Set Off on an Unforgettable Underground Adventure at ATM Cave: Your Unique Journey Awaits

Locally known as the Cave of the Crystal Sepulchre, the ATM Cave stands out as one of the most impressive archaeological and natural marvels in Belize. The name translates to “Cave of the Stone Sepulchre” in the Maya language, underscoring its profound cultural significance. This cave is globally acclaimed for its extensive collection of ceremonial Maya artifacts, including the extraordinary calcified skeleton known as the “Crystal Maiden,” which fascinates every visitor who steps into its depths.

• Location: Tucked away within the Tapir Mountain Nature Reserve, it enjoys a prime location between San Ignacio and Belmopan.
• National Geographic: Acknowledged as one of the globe’s ten most sacred caves[21].
• Key features: The cave boasts remarkable archaeological remains, vast cathedral-like chambers, an underground river, and stunning crystalline formations, all of which contribute to an exhilarating caving experience.

Discover 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. However, it was during the period from 700–900 AD that substantial ceremonial activities took place within its confines. For the Maya, caves like ATM were considered spiritual gateways to Xibalba, the underworld, where vital rituals were performed to invoke rain, ensure fertility, and seek favour from their deities, thus highlighting the cave’s profound spiritual importance.

• Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, including both adults and children, accompanied by hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Many pots discovered within the cave have been intentionally pierced to release their spirits, facilitating their transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to be a young female, appears to shimmer due to the build-up of mineral deposits over time[11][21].
• “Monkey Pot”: A unique and rare ceramic vessel, one of only four discovered across Central America[11].
