Located in Colombia, Caño Cristales displays a variety of mosses, aquatic plants, and the region’s unique red algae “Macarenia Clavigera.” As the rainy season ends and the river’s water level drops, these colors emerge alternately from the riverbed, creating a stunning rainbow-like landscape. This is why Caño Cristales is also known as the Five-Color River or Rainbow River, and is hailed as the most beautiful river in the world.

Caño Cristales, located within Colombia's Macarena Mountains National Park, attracts numerous tourists and photographers every year. The river displays five colors created by a mix of yellow sand, rocks, aquatic plants, and reflections of trees and the sky. Rapids and waterfalls have also carved out various small and large pits in the riverbed, forming a uniquely beautiful landscape.
