Embark on a Unique Adventure: Uncover the Wonders of ATM Cave

Commonly known as the Cave of the Crystal Sepulchre, ATM Cave is distinguished as one of Belize’s most exceptional archaeological and natural wonders. The name translates to “Cave of the Stone Sepulchre” in the Maya language, and this cave is globally recognised for its extensive collection of ceremonial Maya artifacts. Most notably, it is home to the calcified skeleton known as the “Crystal Maiden,” which further enhances its allure.

• Location: Conveniently located within Tapir Mountain Nature Reserve, nestled between San Ignacio and Belmopan.
• National Geographic: Honoured as one of the world’s top ten most sacred caves[21].
• Key features: The cave boasts remarkable archaeological remains, vast cathedral chambers, an underground river, and stunning crystalline formations, all of which provide an exhilarating caving experience.

Explore the Deep History and Spiritual Significance of the Maya and ATM Cave

The entrance of ATM Cave was initially explored by the Maya between 300–600 AD. However, it was during the period of 700–900 AD that it became a focal point for significant ceremonial activities. For the ancient Maya, caves such as ATM were revered as spiritual gateways to Xibalba, the underworld, where essential rituals were conducted to summon rain, ensure fertility, and gain favour from their deities.

• Sacrifice site: Archaeological excavations have uncovered at least 14 human skeletons, which include both adults and children, along with hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Many of the pots discovered within the cave have been intentionally pierced to release their spirits, enabling them to transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, thought to be a young female, shimmers due to the mineral deposits accumulated over centuries[11][21].
• “Monkey Pot”: A unique and rare ceramic vessel, one of only four discovered in Central America[11].
