Description
Titled as Colombia's unique biological wonder, Caño Cristales goes by many identities such as “river of five colors,” “the river that ran away from paradise,” and “the most beautiful river in the world.” Only during the short span between the wet and dry seasons, when the water level is just right, a unique species of plant that lines the river floor called "Macarenia clavigera" turns into a brilliant red During the wet season, the water flows too fast and deep, denying the Macarenia clavigera the sun that it needs to turn red. For a few weeks from September to November, the river transforms into a flowing rainbow. Caño Cristales, is part of National Park Serrania de la Macarena and accessible from the nearby town of La Macarena.
