Its original name is Oxtimaxal Sur Cave and it is the closest one to Cuetzalan.

The cave has a depth of 80 meters, vaults between 30 and 60 meters high, and the tour is 400 meters long. However, the most peculiar feature of the cave is its acoustics, as even a drop of water falling on the rocks resonates throughout the cave.

It has railings, spotlight illumination, and parking, making it one of the most accessible and easy-to-explore caves in the area. However, it is recommended to wear waterproof and slip-resistant footwear.

In its surroundings, there are beautiful camping areas, cabins, and establishments that provide food.
