Visit a Mayan cave tomb
Actun Tunichil Muknal cave hides its mysteries deep within its intricate paths. After hiking and wading for over a kilometre within its subterranean depths, you’ll finally reach Mayan tombs where 1,000-year-old ceramics and human remains lie in their original undisturbed state. The best known of the entombed skeletons is that of a teenage girl known as the ‘Crystal Maiden’ – thanks to centuries of calcification, her bones appear to sparkle.
