The ATM Cave is a "must do" tour experience- and it's easily accessible!! The tour starts with a 45 min hike through the jungle in the Tapir Mountain Nature Reserve. It is a great way to soak in the majesty of the surrounding jungle. You will cross three rivers as you wind your way through the jungle to the mouth of the cave. The tour duration is approximately 3 hours. Bring along a change of clothes as you will be completely wet by the time the tour is over. Understanding why this cave was of such sacred importance to the Mayas requires an understanding of their spirituality. In the Maya religion, the gods of agriculture, rain, and fertility were believed to reside in the underworld. It would only seem natural that the ATM Cave, with its seemingly endless pits, would be seen as a potential gateway to the underworld. By making human sacrifices within the cave, they could appeal to these important gods practically at their front door.
Guests should dress as if preparing for a hike, bringing comfortable clothes and sturdy closed-toe shoes. Also, socks are mandatory for walking inside the cave. Bear in mind that no cameras are allowed within the cave. The prohibition of cameras prevents damage to remaining skeletons and artifacts and preserves ATM for future generations.
