Hot Springs of Yellowstone National Park (USA)
Yellowstone National Park in Wyoming is the most active geothermal region on the planet. It is home to the largest hot spring in the United States, which was named Prismatic due to its rainbow-colored waters. The brightness of the spring is provided by pigmented bacteria. The shores of the reservoir are orange, and further away, the waters are blue-green-yellow. The temperature near the shore is about 50 degrees, closer to the center 70, and at depth and in the interior over 800 degrees. Tourists come just to admire it.
Lake Tuz Golu (Turkey)
Salt Lake Tuz Golu is the second largest lake in Turkey. It is both an industrial center (factories extract salt here) and a popular tourist destination. Travelers enjoy walking on the lake when the water evaporates due to summer heat and the landscape takes on a whimsical appearance. But before the sun dries up Tuz Golu, it turns a bright red color due to active algae blooms. What a paradise for photographers! However, drinking the water is not recommended, despite the antioxidant properties of red algae. The lake is protected by UNESCO because it is home to flamingos that are endangered in Europe.
Lakes of Mount Kelimutu (Indonesia)
Kelimutu is a volcano on the Indonesian island of Flores. Due to its three crater lakes, each colored differently, Kelimutu is a popular tourist attraction. The three lakes, which contain dissolved minerals, change their color over several years from black to turquoise, reddish-brown, or green. The lake on the western side of the volcano is called Tiwu Ata Mbupu ("Lake of Old People"), the other two are called Tiwu Nuwa Muri Kooh Tai ("Lake of Young Men and Maidens") and Tiwu Ata Polo ("Enchanted Lake"). Local residents from the village of Moni, located at the foot of the volcano, believe that the souls of the dead go to these lakes and that changes in their color mean they are angry.
Caño Cristales (Colombia)
Caño Cristales in the Macarena National Park in Colombia is called the most beautiful river in the world. Its waters are five-colored, with shades of yellow, blue, green, black, and red. Caño Cristales becomes this bright in summer when numerous algae bloom. There are no fish in the river, but people can take a dip; the water is very clean and clear.
Hot Springs in Dallol (Ethiopia)
The hot springs in Dallol (Ethiopia) attract a large number of tourists due to their almost fluorescent brightness. The landscapes here are simply alien.
Lake Spencer (Australia)
Pink Lake, or Lake Spencer, is located in the city of Esperance (Western Australia). Its color is due to the presence of algae unaliella salina (the algae are green but produce the colored pigment carotene to protect themselves from sunlight). A few years ago, Pink Lake suddenly began to pale, much to the dismay of locals and tourists. But in the last year or two, the water has regained its former bright color.
Five Flower Lake (China)
Five Flower Lake in Jiuzhaigou (China) makes one wonder: isn't this computer graphics? Its color can change and be yellow, green, or bright turquoise. The depth is great (up to 40 meters), but the water is always very clear, revealing ancient trees resting on the bottom. It is thought that the wood, reacting chemically with various minerals in the water, gives the reservoir its unusual color, but the secrets of the lake are not known for certain. Local residents are somewhat afraid of it, considering it mystical.
Spotted Lake (Canada)
Kliluk, or Spotted Lake, is located in Canada, near the town of Osoyoos, not far from the US border. The lake's water is saturated with various minerals and has the world's highest concentration of magnesium sulfate (Epsom salt), calcium, and sodium, as well as silver and titanium. In hot summer weather, as the water evaporates, many spots of bizarre shapes form on the lake's surface, which can take on different shades depending on weather conditions. At the same time, islands of minerals are exposed, covered with a hard crust that can be walked on. The waters of the lake have a therapeutic effect.
Lake in Beppu (Japan)
In the Japanese city of Beppu, there are many lakes and geysers; it is a well-known hot spring resort in the country. But one body of water stands out for its "hellish" character: red color, clouds of steam above the surface, high (90 degrees) water temperature - evidence of the proximity of a geyser and the magma beneath it. The lake both attracts and frightens: it is a tourist attraction, but certainly not a place for swimming, so the reservoir is fenced off.
Blue Lake (Australia)
Blue Lake in Mount Gambier (South Australia) is of volcanic origin. Its average depth is 72 meters. But it is famous, of course, not for its depth, but for its color. Blue Lake supplies the city of Mount Gambier with drinking water.
Rio Tinto River (Spain)
Rio Tinto is a river in southwestern Spain in the region of Andalusia. For three thousand years, mining has been carried out in its upper reaches, leading to high concentrations of copper and iron in the water. The high acidity of the waters makes the river unsuitable for swimming and even dangerous for people, but Rio Tinto is of great interest to scientists and photographers.
Great Blue Hole (Belize)
The Great Blue Hole (that's what the place is called) appears as a circular black hole among the turquoise waters near Belize. Its unexpectedly gloomy color for the tropics is due to a sharp change in depth. This place is a diver's dream, and snorkeling enthusiasts come from all over the world, getting there from the capital of Belize by boat or motor launch. They want to see with their own eyes underwater caves, stalactites and stalagmites, and amazing creatures that live only at great depths.
