Hierve el Agua means “the water boils”, though the water is cool. Mineral-rich springs spill over a cliff edge in the Sierra Madre del Sur and, over thousands of years, have deposited calcium carbonate that hardens into frozen-looking cascades. There are two main formations, and a set of natural pools at the top with views across the valley. It is one of the most photographed spots in Oaxaca state and an easy full-day excursion from the city. For other nearby options, see our Oaxaca City day trips guide.
What you will see
The two petrified cascades are the main attraction. The larger one, the Cascada Grande, is a white limestone formation that falls roughly 30 m down the cliff, and a hiking trail leads around the base for a view back up. At the top, the natural pools sit right on the cliff edge and make a good place for a swim with mountain views behind.
There is also a short upper trail with viewpoints. Allow 2 to 3 hours on site, including the walk down and the climb back.

How to get there
By tour (easiest). Most operators run a full-day trip that combines Hierve el Agua with Mitla ruins, a mezcal distillery stop and sometimes Teotitlán del Valle and the Tule tree. Pickup is from central Oaxaca around 9:00. Browse Hierve el Agua tours on GetYourGuide to compare group sizes and inclusions.
By colectivo (cheapest). Take a colectivo or bus from Oaxaca to Mitla (about 1 hour, roughly MXN 40), then a shared pickup truck from Mitla to the site (about 45 minutes). Returns run until mid-afternoon, so plan to leave before 15:30 and confirm the last departure when you arrive.
By car. Take Highway 190 east toward Mitla, then follow signs for Hierve el Agua. The last 20 km are steep and winding. Hire cars in Oaxaca typically cost from around USD 35-50 per day, and parking is at the entrance.
When to go
Arrive early, ideally before 10:00. The pools are less crowded, the light is better and the air is cooler. The dry season from November to April offers clearer views. During the rainy season (June to October), the cascade can look more vivid, and trails may be slippery, with an increased chance of closure.
The site is busiest on weekends and holidays. Midweek is noticeably quieter.
What to bring
- Swimsuit and quick-dry towel
- Sturdy shoes with grip, as the trail down is rocky and slippery when wet
- Sun protection, since there is little shade at the top
- Cash in small bills for entry, parking, drinks and snacks
- Water, although there are small food stalls near the entrance
There is a small community restaurant area with simple Oaxacan dishes. Prices are modest, and eating there supports the local communities who manage the site.
Combining it with other stops
Hierve el Agua sits at the end of the eastern Valles Centrales circuit. Most travellers combine it with:
- Mitla: a Zapotec and Mixtec site famed for its geometric stone mosaics.
- Mezcal distilleries: small family palenques along the road to Mitla offer tastings.
- Teotitlán del Valle: a weaving village known for wool rugs.

Practical notes
Altitude is about 1,800 m at the site, so take it slowly if you are arriving from sea level. The road is long, and anyone prone to motion sickness should sit at the front of the vehicle. Public toilets are available at the entrance for a small fee. Respect the signs about staying on the trails, because the formations are fragile.
Is it worth it?
Yes, particularly if you have two or more days in Oaxaca. The view from the pools over the Sierra is the main reason to go, and the day trip pairs well with Mitla and a mezcal tasting. If you are short on time, a combined tour is the most efficient way to see all three stops without arranging transport.
