Rio Celeste, The Blue River

image credit: The.Rohit

Winding through the verdant rainforest of Tenorio Volcano National Park of Costa Rica, is a bright blue river called Rio Celeste. The river is formed by the confluence of two smaller rivers called the Sour Creek and the Good View River. At precisely the point where the waters of the two completely transparent rivers meet, the blue color starts.

It is now known that the blue color arises due to a physical phenomenon known as Mie scattering triggered by the presence of certain minerals in the river's water that causes sunlight to reflect in such a manner that it gives the water its incredible hue.
