Hierve el Agua is a set of natural mineral springs located in the state of Oaxaca, Mexico. The name "Hierve el Agua" means "the water boils" in Spanish, and it is named after the bubbling springs that emerge from the rocks, giving the appearance that the water is boiling.

The water from the springs is rich in calcium carbonate and other minerals, and as it flows down the rock faces, it creates a series of cascading mineral terraces that resemble frozen waterfalls. The terraces are white and turquoise, and the surrounding cliffs are reddish-brown, making for a striking and colorful landscape.

Hierve el Agua is not only a natural wonder but also a popular tourist attraction in the area. Visitors can swim in the cool and refreshing pools created by the springs, hike along the nearby trails to take in the stunning views, or simply relax and soak in the beauty of the surroundings. There are also some small food and souvenir stalls on site.

The area around Hierve el Agua is also known for its rich cultural heritage, with several indigenous communities living nearby, who have their own distinct traditions, cuisine, and handicrafts.
