Vibrant River Colors at Caño Cristales, La Macarena

Caño Cristales is a spectacular river found in La Macarena, Meta, Colombia, celebrated worldwide for its dazzling colors. Often called the "River of Five Colors," this unique waterway dazzles with bright shades of red, yellow, green, blue, and black between June and November. The vivid display results from the aquatic plant Macarenia clavigera, which changes color during its life cycle when exposed to sunlight. This phenomenon is extremely rare and occurs almost nowhere else on Earth, making Caño Cristales a standout natural attraction.

The river itself flows over smooth, ancient quartzite rocks estimated to be over a billion years old, creating natural pools, rapids, and waterfalls that enhance the visual appeal. The surrounding Serranía de la Macarena National Park is home to a rich convergence of ecosystems—from the Andes mountains to parts of the Amazon and Orinoco basins—resulting in diverse wildlife including over 420 bird species, reptiles, amphibians, and various fish. The crystal-clear river water, free from sediment and nutrients, allows visitors to see the colorful riverbed in sharp detail.

Historically, Caño Cristales remained unknown to the outside world until discovered by local cattle farmers in 1969. Today, it attracts thousands of visitors annually who seek to witness this colorful spectacle in a protected natural setting. The best period to see Caño Cristales at peak coloration is during the dry season, from late June to early November. This river’s vibrant colors, combined with its geological and ecological richness, make it a truly unforgettable destination for nature lovers.
