The clear waters of the Verzasca River run for 30km through this rocky valley in southern Switzerland. A dam of the same name, featured in the James Bond movie GoldenEye, blocks the river's flow and forms Lago di Vogorno. Just downstream from it, the river empties into Lake Maggiore (Photo Credit: imgur).
Sabah, Malaysia
Another one from the remote Malaysian state, which covers the northern portion of Borneo and is ringed by reef-rich islands. This photo was taken near Semporna, which is a hub for people who come to dive Malaysian Borneo (Photo Credit: Zahriel).
Pupu Springs, New Zealand
At the very top of the South Island, on Golden Bay, the photographer says: "14000 liters of crystal clear water comes out of these springs per second!" (Photo Credit: pie4dan)
Panari Island, Okinawa, Japan
Panari, also called Aragusuku, is one of the Yaeyama Islands, the most remote area of Japan. The photographer notes: "The islands are also known as one of the world's best diving destinations, having a number of coral species and marine lives as large as those in the Great Barrier Reef. (Over 400 types of corals, 5 types of sea turtles, manta rays, whale sharks and all kinds of tropical fish species all live around Okinawa.)" (Photo Credit: ippei + janine)
Jiuzhaigou Valley, Sichuan, China
In the north of Sichuan province, the Jiuzhaigou Valley is a national park, nature reserve, and UNESCO World Heritage Site. In addition to several crystal-clear lakes, it's a region of multi-tiered waterfalls and snowy mountains. Tourism arrived late but is growing strong, and while swimming isn't allowed...there's always nighttime skinny dipping (Photo Credit: Who is taking pictures?).
Königssee, Germany?
This one's made the rounds on the internet, but no one really seems to know where it was taken, or by whom. The best guess I found was the Königssee, a lake in southern Bavaria, near the border with Austria. If you have any info, clue us in (Photo Credit: Königssee, Germany?).
Bak Bak Beach, Borneo
A shot from the northern tip of Sabah, Malaysia, near Kudat Town. From the photographer: "It takes 3 to 31/2hours drive from Kota Kinabalu city. I wanted to shoot a longer exposure but I had a difficulty judging the light or maybe bcos I was lazy :D kidding. I had to go further the beach, thigh deep and very clear water. Stacked 2 Cokin GND filter P121s, manual exposure 0.25sec, F13." (Photo Credit: Nora Carol).
Lake Marjorie, California
From the photographer: "Lakes in the High Sierra come in a number of colors. Lake Marjorie, at 11,132' has an aquamarine "swimming pool" tint. Crater Mountain dominates the skyline, with Pinchot Pass to the south. I was happy to see clouds at dawn, but by noon a fast moving storm was spitting hail, thunder, and lightning as we cleared Mather Pass. Damn, this spot is gorgeous." (Photo Credit : SteveD).
The Maldives
The 26 atolls that make up the Maldives sit in the Indian Ocean about 400km southwest of the tip of the subcontinent. Abundant reef wildlife (including whale sharks) + incredibly clear waters bring in a lot of tourists. It's also one of Matador's 9 places to experience now before they literally vanish (Photo Credit: >>>"Richy"<< <<).
Rio Sucuri, Brazil
Located in the Pantanal region of Brazil, Rio Sucuri is a spring-fed river that has some of the measurably clearest water on Earth. Multiple tour outfits run trips that let you snorkel the river (Photo Credit: Luiz Felipe Sahd).
Lake Tahoe, Nevada
The photo above was taken in the Bonsai Rock area, on the east shore of the lake, which apparently flies under the radar. Says the photographer: "30 years in Tahoe, and until this winter I'd never heard of it." (Photo Credit: SteveD).
Linapacan Island, Palawan, Philippines

Mystery spot
Another unidentified location. Anyone have an idea? Photo: Imgur
Calanque d'En-Vau, France
Another calanque on the southern coast of France, d'En-Vau has a narrower, steeper channel than Sormiou, giving a real feeling of seclusion and emphasizing the clarity of the water in this cove (Photo Credit: afer92).
Jenny Lake, Wyoming
Jenny Lake sits right below the peak of Grand Teton and is a landmark for many hiking trails, backcountry trails, and climbing routes. Despite the fact that motorboats are allowed on the lake, its waters are still considered "pristine." (Photo Credit: Jeff Clow)
Dog Island, San Blas, Panama
Another from Scott Sporleder, here is a shot from one of Panama's San Blas Islands, the largest of the politically autonomous reservations of the Kuna Indians. (Photo Credit: Scott Sporleder).
Crater Lake, Oregon
Visibility in Crater Lake has been measured at 43.3m -- among the highest in the world. Photographer Rhett Lawrence adds this note about swimming here: "[It's] allowed, but there's only one access point down to the lake -- a steep, mile-long trail (it's easy enough on the way down, but my then-4-year-old daughter did not appreciate the climb back up). Since that's the only access point, you've got to really want to jump in the lake to do it -- especially since it's so damn cold -- but it is permitted by the Park Service."

Cayo Coco, Cuba
A resort island on Cuba's north coast, Cayo Coco is linked to the mainland by a 27km causeway. The adjacent reef and clear waters have earned international recognition as a dive destination (Photo Credit: O.Taillon)
Primosten, Croatia
On the Adriatic Coast north of Split, Primosten is most famous for its vineyards, in addition to beaches that have been voted the best in the country (Photo Credit: Mike Le Gray Photography).
Cala Macarelleta, Menorca, Spain
At the south end of the Mediterranean island of Menorca, the beach at Cala Macarelleta can only be reached on foot or by boat -- probably one of the least-crowded beaches you'll find in Spain (Photo Credit: visualpanic).
Blue Lake, New Zealand
One of many bodies of water in this list that someone or other has claimed has the clearest water in the world, Blue Lake is located in Nelson Lakes National Park, in the Southern Alps of New Zealand.(Photo Credit: Kathrin & Stefan). (By: matador network)
