Actun Tunichil Muknal (ATM) Cave was rated by the Discovery Channel as the number one Sacred Cave in the world. Only accessible by swimming across a spring-fed pool, ATM contains hundreds of relics that have lain undisturbed for more than a millennia. At the far end of the cave lie the bones of more than a dozen men, women, and children who were ritually slaughtered by the ancient Maya.
This tour departs very early from Placencia. It is a 2.5-hour drive each way but it is so worth it. This is an experience of a lifetime.
