From bubblegum pink to rainbow waters: 5 stunningly unusual coloured rivers and lakes around the world

Nature is full of surprises, and some of the most stunning wonders can be found in the form of rivers and lakes with unusual colours. From bright pink waters to deep red hues, these striking bodies of water look almost unreal. Here are five of the most fascinating coloured rivers and lakes from around the world.

Often called the "Liquid Rainbow," Caño Cristales in Colombia is one of the most stunning rivers in the world. During certain months of the year, the river turns into a breathtaking mix of red, yellow, green, blue, and black. This unique colour display is caused by the aquatic plant Macarenia clavigera, which changes colour under the right conditions.

Lake Hillier in Australia is famous for its striking pink colour, making it look like something out of a fairytale. The exact cause of its pink hue is still debated, but scientists believe it comes from a combination of salt-loving bacteria and algae that produce a reddish pigment. Unlike other pink lakes, Lake Hillier’s colour remains vibrant all year round, and even when the water is collected in a bottle, it stays pink!

The Rio Tinto in Spain gets its deep red colour from the high concentration of iron and other minerals in the water. This river has been heavily mined for centuries, which has contributed to its acidic nature. Despite its seemingly hostile environment, some microorganisms have adapted to survive in the river, making it an interesting location for scientists studying extreme life forms.

Lake Natron in Tanzania is known for its eerie red colour and extreme conditions. The lake is highly alkaline due to high amounts of sodium carbonate, making it uninhabitable for most wildlife. However, certain algae and microorganisms thrive here, giving the lake its deep red and orange hues. The lake is also known for its ability to preserve dead animals, turning them into stone-like figures due to its unique chemical composition.

Laguna Verde in Bolivia is a spectacular saltwater lake that glows a stunning emerald green. The lake’s unique colour is due to its high content of minerals like copper and arsenic. Situated at the foot of the Licancabur volcano, the lake changes shades depending on the sunlight and wind, creating a mesmerising sight for visitors. Although it looks inviting, the water is highly toxic, making it unsuitable for swimming or drinking.
