehicles on sand, nothing collected, dogs leashed, and areas marked closed are closed by land and by sea. Turtle beaches close in nesting season. USFWS: visiting the Vieques refuge
Vieques
- Playa Negra
Black volcanic sand, two miles of it, reached down a quebrada that runs with water after rain, with room for about two cars at the sign. The catch: it is not a swimming beach. Rip currents, no lifeguard, and at high tide the walk turns into a rock scramble. Go for the sand and the walk, in grippy shoes, not alone. Vieques.com: Playa Negra
- Playa Escondida
One of the farthest beaches on the reserve, narrow, with little sand and almost no parking, which is why it is empty while everyone goes to La Chiva. Bathrooms are back at the refuge gate. The catch: a weak signal and a long way from help.
- Media Luna and Navío
Media Luna is a calm, shallow cove you can wade 50 feet into, the one secluded beach here that suits small children. Navío, past it, has cliffs, hidden caves at the ends, and playful waves for boogie boards. The catch: in the rainy season the road to Navío floods, and there is nothing past Sun Bay's gate: no toilets, no water, no lifeguard. Life vests on the kids at Navío.

Culebra
- Zoni
Steps from the road to two miles of sand facing Culebrita and St. Thomas, with caves for shade and almost nobody on it. The catch: no bathrooms, no kiosk, no lot, and leatherback nests from April to June, when parts close. Sunrise here is the best hour on the island. Discover Puerto Rico: Zoni
- Brava
The island's biggest surf and a nesting beach that closes April to June and after sunset in season. The catch is all of that: an unmarked trail, no swimming, and a ranger if you are there at the wrong time.
- Resaca
A hard walk through mangrove and boulder forest to a beach with reef right up to the sand, which rules out swimming, and turtles nesting behind you. For the hike and the solitude only.
- Carlos Rosario
Narrow sand between reef and boulders, inside the Luis Peña Channel reserve, and the best snorkel you can walk to in Puerto Rico. The catch: everything you bring comes back up the ridge in the afternoon heat, and the reef is protected, so look and do not touch. Moon: Culebra's beaches
- Culebrita and Playa Tortuga
An islet with a ruined 1886 lighthouse, tide pools called the jacuzzis, and a crescent of sand where green turtles nest. H2O, Gammy's and Cayo Norte run it from the Dewey waterfront; the boats leave mid-morning and will not wait for a late ferry, you wade out for the pickup, and the captain decides each morning whether the sea allows it. The catch: no shade, no facilities, the lighthouse is off limits, and the beach called Trash Beach has an undertow. The Traveler: Culebrita water taxis, October 2026
Fajardo and the cays
- Playa Escondida and Playa Colorá
Walk past the end of the balneario and the trail through the reserve comes out on two beaches with soft waves and nobody on them; Colorá is five minutes farther. The catch: a 55-year-old visitor from Ohio drowned at Escondida in March 2023 during a dangerous surf warning. Calm looking is not calm. Check the forecast and swim at Seven Seas if it says High. El Nuevo Día, March 2023
- Icacos
An uninhabited cay 15 minutes off Fajardo with palms and sea grape on one side and clear water all around, inside the La Cordillera reserve. Water taxis take 6 to 12 people, some cash only; the catamarans from Puerto del Rey and Villa Marina come for the day. The catch: no bathroom, no shelter, no vendors, no lifeguard, rips on the outside, and the last boat is the last boat. Weekdays are quiet. Discover Puerto Rico: Icacos
The southwest
- Playa Sucia (La Playuela)
The crescent below the Los Morrillos lighthouse, with the salt flats and the cliffs above it. Gentle waves most of the time, with the usual caution in the deeper water, no facilities, no lifeguard, and no barriers on the cliff edge. The catch: locals fill it on weekends and holidays, seaweed drifts in all winter, which is how it got the name, and the sargassum found it in 2026. The lighthouse is open Wednesday to Sunday; the salt flats and the lighthouse both close Monday. Go on a weekday morning. Discover Puerto Rico: Cabo Rojo
- Gilligan's Island, Isla Ballena and Playa Ballena
Gilligan's is a mangrove cay with warm, waist-deep water for small children, and it is not secluded on a weekend. Ask the boatman for Isla Ballena instead, a couple of dollars more and closed to the public on Mondays, or walk the dry forest trail to Playa Ballena on the mainland, which has no facilities and no crowd. Kayaks rent at Copamarina and Mary Lee's for about $20 an hour. Discover Puerto Rico: Guánica
- Tamarindo, Guánica
A reserve beach at the end of the pavement, with parking at the road end and nothing else. Different from the Tamarindo on Culebra.
The northwest
- Peña Blanca (the Wishing Well)
Limestone alcoves for shade, hammocks between the palms, snorkeling in summer. The catch: no official lot, a short rugged walk, no bathrooms, no lifeguard, and from autumn through spring the surf comes up and the rocks have taken people. May to August only. Discover Puerto Rico: beaches for relaxing
- Survival Beach
Named for a reality show that filmed here and lived up to by the trail, which is easy to lose; a small bridge marks the way. Caves for shade and a beach you will probably have alone. The catch: no source will vouch for the swimming, and that means do not. The walk and the rocks are the trip. AFAR: Survival Beach
- Shacks, Isabela
A reef lagoon with turtles and, some summers, a manatee, but a strong current and a rocky coral bottom. Snorkel it on a flat summer day with a buddy. Jobos, next door, is on the family beaches page as a warning, not a recommendation.
The southeast
- Punta Tuna, Maunabo
A wetland reserve of mangrove and marsh with marked trails, an observation tower, and a beach that is a turtle nesting refuge guarded by the ATMAR volunteers since 2001. Closes at 5. The catch: it is a nesting beach first, with the lights-off, stakes-respected rules of the sea turtles page, and the surf conditions are nobody's promise. Platea PR: Punta Tuna reserve
The ones that need a permit
- Mona Island
A hundred visitors at a time, Sardinera the only camping beach, hunting seasons from December to April when the caves close, alcohol banned, and several hours from a doctor. The charter captains in Joyuda, Boquerón, Mayagüez and Rincón handle the permit. On the treasure page, because that is why people go. DRNA: Mona Island notice
- Luis Peña Channel, Culebra
No fishing of any kind since 1999, anchoring only on the buoys in the southern sand zone, no touching coral, tour operators licensed by the DRNA, and the cay itself open by day only. Luis Peña reserve rules
- Caja de Muertos
Playa Larga is closed for turtles; Pelícano is open and on the family beaches page.
The beaches with lifeguards are on the family beaches page; all of them, with the bio bays and the sargassum, on the beaches page.
