Duration1 dayDepartureOaxacaLanguage & groupBilingual · shared

A few hours from Oaxaca City, in the municipality of San Sebastián, lies a cave system worth a full day. This trip pairs a walk through ancient rock galleries with two optional extras for those who want more: an underground river and a cenote for swimming.

We leave at 8:00 AM straight from your hotel in downtown Oaxaca, at no extra cost, and return around 7:00 PM to the Zócalo. It's a good fit for anyone who enjoys nature, geology, and plans that step off the city's usual circuit.

Highlights

  • 🕳️ 420 meters of galleries: natural chambers and passageways decorated with stalactites and stalagmites, with a guide explaining how they formed.
  • 🌊 Underground river (optional): a 50-meter descent off the main path to the watercourse that carved the cave.
  • 💦 Cenote (optional): a dip in clear water inside the cave system, a great way to end the visit.
  • 🚐 No driving, no guesswork: round-trip transport, driver, and coordinator included from your hotel.

How the Day Unfolds

🚐 Departure from Your Hotel

We pick you up at your downtown Oaxaca hotel at 8:00 AM and drive toward San Sebastián with the mountain scenery alongside.

🕳️ Walking the Caves

Once we arrive we enter the caves and walk the 420-meter main route. Your guide explains how water and time shaped the stalactites and stalagmites, pointing out the most striking formations along the way.

🌊 Optional Extra: Underground River

If you're up for it, you can leave the main path and descend 50 meters to a river running beneath the rock, the same one that opened these caverns over thousands of years.

💦 Optional Extra: Cenote

The cave system also holds a cenote. Change into your swimsuit and swim as long as you like in its clear water.

🚐 Back to Oaxaca

We head back and reach Oaxaca's Zócalo at approximately 7:00 PM.

Frequently Asked Questions

1. Are the cave entrance fees included?

No. Entrance is about 95 MXN per person, and the underground river (~120 MXN) and cenote (~50 MXN) are optional. Everything is paid directly on site.

2. Do I need to know how to swim?

Not for the main cave walk. If you choose the cenote, it helps to be able to swim.

3. Is it suitable if I have claustrophobia?

The route includes enclosed spaces and sometimes narrow passages. If your claustrophobia is severe, consider it before booking; the river and cenote involve additional descents to greater depths.

4. Where do I leave my belongings if I do the river or cenote?

Bring a water-resistant backpack or dry bag for your phone, dry clothes, and towel. Anything you won't need during the exploration can stay in the vehicle.
