A.T.M. Cave (Actun Tunichil Muknal) from Caye Caulker: How to Visit Belize’s Sacred Cave
A full-day journey from Caye Caulker that leads deep into Actun Tunichil Muknal’s subterranean rooms, where water, stone and Maya ritual converge. Expect river crossings, tight passages and the haunting Crystal Maiden in the main chamber.
The Experience
Before You Go
Bring secure water footwear
Sturdy water shoes with a firm sole make river crossings and wet boulder scrambles safer; flip-flops are not acceptable.
Keep electronics dry
Use a small dry bag for your phone and wallet—the cave is wet and pockets will fill fast.
Pace your hydration
Drink up before the hike; the combination of exertion and cool water can be deceiving indoors to your body.
Respect archaeological sites
Do not touch skeletal remains or cave formations; they are fragile and culturally significant.
