Follow the steps of ancient Mayans and explore one of the most impressive burial sites in the region.
Enter the mouth of Actun Tunichil Muknal. The ancient Mayans held many sacrificial offerings in this unearthly cave system, and you will swim and squeeze your way between passages to see the evidence.
Blood-letting blades, finger bones, and complete skeletons lie untouched after thousands of years.
The tour culminates with the “crystal maiden”—the skeleton of a young woman, now encrusted with calcium, whose remains emit a surreal, glittering facade.
