Step into one of the most legendary archaeological sites in Belize with a guided full-day adventure to Actun Tunichil Muknal (ATM) Cave, located inside the Tapir Mountain Nature Reserve in the Cayo District. Recognized as one of the most important Maya ceremonial caves ever discovered, the ATM Cave is home to ancient artifacts, untouched altars, and the famed Crystal Maiden—a fully intact skeleton calcified by centuries of mineral-rich water.
This immersive expedition reveals the Maya underworld, known as Xibalba, and is considered one of Belize’s most unforgettable cave experiences.
Begin your journey with a scenic drive from Hopkins Village, traveling through the Belizean countryside toward the Tapir Mountain Reserve. Once at the site, your licensed guide will lead you through a rainforest trail and across shallow streams before entering the cave system.
