The ancient Mayans believed that caves were portals to the underworld. Hence, caves played an important role in ancient religious practices. This reverence for caves has also led to the preservation of artifacts and other treasures contained within the caverns as the locals rarely entered the caves - let alone stole from them. You will see pottery and the remains of ancient human sacrifices that have been left untouched for hundreds of years! Just donít be surprised if the guide asks you to remove your shoes while in these sacred places.
