The Most Bizarre Lakes in the World: Nature’s Strangest Waters
From blood-red waters to vanishing acts, discover the world’s strangest and most spectacular lakes, each with a unique story to tell.
The Most Bizarre Lakes in the World
Our planet is home to millions of lakes, but only a rare few break the norms of ordinary freshwater or saltwater pools. Across continents, some lakes bubble at boiling temperatures, some turn bubblegum pink or blood red, while others brim with millions of harmless jellyfish or even vanish before your eyes. From chemical extremes to mind-bending ecosystems, here is a comprehensive tour of Earth’s most bizarre lakes and the strange phenomena that make them unique.
Spotted Lake, Canada
Spotted Lake, or Kliluk, lies in British Columbia’s Okanagan Valley and grabs attention every summer as water evaporates, revealing hundreds of colorful mineral-rich spots. Each spot contains a different concentration of minerals, giving the lake its polka-dotted pattern with hues of yellow, green, and blue. Historically sacred to indigenous people, Spotted Lake’s surreal appearance continues to fascinate and surprise visitors and scientists alike.
- Contains dense deposits of magnesium sulfate, calcium, and sodium salts.
- Patterns and colors change based on rainfall and mineral composition.
- Considered sacred by the Syilx (Okanagan) people.
Pitch Lake, Trinidad
Pitch Lake in La Brea, Trinidad is the world’s largest natural deposit of asphalt (bitumen); a thick black mixture of hydrocarbons usually found on roads, not in lakes. Discovered in 1595 by Sir Walter Raleigh, Pitch Lake covers around 0.4 square kilometers and is thought to be about 75 meters deep. Despite its sticky terrain, Pitch Lake brims with life: unique microbial communities survive by feasting on the hydrocarbons, making it Earth’s closest analog to the methane lakes on Saturn’s moon Titan.
- Estimated to hold 10 million tons of natural bitumen.
- Site of unique extremophile microbes.
- Historical use: Sir Walter Raleigh waterproofed his ships with the pitch.
Lac Rose (Lake Retba), Senegal
Lac Rose, just north of Dakar, Senegal, occasionally glows bubble-gum pink—a hue caused by the presence of Dunaliella salina algae. This microorganism produces red pigments in response to the lake’s high salt content. During the dry season, evaporation amplifies both the color and salt level, making the water denser than the Dead Sea.
- Salt concentration reaches 40%, much higher than sea water.
- Pigments shield algae from intense sunlight.
- Salt harvesting supports local economies.
Lake Natron, Tanzania
Lake Natron in northern Tanzania is a soda lake famed (and feared) for its deadly, blood-red waters. The high alkalinity (pH up to 10.5) and temperatures up to 60˚C create a caustic environment where almost nothing survives—except salt-loving cyanobacteria that give the lake its color. Intriguingly, any animals that die in the lake are calcified, appearing to turn to “stone.” Despite, or perhaps because of, these extremes, Natron serves as a crucial breeding ground for millions of lesser flamingos, which thrive on the nourishing algae.
- Caustic water due to sodium carbonate and baking soda.
- Famed for dramatic photographs of calcified birds and animals.
- Key ecosystem for flamingo populations.
Jellyfish Lake, Palau
Jellyfish Lake on Eil Malk Island in Palau contains millions of golden jellyfish (Mastigias papua etpisoni) that migrate daily, following the sun. Isolated from the ocean for thousands of years, the jellyfish here lost their stingers due to the absence of natural predators, making it possible—and safe—for tourists to swim among them.
- One of about 70 marine lakes in Palau, but the only one open to tourists.
- Extraordinary daily vertical migration by jellyfish.
- Snorkeling here offers an ethereal underwater experience.
Boiling Lake, Dominica
Boiling Lake in Morne Trois Pitons National Park, Dominica, is the world’s second-largest hot lake. This 200-foot-wide lake is actually a flooded volcanic fumarole, with constant bubbling and temperatures reaching 82–91°C near the edges, making swimming impossible. Its position atop active geothermal vents makes Boiling Lake hazardous but spectacular.
What others are reading
- Fed by rainfall and two small streams.
- Center is often obscured by vapor clouds due to high heat.
- Access requires a challenging, steep hike through rainforest.
Lake Baikal, Russia
Lake Baikal in Siberia holds multiple records: the world’s deepest lake (more than 1,600 meters), the largest by volume, and the oldest (about 25 million years). Its endemic species include the only freshwater seal, the Baikal seal or nerpa. During winter, Baikal’s surface freezes thick, but its deep waters stay liquid—aided by geothermal heat—and the ice develops intricate fractures and bubbles, captivating photographers and researchers alike.
- Contains nearly 20% of the world’s surface fresh water.
- Over 1,700 endemic plants and animals, including omul fish.
- Crystal-clear ice with frozen methane and unique blue cracks in winter.
Lake Hillier, Australia
Lake Hillier on Middle Island, Australia, is celebrated for its striking, permanent pink color. The distinct hue is due to the interaction of Dunaliella salina algae, halophilic bacteria, and high salt concentrations, but the precise mechanism remains a topic of research. Surrounded by eucalyptus trees and white beaches, Lake Hillier remains a protected site, only visible from the air or by boat.
- Color persists year-round, even when water is collected in containers.
- No adverse effects for human swimmers—though trips are restricted.
Vanishing Lake (Loughareema), Northern Ireland
Loughareema, better known as the “Vanishing Lake” of County Antrim, amazes visitors with its disappearing act. Fed by streams but drained by subterranean sinkholes, the lake can fill or empty entirely within hours or days, depending on rainfall and how clogged the drains are with debris or peat. The phenomenon has fueled local legends—and confounded road-builders.
- Fills quickly after heavy rain, then vanishes mysteriously.
- Unique karst geology makes rapid drainage possible.
- Sometimes dry, sometimes full: an unpredictable landscape.
Mystery of Melissani Cave Lake, Greece
Melissani Cave Lake on the island of Kefalonia was hidden for centuries and only revealed to the world after an earthquake in 1953 collapsed its roof. Today, sunlight entering the cave gives the waters a mesmerizing blue glow. Ancient Greeks believed the cave to be the home of nymphs and associated it with the mythical tales of Homer.
- Cave lake is 20–30 meters deep; sunlight causes lit-up blue waters.
- Near the ancient city of Sami, with archaeological significance.
- Open for guided boat tours through the cave system.
Wuhua Hai (Five Flower Lake), China
Wuhua Hai (Five Flower Lake) in Jiuzhaigou, Sichuan, is known for its uniquely clear turquoise, green, and yellow tones that change depending on light, season, and algal growth. Submerged ancient tree trunks are visible on the lakebed, while surrounding forests and snow-dusted mountains make this UNESCO World Heritage site truly enchanting.
- Shallow lake, rarely more than 5 meters deep.
- Mineral-rich, with high calcium carbonate content.
- Renowned for clarity; sunken trees visible beneath the surface.
Lake Nyos, Cameroon
Lake Nyos in Cameroon appears ordinary but hides a deadly secret—the ability to unleash lethal clouds of carbon dioxide. In 1986, a limnic eruption released a massive CO2 cloud from deep within the lake, resulting in almost 1,800 deaths from asphyxiation. Measures have since been put in place to vent gas safely, but Nyos remains one of the world’s most dangerous lakes.
- Located atop a volcanic crater with high levels of dissolved CO2.
- The 1986 disaster remains unmatched in modern times.
- Artificial degassing systems now operate continuously.
Kelimutu Lakes, Indonesia
Kelimutu is a group of three volcanic crater lakes on Flores Island, remarkable for their ever-changing colors—from turquoise to red to brown. The colors shift due to varying mineral oxidations, volcanic activity, and micro-organism populations. Revered by locals, the lakes are said to hold the souls of the deceased, with each lake reserved for a different group: young people, old people, and evil people.
- Lakes share a volcano but never directly mix water.
- Color changes driven by chemical composition and oxidation state.
- Significant cultural and spiritual importance.
Plitvice Lakes, Croatia
Plitvice Lakes National Park comprises a cascading series of 16 terraced lakes interconnected by waterfalls and streams. What makes them unique is the constant deposition of tufa (a type of limestone), driven by moss, algae, and bacteria that trap and crystallize calcium carbonate, constantly reshaping the lakes’ boundaries and waterfalls.
- UNESCO World Heritage Site and major tourist attraction.
- Water clarity and intense aquamarine colors result from limestone bedrock.
- Frequent changes as water flows and mineral deposits build up over time.
Mono Lake, USA
Mono Lake in California stands out for its eerie landscape of tufa towers—spiky calcium-carbonate formations rising from the lakebed. The highly saline and alkaline waters support vast colonies of brine shrimp and alkali flies, which provide food for millions of migrating and nesting birds.
- Tufa towers form underwater, exposed by falling water levels.
- No fish survive, but huge populations of brine shrimp thrive.
- Important stop on the Pacific Flyway for migratory birds.
Gaet’ale Pond, Ethiopia
Gaet’ale Pond in the Danakil Depression is often cited as the saltiest body of water on Earth, more saline than even the Dead Sea. Formed by seismic activity, the water is nearly saturated with salt, and ponds bubble with dangerous gases such as carbon dioxide and sulfur dioxide, making human contact hazardous.
- Salinity sometimes exceeds 43%.
- Vibrant colors due to algae and chemical deposits.
- Extreme heat, chemical hazards, and no signs of macroscopic life.
Mega Lake Paratethys (Prehistoric, Europe & Asia)
Lake Paratethys isn’t visible today, but 6 million years ago it was the largest lake ever known—stretching across central Europe and western Asia. At its peak, it covered 2.8 million square kilometers and supported unique animal species, including some of the smallest whales that ever lived. Paratethys dried out due to climate changes and land uplift, leaving extraordinary fossils as evidence.
- Formed by isolation of Paratethys Sea circa 12 million years ago.
- Contained more water than all present freshwater lakes combined.
- Home to mini whales like Cetotherium riabinini.
Frequently Asked Questions (FAQs)
Q: Why do some lakes change color over time?
A: Lakes can change color due to shifts in algae or bacterial populations, varying mineral content, temperature, or even volcanic and chemical activity that affect water chemistry.
Q: Can you swim in these bizarre lakes?
A: Swimming is allowed in some, such as Lake Hillier and Jellyfish Lake, under regulated conditions. However, lakes like Boiling Lake, Gaet’ale Pond, and Lake Natron are unsafe due to extreme temperatures, salinity, or hazardous chemicals.
Q: What are tufa towers and how do they form?
A: Tufa towers are spires of calcium carbonate that form underwater in alkaline lakes (like Mono Lake) when calcium-rich spring water meets carbonate-rich lake water, causing minerals to precipitate out and stack up in intricate structures.
Q: Are there any lakes that disappeared or changed drastically in recorded history?
A: Yes. The Aral Sea, between Kazakhstan and Uzbekistan, has been extensively documented as a “disappearing” lake, shrinking by over 90% due to water diversion projects.
Q: What’s the most dangerous lake on Earth?
A: While several lakes present dangers—either through toxicity, like Lake Natron and Gaet’ale Pond, or sudden limnic eruptions, like Lake Nyos—the title may belong to Lake Nyos due to its lethal history involving CO2 releases.
