Rainbow River is situated in____________?

  • Columbia
  • Japan
  • Pakistan
  • New Zealand
Correct Answer: A. Columbia

Detailed Explanation

The correct answer is Colombia (often misspelled as Columbia in MCQs).The Caño Cristales river, located in the Serranía de la Macarena province of Colombia, is widely known as the "Liquid Rainbow" or the "River of Five Colors." It is frequently cited as one of the most beautiful rivers in the world.


Why is it called the Rainbow River?


The river appears to change color due to a unique biological phenomenon. Between the wet and dry seasons (usually from July to November), the riverbed displays vibrant shades of red, yellow, green, blue, and black.



  • The Macarenia clavigera: The bright red and pink colors are caused by a specific endemic aquatic plant called Macarenia clavigera that clings to the rocks in the riverbed.

  • Environmental Factors: The color intensity depends on the amount of sunlight and the water level, which provides the plant with the necessary nutrients and light to "bloom" in these brilliant hues.


Geography and Access:


The river is located in a remote, protected national park. Because the ecosystem is extremely fragile, the Colombian government strictly regulates the number of visitors and prohibits the use of sunscreen or insect repellent while swimming to protect the delicate plants.


Comparison of the Options:



  • Colombia: The correct answer. (Note: "Columbia" with a 'u' usually refers to the District of Columbia in the USA or the university, whereas the country is spelled "Colombia").

  • Japan: Known for its blue ponds (Hokkaido) and cherry blossoms, but not the Rainbow River.

  • Pakistan: Home to the Indus and Jhelum rivers, famous for their historical significance but not for this specific multicolored phenomenon.

  • New Zealand: Famous for its "Waikato River" and "Blue Springs," but lacks the Macarenia clavigera plant required for the "rainbow" effect.
