Located on the Yucatán Peninsula in southeastern Mexico, Cenote Ik Kil is originally known as a cavernous sinkhole for Mayan human sacrifice to a rain god. But don’t worry; there won’t be any sacrifices – just pure bliss!

The 360-foot all-natural pit – formed by a cave collapse – is a popular stopover for those traveling to the ancient Mayan city of Chichen Itza. You reach the water by walking down a stairway carved into limestone.

It can get a bit crowded, so make it an early stop for the most serene dip. After your swim you can fill up on a traditional Mexican lunch buffet at the restaurant on site.

Blue Lagoon, Grindavik, Iceland

The Blue Lagoon in Iceland

Already one of the best tourist attractions in the world, the Blue Lagoon and its steamy waters makes for an energizing and scenic swim.

Located in Grindavik, just a 50-minute drive from Reykjavik, the man-made Lagoon was created in the late 1970s, and contains 1.5 million gallons of geothermal seawater from deep inside the Earth. At a temperature of 100°F, you are guaranteed a relaxing – and toasty – swim all year round.

The waters are thought to have a “healing quality” and are full of minerals like silica and sulfur. There are luxurious offerings here: put some silica mud on your face for softer skin, pay a visit to a waterfall that can heal shoulder pains or get an in-water massage. Relaxation is the key word at the Blue Lagoon!

If you think Texas is just cowboy hats and boots, you’re sorely mistaken. It’s also home to one of the most beautiful natural swimming pools in the States, the Hamilton Pool.

The pool is very popular during the hot Texan summers, with waits of up to 1 hour. In order to access it, you’ll need to take a half-mile steep hike. But once you’re in, you are guaranteed one of the most splendid swims in Texas. If you didn’t bring a picnic basket, you can always grab a bite at the nearby It’s All Good BBQ restaurant.

It might be hard to leave Jamaica’s sandy beaches behind in order to drive inland, but once you jump into this natural swimming pool, you’ll never want to leave. The road to the Blue Hole is quite rough, so make sure you have a sturdy car. You can pair a visit to the hole with a quick stopover to Dunn’s River Falls.

For the adventurous: Take the plunge from the Tarzan Rope swing overhead into the more-than-30-foot-deep hole. For the cautious: Floating in the waters while inching your way in is OK, too.

Little River Canyon, Alabama, United States

The name might be misleading – Little River Canyon isn’t little at all. This stunning sinkhole is 12 miles long, and surrounded by cliffs and gigantic sandstone jump-off points jutting from the waters.

Considered one of the cleanest and wildest waterways in the South, the river runs along the top of Lookout Mountain from northwestern Georgia to the river’s end in Fort Payne, Alabama. Leap into the pristine waters from one of three rope swings outside the hole and get that unique feeling of freshness one can only get in natural waters.

Whether or not anything magical happens when you enter the clear blue lakes and waterfalls of the Fairy Pools on the Isle of Skye is unknown, but a visit to the blue- and pink-hued waters conjures up mental images of a fairy tale land.

Located at the foot of the Black Cuillins near Glenbrittle, the mystical waters of the Fairy Pools are great for swimming. Though the waters may look warm, they are rather on the frigid side of the thermometer. You are after all in northern Scotland!

After a refreshing swim, you might be ready for a warm beverage. A visit to the Wee Tea Room, a small personally run café located in the middle of the moorlands by Eynort, might be just the answer.

Cummins Falls State Park, Tennessee, United States

Jade green waters and serene surroundings at Cummins Falls in Tennessee, US

Situated halfway between Nashville and Knoxville, this swimming pool is definitely a hidden gem. This area was a popular hunting ground for Native Americans as large populations of buffalo used to roam around, so it’s not so out of the ordinary to find arrowheads along the river.

Cummins Falls is not for amateurs. You will have to hike, wade and climb to get to the rope that walks you down to the water’s edge. Though the hike is only 2.5 miles, the level of activity makes it one for adventure seekers. Remember to pack your hiking shoes along with a swimming suit and flip-flops and be mindful of the weather as sudden rainfalls can cause flash floods.

Cool off by jumping in the forest green water and taking a swim beneath the spectacular waterfall.

Devil’s Pool sits atop the famous and breath-taking Victoria Falls. The natural swimming pool gives way to a whopping 360-foot drop off. It’s only “open” during the drier months of the year – May through October – when the water levels of Victoria Falls are low enough for the pool to appear.

From farther away, travelers can see the “Smoke that Thunders,” the name given to the fall’s cascading waters, which are the largest in the world. But not to worry, guides are on hand to ensure your safety and you’re encouraged to bring a (waterproof!) camera to document the plunge.
