HIERVE EL AGUA WATERFALLS
Hierve el Agua is a must see if you are visiting Oaxaca, this stunning rock formation that has the appearance of a waterfall is the result of thousands of years of Calcium Carbonate deposits from two independent springs.
The calcified water of Hierve el Agua ‘boils’ to the surface due to hydraulic pressure within the rocks, and nowadays is now channelled into two man-made pools where it is possible to swim.
Hierve el Agua is not just a picturesque natural spring however; it is also of cultural importance as it is thought to have been a scared site for the ancient Zapotecs who probably marvelled at this water bubbling out of the ground in what is essentially a very arid area. Hierve el Agua is also home to an ancient irrigation system dating back 2500 years and the only one of its kind in Mexico.
