Hierve el Agua is one of Mexico’s most beautiful natural sites and a sacred place for the indigenous Zapotec people. These petrified waterfalls seem frozen in time — and they practically are, as they’ve been in the making for thousands of years. As water from natural springs flows over the side of the cliffs, the minerals from the water create rock formations, much in the same way that stalactites form in caves. Bring your swimsuit, as you can bathe in the natural and manmade pools at the top!
In addition to admiring the calcified cliffs, there are also hikes in the area, which is a good way to get away from the crowds.
Open daily 7am-6:30pm. Admission is 50 MXN.
