Seventy-one percent of our planet is covered in water, from oceans to mountain lakes to jungle lagoons. Over time, the names and boundaries of these bodies of water have continuously changed to reflect political, geographical, and historical occurrences. No matter their current names or in whose territory they lie, hundreds of these bodies of water attract visitors year after year due to their crystal-clear nature and vibrant blue appearances — and as long as they’re well cared for, they’ll continue to do so for years on end.

Check out these 20 locations where you can find some of the clearest and bluest waters anywhere on Earth.

Bora Bora, French Polynesia

Home to a multitude of luxury resorts on stilts above the water, Bora Bora attracts tourists from all over the planet looking to get an up-close view of the island’s clear, turquoise waters. The fine white sand surrounding the island accounts heavily for the clarity and color.

Ko Phi Phi, Thailand

The Phi Phi island chain consists of two large islands (Ko Phi Phi Don and Ko Phi Phi Leh) as well as several smaller ones.

Cayos Cochinos, Honduras

One of the most low-key destinations on our list, the Cayos Cochinos are protected by the Honduran government and remain off limits to commercial fishing. The islets are a true example of the word “pristine”—and we all know how overused that is. They're also home to some of the best, and mostly still undiscovered, scuba diving in the world.

Moraine Lake, Canada

Situated in Alberta’s Banff National Park, Moraine Lake is fed by glaciers. The glacial sediment deposited by the runoff gives the lake its blue-green color. Moraine has been used in background images for Windows 7, Bing, Blackberry, Palm, and Android products.

Lake Tahoe, USA

After the Great Lakes, Lake Tahoe is the United States’ largest lake by volume (and the deepest after Oregon’s Crater Lake). While many parts of the lake may not appear to be incredibly clear due to its depth, size, and storm-water runoff, less-impacted spots on Lake Tahoe’s shores show the water’s true colors.

Tulum, Mexico

Peyto Lake, Canada

Peyto Lake is found in Banff National Park. Images of the lake may look computer generated due to the vibrant colors of the water. The large amount of rock flour, deposited from the glacial runoff, give the lake its powder-blue color.

Whitehaven Beach, Australia

The sands of Whitehaven Beach, a 7km stretch of coast in Queensland’s Whitsunday Islands, are composed of 98% silica, which accounts for their fine texture and bright white color. In turn, the clear waters and shallow sands create an impressive swirling pattern when seen from above.

Crater Lake, USA

The main attraction of Oregon’s national park of the same name, Crater Lake has a dark, deep blue color—its water clarity is also remarkable. The lake sits in a caldera, which was created after the collapse of the Mount Mazama volcano over 7,000 years ago.
