This is the Caño Cristales. For a brief period each year, this unique Colombian river blooms in a dazzling multi-colored display.

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.
