What is Hierve el Agua?
Hierve el Agua, translating to “the water boils,” is a set of natural rock formations that resemble cascading waterfalls. These formations are created by freshwater springs saturated with calcium carbonate and other minerals. As the water flows over the cliffs, it deposits minerals, forming stalactite-like structures over thousands of years.
The site features two main formations: Cascada Grande and Cascada Chica. Cascada Grande is the larger of the two, extending down from a base approximately 90 meters wide and 80 meters above the valley floor. Cascada Chica, also known as the Amphitheatre, contains two large artificial pools for swimming and several small natural pools.
