There’s something magical about slipping into crystal-clear water that nature carved from solid rock over thousands of years. Natural swimming pools offer experiences that no chlorinated facility can match – from the thrill of jumping into deep emerald waters surrounded by towering cliffs to the peaceful sensation of floating in warm springs fed by underground thermal sources.
These geological wonders provide perfect swimming conditions while showcasing some of the world’s most stunning landscapes. Whether formed by waterfalls, volcanic activity, or ancient erosion patterns, each natural pool offers unique water temperatures, mineral content, and scenic backdrops that make every swim feel like a discovery.
Here are 14 natural pools where you can experience swimming in some of the planet’s most beautiful and pristine aquatic environments.
Blue Lagoon, Iceland
This geothermal spa sits in a lava field on Iceland’s Reykjanes Peninsula, where superheated seawater creates a milky blue pool that maintains temperatures between 98 and 102 degrees Fahrenheit year-round. The water contains high concentrations of silica, algae, and minerals that are said to have healing properties for skin conditions, though most visitors simply enjoy the surreal experience of soaking in warm water while surrounded by black volcanic rock.
Steam rises constantly from the surface, creating an otherworldly atmosphere that feels particularly magical during Iceland’s long winter nights. The facility has been developed with modern amenities, but the pool itself remains a natural wonder where you can swim in comfort regardless of the weather outside.
Hamilton Pool, Texas
This collapsed underground river creates a perfect swimming hole where a 50-foot waterfall drops into a jade-green pool surrounded by limestone cliffs and hanging gardens. The grotto formed when the dome of an underground river collapsed thousands of years ago, creating a natural amphitheater that stays cool even during Texas summers.
Massive stalactites hang from the ceiling like ancient chandeliers, while ferns and moss grow in the perpetual mist created by the waterfall. The pool maintains a constant temperature in the mid-70s and reaches depths of about 25 feet, making it perfect for both swimming and diving from the surrounding rocks.
Devil’s Pool, Zambia
Located at the edge of Victoria Falls, this natural rock pool allows swimmers to literally hang over one of the world’s largest waterfalls during the dry season when water levels drop enough to create a safe swimming area. The rock barrier that forms the pool edge sits just feet from the 350-foot drop into the Zambezi River below, creating one of the world’s most thrilling swimming experiences.
Local guides lead swimmers to the pool via a route that requires scrambling over slippery rocks, adding to the adventure aspect of reaching this unique swimming spot. The powerful current of the Zambezi River creates a natural infinity pool effect where swimmers can float right up to the edge while feeling the thunderous power of Victoria Falls just beyond the rock wall.

Havasu Falls Pool, Arizona
Deep in the Grand Canyon, this turquoise pool sits at the base of a 100-foot waterfall that cascades over red rock cliffs, creating one of the most photographed swimming spots in the American Southwest. The water gets its distinctive blue-green color from high mineral content, particularly calcium carbonate, that also creates the terraced rock formations surrounding the pool.
The pool maintains a refreshing temperature year-round, typically in the 70s, making it a perfect respite from the desert heat above. Reaching Havasu Falls requires an 8-mile hike through tribal land, but the reward is swimming in pristine waters that feel like a hidden oasis in the middle of one of America’s most dramatic desert landscapes.
Fairy Pools, Scotland
A series of crystal-clear pools connected by waterfalls flow down from the Cuillin Mountains on the Isle of Skye, creating a chain of natural swimming holes with water so clear you can see every pebble on the bottom. The pools form along the Brittle River as it cascades down the mountainside, with each pool offering different depths and swimming conditions.
Water temperatures remain quite cold year-round, typically in the 50s and 60s, but the stunning Highland scenery and incredibly pure water make the chilly dip worthwhile.
Cenote Dos Ojos, Mexico
This underwater cave system on Mexico’s Riviera Maya features two connected pools with water so clear that swimming feels like floating through liquid glass. The cenotes formed when limestone bedrock collapsed to reveal underground rivers that have been flowing for thousands of years, creating perfectly clear freshwater pools in the middle of a tropical jungle.
Water temperatures remain constant at about 77 degrees year-round, making swimming comfortable regardless of season or weather above ground. The pools connect to extensive underwater cave systems that attract divers from around the world, but surface swimming provides its own magical experience as tropical fish sometimes swim alongside you in the crystal-clear water.

Sliding Rock, North Carolina
This natural water slide carved from granite creates a 60-foot slippery slope that ends in a deep swimming hole, offering both thrills and refreshing mountain water in the heart of the Blue Ridge Mountains. Spring water flows constantly over the smooth rock face, creating a fast but safe ride that ends with a splash into the 7-foot-deep pool below.
The water maintains temperatures in the 50s and 60s even during summer, providing a shocking but invigorating contrast to the warm mountain air. Lifeguards are on duty during peak season, making this one of the few natural swimming spots with professional safety oversight while maintaining its wild, unprocessed character.
Kuang Si Falls, Laos
These multi-tiered waterfalls create a series of turquoise pools that cascade down limestone formations through dense tropical forest, with each level offering different swimming experiences from shallow wading pools to deep swimming areas. The water gets its distinctive blue color from minerals dissolved from the limestone, creating pools that look almost artificially colored against the green jungle backdrop.
Lower pools maintain warmer temperatures, perfect for leisurely swimming, while higher pools offer cooler water and more dramatic cliff-jumping opportunities.
Tat Kuang Si Bear Rescue Centre Pools, Laos
Located near the famous Kuang Si Falls, these lesser-known pools offer more secluded swimming experiences in the same stunning turquoise waters without the crowds that gather at the main falls. The pools form part of the same limestone spring system but provide more intimate swimming areas surrounded by dense jungle and accessed by smaller trails.
Water temperatures remain comfortably warm year-round, and the pools range from shallow areas perfect for relaxing to deeper sections suitable for proper swimming. The setting feels completely wild and untouched, with only the sound of flowing water and tropical birds to accompany your swim.

Emerald Pool, Utah
Located in Zion National Park, this spring-fed pool sits at the base of a waterfall that drops from the red rock cliffs above, creating a swimming hole that perfectly captures the essence of the American Southwest. The pool gets its name from the green algae that sometimes grows on the rocks, though the water itself remains clear and refreshing.
Swimming is technically not allowed in the main Emerald Pool, but similar formations throughout southern Utah provide legal swimming opportunities in comparable settings. The surrounding red rock formations and desert vegetation create a uniquely American swimming environment that showcases the beauty of the Colorado Plateau.
Jacobs Well, Texas
This artesian spring creates a deep, clear swimming hole that stays at a constant 68-70 degrees year-round, fed by underground water sources that maintain perfect swimming conditions regardless of surface weather. The spring produces thousands of gallons of water per minute, creating a swimming experience in water that’s been filtered through limestone for decades before emerging crystal clear.
The pool reaches depths of over 30 feet, making it popular with divers as well as swimmers who enjoy the clarity and consistent temperature. Cypress trees around the spring provide shade and create a peaceful swimming environment that feels far removed from the Texas heat.
