Caño Cristales, Colombia's "River of Five Colours," presents a mesmerizing spectacle of nature's artistry. Between June and November, endemic aquatic plants called Macarenia clavigera bloom, transforming the river with stunning reds and pinks. These colors blend with yellow sand, green algae, blue water, and black volcanic rocks, creating a vibrant palette.

The phenomenon occurs when specific conditions align, requiring clear water, moderate flow, and ideal temperatures. The colors are most vivid from July to September. Reaching this remote location involves a multi-step journey, typically starting in Bogotá, followed by travel to Villavicencio, and then a charter flight to La Macarena. From there, a boat ride and hike lead to the river's entry points.

Visitors must join guided tours, as independent access is prohibited to protect the fragile ecosystem. Accommodation in La Macarena is basic, focusing on eco-tourism. Activities include hiking along the river, swimming in designated pools, and exploring sections like Los Pianos and El Tapete Rojo, adhering to strict environmental rules.
