Cano Cristales, also known as the "River of Five Colors," is a Colombian river located in the Serrania de la Macarena province of Meta. It is known for its vibrant colors that come from the aquatic plants and algae that grow on the riverbed, creating a stunning display of red, blue, yellow, green, and black hues. The river is approximately 100 km long and is fed by several small streams and tributaries.

Cano Cristales is a popular tourist attraction and draws visitors from around the world who come to admire its natural beauty. The best time to visit is between June and November, when the water level is low and the colors are at their most vibrant. During the rainy season, from December to May, the river can become muddy and the colors are not as intense.

Due to its remote location and fragile ecosystem, access to Cano Cristales is limited and regulated by the government. Visitors are required to book a tour with a licensed operator and follow strict guidelines to protect the environment.

In addition to the colorful river, the surrounding area is also home to a variety of flora and fauna, including monkeys, toucans, and caimans. The Serrania de la Macarena National Park, where the river is located, is a protected area and has been designated a UNESCO Biosphere Reserve.
