What’s at the end of a rainbow? Perhaps it’s not actually a pot of gold, but a fantastic and colorful river.

Caño Cristales in Colombia’s Serranìa de la Macarena National Park is dubbed the “river of five colors,” “liquid rainbow,” or “melted rainbow” because of the many hues you can see beneath its clear waters. In certain light and water conditions, bright greens, yellows, reds, and purples may appear to flow down the river. Sometimes, the river can also appear a bright blue, hot pink, orange, or a deep maroon.
