Delicious and distinctive food. Deep, smoky mezcals. Artisanal crafts passed down through generations. Living cultural traditions layered over centuries of history.
The Mexican state of Oaxaca draws travelers for these reasons and more. Even with a full week based in Oaxaca City, it would be nearly impossible to cover all the bases.
Lesser-known experiences like this Oaxaca prehistoric caves tour in the Central Valleys require intention and more effort to seek out.
I like to see the main landmarks but also want to save time for something that doesn’t always get the limelight. The quieter sites have unexpected stories bubbling beneath the surface that often lead to serendipitous moments.
After a six-day breathwork retreat near Tepoztlán, I found myself wanting to connect more deeply with Oaxaca’s ancient roots.
I sought something that touched on its indigenous history and spiritual traditions in a more tangible way. Then I discovered the Oaxaca prehistoric caves tour that was the perfect fit.
This Oaxaca prehistoric caves tour near Mitla quickly became one of the most meaningful cultural experiences I had in the Central Valleys.

Choosing the Tour
You may recall that I got my Sak Yant tattoo in Thailand in November 2024 with Where Sidewalks End (WSE).
WSE has many excursions in Oaxaca, but I liked the idea of combining history and food in a single tour.
Visiting some of the prehistoric caves in the Tlacolula valley may take a full day of hiking in the elements. I chose this tour because of the variety of activities included and a more moderate hike. Of course, having had a positive experience with WSE in Thailand, it was an easy choice.
The Oaxaca Prehistoric Caves Tour Experience
On Sunday morning, February 8, 2026, our guide and driver Christian picked us up at our hotel around 9AM. We swung by to get Victor, another guide who works with WSE, and away we went.
Naturally, this Oaxaca prehistoric caves tour in the Central Valleys focuses on caves. As I alluded to above, that’s not all we would be doing.
Located east of Oaxaca City near Mitla, the caves sit within the same broader archaeological landscape as Monte Albán and other Zapotec sites.
Designated a UNESCO World Heritage Site in 2010, these valleys hold just under 150 distinct caves.
We visited one site that contained five separate caves, each with unique markings, historical finds, and cultural significance. The site is located on private land even though the access road is just off the main highway.
Agriculture and Ancient Maize
The discovery of an early form of maize (corn) known as teosinte or teocintle (teocintli, in Nahuatl) challenged the assumption that the Zapotecs (and Mixtecs) arrived much later than the Olmecs. Some of the corn kernels were over 6,000 years old.
Archaeologists and anthropologists learned a lot about early Mesoamerican agriculture and maize domestication by what they found left behind. They found evidence illustrating these caves were a bridge between hunter-gatherer societies and the beginning of the agricultural age.
The “three sisters” crops of maize, squash, and beans were grown using a system known as milpa. This is essentially a field where all crops are grown together.
Teosinte still grows in the area, but the modern corn we are familiar with is preferred due to its size and texture.
Maize is of such significance here, I wanted to set the stage.
Yagul and the Wider Archaeological Landscape
The caves are part of the same archaeological landscape as Yagul and Mitla, recognized by UNESCO for early evidence of plant domestication.
Before we arrived at the main cave site, we passed by Yagul. This former city-state dates back to 500 BC and had a population of over 6,000 at its peak. This site is known for its Palace of the Six Patios and a ceremonial ball court.
From the highway where we pulled over, we could easily see a white painting on the side of the rock. Just slightly above it sits one of the edges of the fortress.
Ree Bilie and the Oaxaca Prehistoric Caves
There are many names associated with this prehistoric cave site, but I’m going with what we saw on the welcome sign: Ree Bilie. That is the local Zapotec language name for this particular site.
Managed by the local community and not the National Institute of Anthropology and History (INAH) like Monte Albán, Ree Bilie felt more authentic and relaxed.
After parking in a small dirt lot, the local guide Davíd met us for the tour. Our WSE guide Christian translated Davíd’s Spanish, although I was proud that I could understand at least 70% of it.
On the walk to the steps up to the first cave, we learned about some of the native vegetation including agave cactuses. Some of the plants here are the same ones that are used to make the legendary mezcal in the area.
Bilie Gäal, Bilie Naa, and Bilie Nacäy
Cueva del Anochecer is the Spanish name for the first cave we approached, which translates as “Cave of Dusk.” In the Zapotec language, “gäal” means “dusk,” so Bilie Gäal is the local name.
Waters that used to cover this area gradually lowered and through erosion formed most of these caves. Saltpeter deposits stained pocked areas of the cave ceiling.
The Cueva de las Manos (Bilie Naa) or “cave of the hands” got its name because of the red handprints marking the entrance. The markings illustrated to potential intruders that the cave was already occupied.
Cueva Oscura (Bilie Nacäy) or the “dark cave” is pretty self-explanatory. Here we saw a small display of the teosinte in contrast with a modern ear of corn. There were also tools fashioned out of rock that the Zapotec settlers used to carve, cut, grind, or shape things.
Copal Trees
Continuing up the hillside to the cave with the best views, we passed some red copal trees. We smelled the berries, wood, and resin that was leaking from the bark.
The trees reminded me of the retreat because copal was burned each day as a ritual before we entered the space.
The next cave turned out to be the initial entrance to Bilie Nadii (Cueva de las Pinturas). This was likely the home of the chief or most powerful leader of the people who lived here. The view of the surrounding area was the best while also providing refuge.
Casting Maize Seeds
On a ledge overlooking the surrounding landscape, we saw a cross outlined in corn kernels. Our guide Christian explained that he had done that as part of a ritual.
The symbol was not the Christian cross, but rather an Ayöök (Ayuujk or Mixe) tradition signifying the four directions: air (north), fire (east), water (south), and dirt (west). The circle around the cross represents the path of the sun around Earth.
Arranging the kernels is part of a more complex spiritual practice called xëë maywë. Once the cross pattern is arranged, remaining kernels are used as a type of prayer.
One can toss the seeds into the air or stack them in a cairn in the cave while setting an intention. The idea is to ask for permission, find answers, or let go of something. The casting of the kernels allows an alignment with nature, releasing the burden to the Earth.
So much of that resonated with me, as I’ve been going through a period of letting go and transformation. Casting the corn kernels connected me more deeply with the caves and the surrounding land, even though I had no real ties to the Mixe culture.
That’s part of the beauty of travel, though. You don’t really need to possess knowledge as much as feel the place. It doesn’t always happen, but when it seems divinely inspired, it is indeed special.
The Cave Paintings of Bilie Nadii
Finally, the pièce de résistance and highest cave on our tour: Cueva de las Pinturas (Bilie Nadii). This cave was smaller but had the best preserved concentration of paintings of all the caves.
Davíd unlocked the gates, undoubtedly placed there to protect the area from vandals and looters. The red paintings illustrated several cultural rituals, with images from animals to corn, dating back as far as 8,000 years.
Archaeologists believe some of the painting rituals may have involved psychotropic plants, though interpretations vary.
One specific handprint at the back was the reverse of the other type. Instead of a true print, it was an image of a traced hand. This implied that the hand belonged to someone of importance.
After one final view on the edge of a promontory, we descended back down the mountainside via an alternate route.
Mole Tasting and Culinary Traditions
After a vigorous hike to and from the caves, we worked up quite the appetite. Fortunately the next thing on the itinerary was an extravagant mole tasting in a nearby village.
Mole (pronounced “MO-lay”) might be familiar to you as a chocolate sauce, but that’s not accurate. Actually, “mole” is really a basic term for a type of sauce that originated here.
One of the most popular moles is the dark brown mole negro that often contains cacao, but there are many other varieties.
The Land of Seven Moles
Oaxaca is often referred to as the “land of seven moles” due to the iconic and distinctive types found here. There are hundreds of variations, though.
The sauces vary depending on color, spice, thickness, and ingredients. Local chiles such as chilhuacle and guajillo add to the uniqueness.
Here are the core seven moles:
- Negro (Black): The most famous, complex, and dark, often sweet and savory with chocolate and chiles.
- Rojo (Red): Similar to coloradito, rich and red.
- Amarillo (Yellow): Bright orange/yellow, lighter, often spicy, and thickened with masa (dough or flour made of corn that has been soaked in alkaline solution).
- Verde (Green): Fresh, herb-forward, using tomatillos, cilantro, and pumpkin seeds.
- Coloradito (Ruddy): A brick-red, slightly sweet mole.
- Manchamanteles (“Tablecloth Stainer”): Fruitier, sometimes featuring pineapple or plantains.
- Chichilo: A smoky, intense, and rare mole often using avocado leaves.
Remember, these are just the overall categories. There are several “moles negros” for example. Think of them like sauces or gravies that would obviously differ based on who’s preparing it and what special touches or tweaks they might make to each recipe.
The Mole Tasting Experience
I won’t spoil all the surprises here, so I’ll skip going over each and every mole we tried.
After a welcome tostada, they brought out 14 little bowls and a stack of tortillas so we could try each mole before ordering.
The lunch came with a choice of up to four moles paired with 1-4 meat options: beef, chicken, pork ribs, or pork shoulder. This allowed for a huge variety of combinations. For example, three different moles with chicken or two with beef and two different moles with pork shoulder, etc.
It was really hard to choose! I picked only three because I knew I wouldn’t be able to eat that much after sampling all the moles multiple times.
The kitchen staff knows what moles combine well and which ones are better not bleeding together. The chef separates such moles with a wall of rice so they don’t cross-contaminate on the plate.
Really, you can’t go wrong here, even if you do mix them together. While I loved trying the fruity moles and the green ones, I stuck with a pungent black, corn, and coloradito.
The meal also comes with a pitcher of agua fresca (fresh juice). The flavor of the day was passionfruit!
Dainzú Archaeological Site
Completely stuffed and groggy, we headed back towards Oaxaca and our final destination of the day.
Dainzú is an archaeological site that used to be part of INAH, but was turned back over to the local community to manage. Compared to Monte Albán and other sites, it’s quite small.
Many scholars think it predates Monte Albán by about 200 years.
One theory about Dainzú was that it became a destination for royalty and other nobility to attend the biennial ball games. There are still a lot of unknowns about the origin of this site and many others in the area.
Much like other sites, the Zapotec ball court is a fixture at this location. Another interesting component here is the Templo Amarillo, or “yellow temple” because of its ochre paint.
Dainzú has a decent collection of stone relief etchings as well as an ingeniously designed water channelization system. The ancient plumbing delivered water from the top of the upper temple down the hill to the main plaza.
There were only three visitors when we arrived, and then we had the place to ourselves. I enjoyed the chance to explore without feeling rushed.
The only downside to the day was that we were unable to visit the Tree of Tule, which was an option on the agenda. Due to the time it took for us to climb, eat mole, and explore Dainzú, it was too late and we were completely exhausted anyway.
Practical Tips for Visiting Oaxaca’s Prehistoric Caves
I really wanted to provide some in-depth details on what you might want to know to prepare for this tour so you can determine if it’s the right option for you.
What to Bring
WSE provides some suggestions of what to bring, but I thought I’d reiterate them and add a few of my own recommendations.
Here are the essentials:
- Hiking shoes or thick-soled sneakers
- Water and maybe some hydration packets
- Sunblock/sunscreen
- Wide-brimmed hat or cap
- Cash, in addition to the local payment (in case you want to buy something)
These are optional items, depending on your situation or the season:
- Walking pole or stick to assist with steep climbs and unsteady terrain
- Light jacket or sweater, depending on the weather (possibly for the first hour or two)
- Umbrella or raincoat in summer months
- Bug spray or insect repellent
- Buff or sweatband
- Backpack to carry any items you bring
- A light snack in the morning if you didn’t eat (but save room for the mole!)
I wore loose fitting long pants instead of shorts. The locals were all dressed in long sleeves and long pants with wide-brimmed hats for sun protection, so you may want to do the same. I wish I had brought my safari hat instead of just the baseball cap.
Physical Difficulty
There’s no doubt about it, you will need to be able to climb up a hill. It’s not a long climb, but anyone with mobility issues may find it challenging. It is not wheelchair accessible at all.
The climb is fairly vertical, so be aware of your limits and rest as needed. We passed a group of senior citizens. One woman had fallen, although she was fine.
You’ll need to climb up some uneven and rocky terrain. The caves themselves have bumpy surfaces with a few sharp edges.
Some of the steps up to the caves are loose or have metal reinforcements that jut out, so sturdy shoes are a must.
One of the caves has a low ceiling, so you will need to bend almost 90 degrees to walk into the cave before you can stand up. If you aren’t able to do that, you should still be able to experience the cave from the outside as long as you can make the climb up to begin with.
Other Considerations
Regardless of the weather, it’s likely to be at least warm. It was particularly dusty and dry when we visited, so I found myself even thirstier than usual.
There was a toilet facility near the parking lot, but Davíd had to check to make sure there was running water before we could use it.
To flush, we filled a bucket of tap water and manually poured it down the toilet bowl. No big deal, but just something to be aware of. There are no other toilet facilities, so be forewarned!
The caves are located at an elevation of around a mile high (1,500 to 1,800 meters), so be mindful of the physical effects of altitude.
Dainzú has some of the traditional long steps associated with ruins in this area. To see the beginning of the water drainage system, you have to duck into a smaller opening and then immediately climb down some steep steps.
We are in moderate shape and it wasn’t so bad. However, the day exhausted us.
Best Time to Go
Much of Mexico can get really hot in the spring and summer months. Late summer and early autumn can bring rains, although June can as well.
I would avoid April through June, as that will be the hottest time. Climbing up to the caves would be pretty uncomfortable and could put you at risk for heat stroke.
Winter time is probably the coolest time to go, so that would be my recommendation.
Who This Tour Is For
Anyone who is curious about diving a little deeper into Oaxacan culture should consider this tour.
This is especially suited for more adventurous travelers who want to see something different and less crowded. It’s a great combination of culture, physical exercise, and local cuisine.
I would say it’s NOT for anyone who relies on a mobility device like a wheelchair or has any other severe mobility restrictions.
For anyone with super specialized diets or food allergies, the mole tasting may require some modifications. It’s possible to prepare something vegan-friendly, but you must request it in advance. WSE will ask you ahead of time about any dietary restrictions, so you should be fine.
To be honest, I would have been happy just dipping tortillas in the sauces all afternoon, but the meat choices were great!
Is It Worth It?
Absolutely! The cost varies by the number of people on the tour, with a maximum of six people per group. The price becomes more attractive with a larger group size due to shared expenses such as transportation and guide fees for this private tour.
At the time we visited, the price was $125 USD for one person or $75 USD per person for two people. An additional local payment of 500 pesos (MXN) must be made during the tour. This payment goes towards the management of the cave site and Dainzú, which are both handled by the local community.
Since it was just us two plus Christian and Victor in the car, the ride was very comfortable and we had a lot of flexibility with the time. It is a private tour, so you will not be with strangers.
Very few people visit these caves, so it was extra special to be able to include this on our Oaxaca itinerary. Add in the mole tasting and another less visited archaeological site, and you’ve got the chef’s kiss of the road less traveled.
Of course, I would have liked to have seen the Tree of Tule, which is some 2,000 years old.
From pickup to the final drop-off, the day lasted nearly eight hours. The tour is usually around six hours and we felt satisfied with what we did, so we’ll save the tree for another trip.
It’s safe to say, we would love to return to Oaxaca!
