There’s nothing like the sight of crystal-blue water to make us want to board a plane. When the mercury rises, the urge to dive right into a glimmering turquoise body of water is hard to resist. But while pools are all too common and beaches often get crowded in in hot weather, here's another idea: natural swimming pools. Often more remote and pristine that popular coastal destinations, these bodies of water are hard to resist.

If you're thinking of a vacation, we thought we’d instill some of that “Where in the world is that?” wanderlust in you with these incredible natural swimming pools that you can actually take a dip in around the world. From a death-defying waterfall to a pool that’s Pepto-Bismol pink, these lakes, lagoons, caves, holes, and bays will stun you.

The Devil’s Pool, Victoria Falls, Zimbabwe

Swimming in Zimbabwe’s Devil’s Pool, a small 328-feet-high lagoon abutting Victoria Falls, one of the biggest waterfalls in the world, is the epitome of “living on the edge.” One can only imagine the surrealism of looking down into Victoria Falls—and thankfully there are guides there to ensure you don’t slip.

Jellyfish Lake, Palau, Micronesia

Located on the island of Eil Malk in Palau, Micronesia, Jellyfish Lake is a marine lake filled with millions of golden jellyfish that migrate across the lake daily. Jellyfish do have stinging cells (so avoid them elsewhere), but in this lake, they have no natural predators so they’ve lost their ability to sting. Snorkeling and underwater photography are popular activities.

Fingal’s Cave, Staffa, Scotland

This sea cave on the island in the Inner Hebrides (western archipelago) of Scotland is formed by hexagonally jointed basalt columns within an ancient lava flow (similar to Giant’s Causeway in Northern Ireland). Fingal’s Cave is known for its natural acoustics; thanks to its size and cathedral-like arched roof, the waves echo inside, producing eerie sounds. To access the cave, you can take a local sightseeing cruise to the entrance.

The Great Blue Hole, Belize

About 60 miles off the coast and part of the Belize barrier reef, the Great Blue Hole is an underwater sinkhole that’s home to a number of distinct species of fish and other marine life. Encircled by an island of coral, it has a rich blue color and is close to 1000 feet wide and 400 feet deep—it’s believed to be the largest sinkhole in the world. Snorkeling and diving in it are popular, and it can also be seen from the air.

Havasu Falls, Grand Canyon, Arizona

Located in the Grand Canyon, Arizona, within Native American (Havasupai) tribal lands, Havasu Falls is an oasis in the hot and dry Grand Canyon National Park. It consists of one waterfall chute that drops over a 90- to 100-foot cliff into a large pool. Due to high calcium carbonate content, the water has a vivid blue-green color that contrasts gorgeously with the surrounding red rocks.

The Blue Grotto, Capri, Italy

On the island of Capri in Southern Italy, the Blue Grotto is a sea cave that is illuminated by a magical blue (and sometimes emerald green) light from an above-water opening. It can be accessed by tiny rowboats.

The Dead Sea, Israel and Jordan

Technically, you can’t swim in the Dead Sea, one of the saltiest bodies of water on earth, which is bordered by Israel and Jordan; swimming in it is more like floating. The salt lake has attracted visitors for thousands of years, and the salt and minerals that create the milky blue-green color offer many health and beauty benefits.

Pamakkale, Denizli, Turkey

A natural site in Denizli, Turkey, the city of Pamukkale is marked by terraces of carbonate minerals left by flowing water from hot springs and travertines. The “cotton castle,” as it’s called, has welcomed tourists for thousands of years, and they bathe on its calcareous rocks in the hot, mineral-rich water.

Hidden Beach, Marieta Islands, Mexico

Located in the Marieta Islands a few miles off the coast of Nayarit, Mexico, Hidden Beach is an open, sun-drenched crater that can only be accessed when the tide is low. Technically it’s actually artificial, as it was created by the explosion of a bomb that accidentally landed there during military trials, but nevertheless, it’s a sight to see.

Bioluminescent Bay, Vieques, Puerto Rico

Located in Vieques, Puerto Rico, Bioluminescent Bay is a national natural landmark that lights up at night thanks to microorganisms (dinoflagellate) that glow neon blue when movement occurs in the water. It is a mind-blowing sight, so much so that early Spanish settlers thought the bioluminescence was the work of the devil.

Lake Hillier, Western Australia

A saline lake off the south coast of Western Australia, Lake Hillier is notable for its Pepto-Bismol–pink color, which is suspected to be caused by a type of microalgae found in sea salt fields. Like the Dead Sea, it is safe to swim in, but it can be difficult to reach other than via helicopter or cruise ship.

Crater Lake, Oregon

Famous for its remarkably clear, deep blue water, Crater Lake in South Central Oregon was formed by the collapse of volcano Mount Mazama more than 7700 years ago. The lake is filled by snow and rainfall—there are no rivers flowing in or out of it. There are also two islands in the lake.

Öschinensee Lake, Lötschberg, Switzerland

A pristine mountain lake fed by glacial brooks, Öschinensee Lake in the Lötschberg region of Switzerland is a gem surrounded by green cliffs and snow-capped peaks. Part of the Jungfrau-Aletsch-Bietschhorn UNESCO World Heritage Site, it can be accessed via gondola lift. It's a great attraction for hikers, kayakers, swimmers, and all-around nature-lovers.
