Caño Cristales’ beauty has inspired many nicknames: “The River That Escaped Heaven,” “The Liquid Rainbow” and “The River of Five Colors.” From late May to early November, a special algae blooms on the bottom of the river, giving it hues of green, blue, black, yellow and red.
The result is an otherworldly experience that you’ll be hard-pressed to find in any other country. To protect this unique landscape, you can only visit with a certified tour group and must wear natural sunscreen.
