Caño Cristales (Caño Cristales - Crystal River), or river of five colors, as it is known locally,
originates in the south of the mountain chain Macarena, Colombia, and flows to the east, to the confluence of the river Guayabero.
In the box Caño Cristales there are five colors: yellow, blue, green, black and red.
All of them are the product of life and numerous algae,
depending on the time of year, their saturation or weakened or strengthened.
The water in it is so clean that the bottom can be seen even at a decent depth, but there are no fish due to the unique characteristics of the channel.
The summer sun dries the plant called Macarenia Clavijera, and the river becomes a rich red color.
