Grotto della Poesia, Salento, Italy
Translated as "Cave of Poetry," this 100ft-wide natural sinkhole in Italy's Salento Peninsula inspires awe. Dive from limestone cliffs into crystal-clear cyan waters, then swim under the archway to the Adriatic Sea. Visit early in summer to beat crowds; off-season, enjoy solitude with seabirds. Nearby, explore Grotto della Poesia Piccola with its ancient inscriptions and other archaeological sites on the peninsula's east side (the "heel of Italy's boot").
Queen’s Baths, Eleuthera, Bahamas
On laid-back Eleuthera, hike the rocky hillside to the Queen’s Baths—shallow, sun-warmed tidal pools also called "hot tubs." Time your visit for low or mid-tide to relax, splash, and hunt shells while the Atlantic roars below. Just 0.5 miles away, the Glass Window Bridge showcases the dramatic clash of choppy Atlantic and calm Caribbean waters.
Tunnels Beaches, Devon, UK
Traverse 19th-century hand-hewn cliff tunnels by Welsh miners to reach Devon's hidden beaches. At the former "ladies beach" (now coed), a tidal pool forms three hours before and after low tide, retained by a boulder-and-mortar wall. Victorian-era bathing machines once preserved modesty here; earlier, smugglers hid in the cliffs. Expect classic English pebble beaches—slippery, cool, and charming.
To Sua Ocean Trench, ‘Upolu Island, Samoa
This emerald swimming hole on Samoa’s ‘Upolu Island resembles a giant's eye amid lava fields. Descend a towering wooden ladder—or jump—into 30m-deep, fish-filled waters fed by an underwater lava tunnel to the South Pacific. Watch for undertow; skilled divers can explore the passage. Lush jungle edges give way to seaside gardens, picnic spots, and a small beach.
Bondi Icebergs Pool, Sydney, Australia
Perched above the Tasman Sea at Sydney's iconic Bondi Beach, these century-old concrete pools draw swimmers worldwide. Public lap and kiddie pools welcome all; Icebergs club membership requires five years of winter swims (three Sundays per month). Colder than the sea, waves may crash in during storms for an exhilarating challenge.
Piscinas das Marés, near Porto, Portugal
Dive into a national monument: the 1960s saltwater pools at Leça da Palmeira beach, designed by architect Álvaro Siza Vieira. Carved into rock north of Porto, they offer invigorating swims. Afterward, stroll to his Boa Nova Tea House for Michelin-starred dining with panoramic Atlantic views.
Porto de Galinhas, near Recife, Brazil
Brazil's beach paradise shines with turquoise natural pools beyond its white sands, reachable by traditional jangada sailboats (R$25/person). Formed by reefs, they're perfect for snorkeling. For action, head south to Pontal de Maracaípe for wind- and kitesurfing.
Sea Point Pavilion, Cape Town, South Africa
Cape Town's Sea Point Pavilion buzzes with summer energy facing the Atlantic. Enjoy saltwater lap, diving, and kiddie pools—some ocean-fed. Picnic on the lawns under Lion’s Head with vendor refreshments. Shark-free and scenic, it's a public pool standout.
