For most part of the year, the Caño Cristales river in Colombia is just like any other river in the world. But when the season is just right, it transforms into the most beautiful river in the world:
During Colombia's wet season, the water flows fast and deep, obscuring the bottom of the river and denying the mosses and algae that call the river home the sun that they need. And during the dry season there is not enough water to support the dazzling array of life in the river. But during a brief span between the wet and dry seasons, when the water level is just right, the many varieties of algae and moss bloom in a dazzling display of colors. Blotches of amarillo, blue, green, black, and red--and a thousand shades in between--coat the river.
