Embark on an Unforgettable Journey: Discover the Wonders of ATM Cave

Known locally as the Cave of the Crystal Sepulchre, ATM Cave is esteemed as one of Belize’s most remarkable archaeological and natural wonders. The name translates to “Cave of the Stone Sepulchre” in the Maya language. This cave is internationally acclaimed for its abundance of ceremonial Maya artifacts and is particularly famous for housing the calcified skeleton, affectionately known as the “Crystal Maiden.”

• Location: Nestled within the stunning Tapir Mountain Nature Reserve, conveniently situated between San Ignacio and Belmopan.
• National Geographic: Recognised as one of the world’s top ten most sacred caves[21].
• Key features: A treasure trove of archaeological remains, expansive cathedral chambers, an underground river, and breathtaking crystalline cave formations, all of which contribute to an exhilarating caving adventure.

Delve into the Rich History and Spiritual Significance of the Maya and ATM Cave

The entrance of ATM Cave was first explored by the Maya around 300–600 AD, but it was during the period of 700–900 AD that extensive ceremonial activities unfolded. For the Maya, caves like ATM served as spiritual gateways to Xibalba, the underworld, where significant rituals were conducted to summon rain, fertility, and the favour of their deities, underscoring the deep spiritual connection they had with these sacred spaces.

• Sacrifice site: Archaeological excavations have uncovered at least 14 human skeletons, including both adults and children, alongside countless ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Many pots discovered within the cave have been intentionally pierced to facilitate the release of spirits, allowing them to transition peacefully to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to be a young female, shimmers beautifully due to the accumulation of mineral deposits over the centuries[11][21].
• “Monkey Pot”: A distinctive and rare ceramic vessel, one of only four found in Central America[11].
