Also known as the River of Five Colors, Caño Cristales is the most spectacular natural wonder in the country. Found in the mountain range of Serranía de la Macarena, the river mesmerizes with amazing colors: vivacious yellow, green, blue, black and red shades quiver from the bottom.

          The Liquid Rainbow is caused by unique phenomena: a red plant – Macarenia clavigera – growing in the riverbed. Other colors come from black rocks, green algae, blue water and yellow sand, producing an iridescent effect. The river also features waterfalls, pools and caverbs, making it even more dramatic. Furthermore – there are no fish or other creatures,so visittors can enjoy uninterrupted bathing in Caño Cristales.
