Begin Your Extraordinary Adventure at ATM Cave: Uncover the Mysteries Beneath the Surface

Locally known as the Cave of the Crystal Sepulchre, ATM Cave is hailed as one of the most remarkable archaeological and natural wonders within Belize. Its name translates to “Cave of the Stone Sepulchre” in the Maya language, reflecting its rich cultural legacy. The cave is globally celebrated for its extensive array of ceremonial Maya artefacts, and most notably, it is the resting place of the calcified skeleton known as the “Crystal Maiden,” a discovery that leaves a lasting impression on all who venture inside.

• Location: Nestled deep within the Tapir Mountain Nature Reserve, the cave is conveniently located between the bustling towns of San Ignacio and Belmopan.
• National Geographic: Included among the world’s ten most sacred caves, this designation underscores its cultural and historical significance[21].
• Key features: The cave boasts incredible archaeological remains, expansive cathedral-like chambers, an underground river, and breathtaking crystalline formations, all contributing to an exhilarating caving experience.

Discover the Profound Legacy and Spiritual Significance of the Maya and ATM Cave

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

• Sacrifice site: Archaeological investigations have revealed at least 14 human skeletons, comprising both adults and children, alongside numerous ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Many pots discovered within the cave have been deliberately pierced to release their spirits, thus aiding their transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, thought to be that of a young female, appears to glimmer due to the build-up of mineral deposits over the years[11][21].
• “Monkey Pot”: A unique and rare ceramic vessel, one of only four discovered across Central America[11].
