Actun Tunichil Muknal “cave of the stone sepulcher” was first discovered in 1989 located in the Tapir Mountain Reserve in the Cayo District near the village of Roaring Creek. This popular cave is rated as the #1 cave in Central America by National Geography and listed as the top things to do in Belize.

The ATM Cave is known to be used by the Mayans for ceremonial purposes during the classic period. Most of the ceremonies or rituals were held at the entrance of the cave. The interior of the cave was considered to be more sacred and closer to the Mayan rain God, Chaak. Towards the end of the classic period it is believed that the rituals were held deeper into the interior of the ATM as a result of drought thus contributing to the collapse of the Mayan civilization.

The natural geological wonder of crystalline stalactites and stalagmites formations are not the only remarkable thing about the ATM. This 5-kilometer-long museum if filled with ancient Mayan artifacts and has over 14 human remains of men, women and children.
