The name means "cave with an underground river inside," and the main cave ( of three ) is more than 600 yards long, with a magnificent vault. Discreet illumination and easy walking paths make visiting the caves comfortable, without appearing to alter them much from their natural state.

The main attraction on the park is a dry cave, 540 meters in length, which has thousands of stalactites and stalagmites, calcium carbonate columns, and tree roots which penetrate the limestone until they reach the subterranean water level. Inside this cave there is a beautiful subterranean "cenote", or water filled sinkhole, of crystalline water with a vault saturated with stalactites.

When you go out of the cave you can watch white tail deer, pheasant, wild turkeys, wild boar, parrots, monkeys, etc. All of these species of the region’s wild life can be observed in their natural habitat, without confinement. In this area you can find a Snack bar, where you could enjoy a delicious cold beer, a soda or a Mexican dish.

This park also has a "serpentario", snake observatory, the most complete of Mexico’s southeast, with 15 species typical of this region.

Surrounding the cave are nature trails throughout the 988 acre park, where spotting of deer, spider monkeys, iguanas, and wild turkeys are common. A small informal restaurant and gift shop are also on-site.

Tours have no set times-guides are available to take you when you arrive-and the maximum group size is 20.
