Hierve el Agua

Hierve el Agua (Spanish for "the water boils") is a set of natural travertine rock formations in San Lorenzo Albarradas, Oaxaca, Mexico that resemble cascades of water. The site is located about 70 km east of Oaxaca City, and consists of two rock shelves or cliffs which rise between fifty and ninety metres from the valley below, from which extend nearly white rock formations which look like waterfalls. These formations are created by fresh water springs, whose water is over-saturated with calcium carbonate and other minerals.
