Set Off on an Extraordinary Expedition Through ATM Cave: Experience Your Unique Underground Adventure

Locally known as the Cave of the Crystal Sepulchre, ATM Cave is celebrated as one of the most remarkable archaeological and natural marvels in Belize. The name translates to “Cave of the Stone Sepulchre” in the Maya language, reflecting its significant cultural heritage. This cave is globally recognised for its impressive collection of ceremonial Maya artifacts and, most notably, for housing the calcified skeleton known as the “Crystal Maiden,” which mesmerises every visitor.

• Location: Nestled within the Tapir Mountain Nature Reserve, it enjoys a strategic position between San Ignacio and Belmopan, making it easily accessible for travellers.
• National Geographic: Celebrated as one of the globe’s ten most sacred caves[21].
• Key features: The cave boasts remarkable archaeological remains, expansive cathedral-like chambers, an underground river, and breathtaking crystalline formations, all of which enhance the exhilarating caving experience.

Discover the Rich History and Spiritual Significance of the Maya Civilisation & ATM Cave

The entrance of ATM Cave was initially explored by the Maya around 300–600 AD. However, it was during the period from 700–900 AD that notable ceremonial activities took place within its depths. For the Maya, caves such as ATM were viewed as spiritual gateways to Xibalba, the underworld, where crucial rituals were performed to invoke rain, ensure agricultural fertility, and gain favour from their deities.

• Sacrifice site: Archaeological excavations have revealed at least 14 human skeletons, including those of both adults and children, alongside hundreds of ceremonial pots, obsidian blades, and grinding stones[15][11].
• “Kill holes”: Numerous pots discovered within the cave have been deliberately pierced to release their spirits, aiding their transition to the Underworld.
• The “Crystal Maiden”: This iconic skeleton, believed to belong to a young female, appears to shimmer due to the accumulation of mineral deposits that have formed over the years[11][21].
• “Monkey Pot”: A distinctive and rare ceramic vessel, one of only four found throughout Central America[11].
