Caño Cristales, The River Of Five Colors, Serrania De La Macarena, Meta, Colombia

Description
A unique biological wonder, Caño Cristales has been referred to as "the river of five colors", "the river that ran away from paradise", and "the world's most beautiful river".
For most of the year, Caño Cristales is indistinguishable from any other river: a bed of rocks covered in dull green mosses are visible below a cool, clear current.
