This River in Colombia Is a Liquid Rainbow You Have to See to Believe

Hidden deep within the heart of Colombia lies a natural wonder so stunning it seems almost unreal: Caño Cristales, often called the “River of Five Colors” or the "Liquid Rainbow.” Unlike any other river you've likely encountered, Caño Cristales explodes with vibrant hues, transforming its crystalline waters into a kaleidoscope of red, yellow, green, blue, and black. This isn't the result of pollution or artificial dyes; it's a completely natural phenomenon.

The Science Behind the Spectacle: Macarenia Clavigera

The key to Caño Cristales' mesmerizing colors lies in a unique aquatic plant called Macarenia clavigera. This plant clings to the riverbed and, under specific conditions, undergoes a transformation that gives the river its famed chromatic display. The intensity and range of colors are dependent on factors like water level, sunlight, and temperature.

When the water level is low and the sun shines brightly, Macarenia clavigera thrives. It's during this period, typically between July and November, that the river truly comes alive with its breathtaking colors. The red hues, the most prominent, are directly attributed to the Macarenia clavigera. Other colors, such as yellow and green, are derived from other algae, sand, and the varying depths of the water.
