The Cano Cristales, touted as the most beautiful river in the world (also called as River of five colors), is river flowing in Colombia runs for about 100 km before joining into the main water body. It is located in the northern part of Colombia, in Sierra de la Macarena.

The river can be seen with multi-color mosses and algae all around, at a specified time of a year, otherwise which appear to be dull green and brown all over. The multi-color effect is mainly due to the variation in the water level which is affected during some parts of the year, and thus making the mosses bright up and blooms for the spectators.
