Embark on a Unique Underground Adventure at ATM Cave

Locally known as the Cave of the Crystal Sepulchre, ATM Cave is distinguished as one of Belize’s most remarkable archaeological and natural treasures. The name translates to “Cave of the Stone Sepulchre” in the Maya language. This cave is globally recognised for its vast array of ceremonial Maya artefacts and, most notably, for housing the calcified skeleton famously referred to as the “Crystal Maiden.”

• Location: Conveniently situated within Tapir Mountain Nature Reserve, strategically positioned between San Ignacio and Belmopan.
• National Geographic: Honoured as one of the world’s top ten most sacred caves[21].
• Key features: This site boasts noteworthy archaeological remains, expansive cathedral chambers, an underground river, and stunning crystalline cave formations, all contributing to an exhilarating caving experience.

Dive into the Rich History and Spiritual Significance of the Maya & ATM Cave

The entrance of ATM Cave was first explored by the Maya around 300–600 AD, with significant ceremonial activities occurring between 700–900 AD. For the Maya, caves such as ATM were regarded as spiritual gateways to Xibalba, the underworld, where vital rituals were conducted to invoke rain, fertility, and the favour of their deities. This cave is a testament to the intricate relationship the Maya had with their environment and the spiritual beliefs that guided their existence.

• Sacrifice site: Archaeological excavations have uncovered at least 14 human skeletons, encompassing both adults and children, alongside hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Many pots discovered within the cave are intentionally pierced to release their spirits, enabling them to transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to be 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 identified in Central America[11].
