Belize ATM Caving
Belize ATM Cave Tours
Named the #1 Sacred Cave in the World by National Geographic, Actun Tunichil Muknal (ATM), translated to Cave of the Crystal Sepulchre, is a 3-mile deep cave used as a sacred ceremonial site by the prehistoric Mayan people of Belize.
Actun Tunichil Muknal Caving
Actun Tunichil Muknal is also known as ATM – the Cave of the Stone Sepulcher is one of the most thrilling caving experiences Belize has to offer. This tour is a scenic 3 hour drive, followed by a 45 minute nature hike through dense jungle in the 6,700 lush acres of the Tapir Mountain Nature Reserve.
Interestingly, Actun Tunichil Muknal was named after the sacrificial chamber within the cave where one of the most famous human remains, known as “The Crystal Maiden,” was found. This is a skeleton of a teenage girl, probably a sacrifice victim, whose bones have been completely covered by the natural processes of the cave, leaving them completely intact with a sparkling appearance. The Mayas believed that gods, who provided rain and agricultural fertility, resided in this underworld. This cave offers a unique historical perspective; as you will see many of the artifacts are exactly as they were when the cave was first explored by archaeologists.
Throughout this hike, you will cross flowing streams and will witness the lush flora and fauna of Belize. At the entrance of the cave you will be outfitted with the necessary equipment preparing you for your journey into the underworld. It is a must see site, but is not for the faint of heart as it requires an intensive hike and swim within the depths of the cave. It involves swimming, crawling, and climbing. Although sacred to the Mayans you can also enjoy beautiful stalagmites, stalactites, and flowstones.
