Embark on an Unforgettable Underground Adventure at ATM Cave

Commonly known as the Cave of the Crystal Sepulchre, ATM Cave is recognised as one of the most remarkable archaeological and natural wonders in Belize. The name itself translates to “Cave of the Stone Sepulchre” in the ancient Maya language. This cave is globally celebrated for its remarkable collection of ceremonial Maya artifacts, and it is particularly famous for containing the calcified skeleton known as the “Crystal Maiden,” which has captivated adventurers and historians alike.

• Location: Conveniently situated within the Tapir Mountain Nature Reserve, the cave is easily accessible between San Ignacio and Belmopan.

• Key features: The cave boasts impressive archaeological remains, vast cathedral chambers, an underground river, and stunning crystalline formations, all of which contribute to an exhilarating caving adventure.

Explore the Profound History and Spiritual Importance of the Maya in ATM Cave

The entrance to ATM Cave was first explored by the ancient Maya between 300–600 AD, but it was during the period from 700–900 AD that significant ceremonial activities unfolded within its depths. For the Maya, caves like ATM were regarded as spiritual gateways to Xibalba, the underworld, where essential rituals were performed to appeal for rain, fertility, and the favour of their deities.

• Sacrifice site: Archaeological excavations have uncovered at least 14 human skeletons, comprising both adults and children, alongside an array of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Numerous pots discovered within the cave feature intentional piercings designed to release their spirits, facilitating their transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to belong to a young female, appears to shimmer due to the accumulation of mineral deposits over the years[11][21].
• “Monkey Pot”: A distinctive and rare ceramic vessel, one of only four found throughout Central America[11].
