Before we get into trip logistics, let’s unpack the science behind these incredible petrified ‘waterfalls’ and clear up some naming confusion.

Why is it called Hierve el Agua Mexico?

The name “Hierve el Agua” literally translates to “the water boils” in Spanish. But here’s the kicker – the water isn’t actually boiling hot at all! It’s a bit of a misnomer. So what’s with the deceptive moniker?

Turns out, the site was named ages ago by the indigenous Zapotec people who have inhabited this valley for millennia. They observed how the spring water percolated and bubbled up from the ground in certain spots, giving it a carbonated or ‘boiling’ appearance. But in terms of temperature, the water is actually quite mild, hovering between 72-81°F (22-27°C). So don’t show up expecting a hot tub.

The key thing ‘boiling’ here is really the earth’s crust. This area is geothermally active, with underground volcanic processes that infuse the springs with dissolved minerals and gas. As the mineralized water trickles out of cracks in the rock, it reacts with the air and calcifies over time, building up into the surreal rock formations we see today.

The best way to go to Hierve El Aqua Oaxaca is by going on a private tour or small guided tour. Here are 3 tours that I hand picked with the best reviews and best overall value.

How the hierve de agua petrified falls formed

The iconic petrified ‘waterfalls’ of Hierve el Agua are the result of a fascinating geological process playing out over hundreds of thousands of years. Here’s how it works:

1. Rainwater absorbs CO2 as it percolates down through the soil and limestone bedrock
2. Underground, the CO2-enriched water becomes acidic and dissolves minerals like calcium carbonate
3. This mineral-saturated water gets heated by geothermal activity and starts rising back up through cracks
4. As the hot mineral water emerges and makes contact with air, dissolved minerals precipitate out
5. Drip by drip, precipitated minerals accumulate into porous rock called travertine, forming terraces
6. Over millennia, layers of travertine build up into the petrified waterfall-like structures we see today

The same process also formed the dazzling mineral pools at the top of the falls. There, the spring water is saturated with calcium, magnesium, sulfur and iron, giving it a striking yellow-green hue.

• Just 2 petrified waterfalls like this exist in the world – the other is Pamukkale in Turkey
• Hierve el Agua’s falls are relatively ‘young’ in geological terms at ~50,000-250,000 years old
• The large falls (Cascada Grande) measures ~100 ft tall; the smaller one (Cascada Chica) drops ~40 ft
• Mineral content of spring water: calcium carbonate, magnesium, sulfur, iron
• Bedrock composition: Cretaceous-era limestone/dolomite

Cultural Significance of hierve el agua

Zapotec Heritage For the indigenous Zapotec people who have called this valley home for thousands of years, Hierve el Agua holds deep cultural and spiritual significance.

Archeological evidence suggests the Zapotecs built canals to harness the spring water for irrigation and drinking water as far back as 2,500 years ago. The site may have also served ceremonial purposes. The springs were likely revered as a sacred life-giving resource in the semi-arid landscape.

Fast forward to today, and Hierve el Agua still plays a vital role for the local Zapotec communities of San Lorenzo Albarradas, San Isidro Roaguía, and others. Income generated from tourism has become an economic lifeline, as more visitors flock to marvel at the geological wonders in their backyard. Yet with the benefits of tourism also come challenges – more on that later.

As you explore the site, take a moment to appreciate the generations of Zapotec people who have been stewards of this land and consider how your visit can support their well-being.
