River of Five Colours – Caño Cristales

Princy P. John 0

Caño Cristales, also known as the river of five colours is one of the most spectacular natural wonders of the world. The natural beauty is found in the mountain range of Serranía de la Macarena, Colombia.

The river exhibits mesmerising colours of vivacious yellow, green, blue, black and red shades.

The liquid rainbow is caused by a unique phenomenon: a unique species of red plant – Macarenia clavigera – growing in the riverbed turning sparkling red. Other colours come from black rocks, green algae, blue water and yellow sand, producing an iridescent effect.

This special effect in the water occurs for a brief period of time every year when the atmospheric and climatic conditions are just apt. From the month of July to November, the river becomes colorful.
