Actun Tunichil Muknal (ATM Cave): Exploring Belize’s Sacred Maya Underworld
Wade into a river-lit passage and step into a space where geology and ritual intersect. Actun Tunichil Muknal offers one of Belize’s most powerful cave experiences—where Maya artifacts and skeletal remains sit in near-original contexts beneath a canopy of stone.
The Experience
Before You Go
Wear grippy water shoes
Sections of the approach and cave floor are wet, slippery, and uneven—sturdy water shoes or old trail runners with good tread are best.
Pack a lightweight dry bag
Carry phone, ID, and any medications in a small waterproof bag; the tour involves river wading and splashes.
Hydrate before you start
The hike and cave entry are physically demanding; drink water at pickup and bring a refillable bottle in a dry bag.
Respect no-touch zones
Photography and touching are restricted in some chambers to protect delicate artifacts—follow guide instructions to avoid damage.
