5Cano Cristales, Colombia
Cano Cristales, often referred to as the “River of Five Colors” or the “Liquid Rainbow,” is unlike any other river in the world. Located in Colombia’s remote Serrania de la Macarena National Park, Cano Cristales is famous for its vibrant colors, which range from red to yellow, green, blue, and black. This stunning natural phenomenon is caused by a unique aquatic plant called Macarenia clavigera that blooms in the river during the rainy season.
Cano Cristales is not only visually stunning but also represents the incredible biodiversity of Colombia’s tropical ecosystems. The sight of this technicolor river winding through lush green forests and over smooth, polished rocks is truly magical, making it one of the most beautiful rivers on the planet.
