Set Off on an Extraordinary Adventure: Discover the Mysteries of ATM Cave

Locally known as the Cave of the Crystal Sepulchre, ATM Cave is celebrated as one of the most remarkable archaeological and natural wonders in Belize. The name translates to “Cave of the Stone Sepulchre” in the Maya language, showcasing its deep cultural significance. This cave is internationally recognised for its extensive collection of ceremonial Maya artefacts and, most famously, for housing the calcified skeleton known as the “Crystal Maiden,” which enchants all who venture within.

• Location: Conveniently situated within the Tapir Mountain Nature Reserve, it lies between San Ignacio and Belmopan, making it easily accessible for visitors.
• National Geographic: Acknowledged as one of the globe’s ten most sacred caves[21].
• Key features: Featuring incredible archaeological remnants, vast cathedral-like chambers, an underground river, and breathtaking crystalline formations, all of which contribute to an exhilarating caving experience.

Uncover the Profound History and Spiritual Significance of the Maya & ATM Cave

The entrance of ATM Cave was first explored by the Maya between 300–600 AD. However, it was during the period from 700–900 AD that important ceremonial activities occurred within its depths. For the Maya, caves like ATM were considered spiritual gateways to Xibalba, the underworld, where vital rituals were conducted to invoke rain, ensure agricultural fertility, and seek favour from their deities.

• Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, comprising both adults and children, alongside hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Numerous pots discovered within the cave have been deliberately pierced to release their spirits, aiding their passage to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to be that of a young female, appears to glimmer due to the accumulation of mineral deposits accumulated over centuries[11][21].
• “Monkey Pot”: A unique and rare ceramic vessel, one of only four found throughout Central America[11].
