Beach

Piñones is a stretch of undeveloped coast just east of San Juan where a paved bike path and long wooden boardwalk run between the mangroves and the sea. Renting bikes and riding it is a genuinely good family morning - flat, shaded in stretches, with beaches and lookouts to stop at. The other half of Piñones is the food: a line of open-air kiosks cooking alcapurrias, bacalaítos and pinchos over charcoal, which is the best casual eating near San Juan and a real part of the island’s Afro-Puerto Rican culture. The Atlantic here has strong currents; swim only where locals are swimming.

Buyé is small, sheltered and shallow, with coconut palms growing close enough to the sand to give real shade, which is rarer than it should be. The water is clear and stays waist-deep a long way out with very little wave action, so it is a genuinely relaxing beach with toddlers. Local families use it heavily at weekends and there is a modest food kiosk scene; midweek it can be almost empty. Facilities are limited. It pairs naturally with Playa Sucia and the Cabo Rojo salt flats for a day on the south-west corner of the island.

Jobos splits neatly in two, which is why it works for a family with mixed ages. The western end has the surf break that made Isabela a surfing town, with schools running beginner lessons through the calmer months. The eastern end is protected by a limestone shelf that creates shallow pools and calm water where small children can potter about safely while everyone else is in the waves. Above the beach the rock is undercut into arches and a blowhole. Food kiosks and surf shops line the road behind. Winter brings serious swell that closes the whole bay to casual swimming.

Playa Sucia sits at the very corner of Puerto Rico, a crescent of pale sand enclosed by cliffs, with water that is usually calm and remarkably clear. The name means dirty beach and refers to seaweed that drifts in on some winds, not to the water. Above it a short uphill walk on exposed limestone leads to the Los Morrillos lighthouse and cliff edges that drop straight to the sea - spectacular, and completely unfenced, so young children need holding. Nearby are the pink salt flats of the Cabo Rojo salinas and a birding boardwalk. Bring everything; there are no facilities.

Puerto Rico is the easiest Caribbean trip an American family can take and the one most people plan badly. It is a domestic flight with no passport, dollars, and your normal phone plan — and then people book San Juan for a week and see a fort. This is four days built around the one thing you cannot reschedule: the bioluminescent bay. Plan the trip around the moon, not the weather The bio bays work by dinoflagellates flashing when the water is disturbed, and what kills the effect is not cloud or rain — it is moonlight. Tours run around the new moon and are thin to useless near a full one. Some operators will not run at all. ...

Red Reef put limestone boulders in shallow water close to shore, and the result is a reef you can swim to in under a minute with fish life that punches well above the depth - angelfish, parrotfish, snapper and often a green sea turtle grazing. Because it is only a few feet deep it suits swimmers who are competent but not strong, and you can stand between looks. There are two reef sections, north and south of the lifeguard stands. The Gumbo Limbo Nature Center is across the road and runs a sea turtle rehabilitation facility worth pairing with the swim.

Sapphire combines things that usually do not come together: a genuinely good reef within easy swimming distance at Pettyklip Point, and a broad shallow sandy stretch in the middle where small children can play safely. The snorkelling holds turtles, rays and reef fish. Trade winds funnel through here, which is why windsurfers and kiteboarders use it and why afternoons get choppy - mornings are noticeably calmer. There is a beach bar, watersports rentals and a marina alongside. Public access is via the resort, which is legal and normal in the USVI, where all beaches are public.

The inlet concentrates fish moving between the Indian River Lagoon and the Atlantic, which makes the north jetty the busiest and most productive shore fishing platform in the state - snook, redfish, tarpon and Spanish mackerel all run through here. It is a real walkway with railings rather than a scramble, so children can fish it safely. On the lagoon side there is a protected shallow beach for swimming. The north side has the best surf break on the Florida east coast. Two small museums sit within the park - the McLarty Treasure Museum on the 1715 Spanish fleet wrecked off this coast, and the Sebastian Fishing Museum. A bait and tackle shop opens daily except Wednesdays. Note that bridge construction on the highway began in 2026 and can affect the campground entrance and reservations, so confirm before booking a site.

Siesta Key’s sand is almost pure quartz rather than crushed shell, which makes it startlingly white and - the part that matters with children - cool enough to walk on barefoot at midday in summer when every other beach is unbearable. The Gulf here shelves very gradually and is usually flat, so small kids can wade a long way safely. The main public beach has a large free lot, lifeguards, a playground, concessions and shaded pavilions. The lot fills by mid-morning in season and the overflow parking is a walk.

Sombrero is the middle Keys’ family beach and it is free, which in this stretch of Florida is worth saying twice. The sand is soft, the water stays shallow a long way out, and unlike most Keys beaches there are mature palms giving genuine shade over the picnic tables. There is a playground, clean restrooms and a volleyball court. Loggerhead turtles nest along here in summer, and marked nests appear on the sand. It is a good midpoint stop breaking up the drive between Key Largo and Key West.

The rock jetties at St. Andrews create a protected pool on the Gulf side where the water stays flat when the open beach is rough, and it holds fish - sheepshead, spadefish, small rays - close enough in that a child in a mask can see them standing chest-deep. That combination is uncommon on the Panhandle, where most beaches are beautiful but empty of anything to look at underwater. There is a second calmer beach on the lagoon side for younger kids, plus a campground, and a shuttle runs across to undeveloped Shell Island in season.

The eastern end of St. George Island is state park, which means nine miles of dune and beach with no buildings at all. Walk ten minutes from the parking area and you will have sand to yourself even in July, which is the opposite of most Florida beaches in summer. The Gulf side has gentle surf; the bay side is flat and warm and better for toddlers. Shelling is very good, particularly after a storm. Facilities are limited to a few pavilions and restrooms, and the nearest shop is back across the bridge, so this is a pack-everything destination.

Sun Bay is a public balneario, which means facilities - restrooms, showers, shelters, a large parking area - attached to a beach that on most days is close to empty. The bay is broad and shallow with very little wave action, so it suits small children, and the sand runs for over a mile so you can always walk away from whoever else is there. Vieques’s free-roaming horses graze the grass behind the beach and wander onto the sand, which is one of those things children do not forget. Camping is permitted with a permit. It is the easiest beach on the island to reach with a hire car.

Tamarindo is not much of a sunbathing beach - narrow, some rock, modest sand - and that is not why anyone comes. Just offshore the bottom is turtle grass, and green sea turtles graze it reliably enough that a morning snorkel here is close to a guaranteed encounter. They are unbothered by swimmers who keep their distance, and the water is shallow and generally calm. There is also decent reef towards Luis Peña Cay. There are no facilities at all, so bring water and gear. Regulations require keeping a respectful distance from turtles; do not touch or chase.

Trunk Bay is the beach that appears on every US Virgin Islands poster, and unusually it earns it. The underwater trail is the reason to bring children: a marked route over the reef with plaques anchored to the seabed naming the corals and fish as you pass, in water shallow and calm enough that a competent young swimmer can follow it without stress. Facilities are unusually good for the national park - showers, restrooms, snorkel rental, a snack bar. It is the busiest beach on St. John, so cruise ship days are worth avoiding entirely; check the Charlotte Amalie schedule before choosing your day.

A Forest Service campground in the Ouachita National Forest built around a small lake with a sandy swimming beach. The setting is classic national forest: tall pines, well-spaced sites, a lake loop trail kids can walk on their own, and no commercial development in sight. There is a separate equestrian camping area, so horse trailers do not end up parked next to family tents. Facilities are simpler than a state park, which keeps both the cost and the crowds down.

A state campground on a bluff above Schroon Lake with a swimming beach at the bottom of the hill and a boat launch nearby. Schroon Lake sits far enough north of Lake George to be much quieter, but it is right off the Northway, which makes it one of the easiest Adirondack campgrounds to reach from downstate. The village has a beach, an ice cream stand and a summer band concert series that kids enjoy more than they expect to. Sites are wooded and the lake views from the bluff are excellent.

A beach day with one kid is a bag. A beach day with a four-year-old and a nine-year-old is a logistics problem, because they need different water, different gear, and different amounts of your attention. We went through the packing notes on all 72 swimming adventures in our database - 53 have detailed notes - and pulled out what actually gets recommended and, more usefully, why. Some of it is obvious. Some of it is a genuine safety signal hiding in plain sight. ...

A state campground on the southeastern shore of Raquette Lake with one of the best swimming beaches in the Adirondack Park: a long sandy crescent with a gradual entry that suits toddlers as well as teenagers. Sites sit back in tall pines behind the beach and a boat launch gives access to one of the largest natural lakes in the park. It is a straightforward, old-fashioned family campground where the day plan is usually just the beach. The village store at Raquette Lake covers basic supplies.

A small state park on the west branch of Keuka Lake with campsites split between an open lakeside area and a shaded wooded loop, plus a swimming beach and a boat launch. Keuka is the quietest of the big Finger Lakes and the least crowded to swim in, and the campground has a genuinely relaxed feel. The bluff road above the park has some of the best lake views in the region, and Hammondsport at the south end has a walkable village square with ice cream and the Glenn Curtiss aviation museum.
