Actun Tunichil Muknal (ATM) Cave: Full-Day Mayan Ritual Caving Tour from Belize City
Swim a clear channel into the heart of ATM and follow a licensed local guide through chambers where stalactites, flowstones and ancient Maya offerings remain. This full-day caving tour combines geology, ritual history and demanding physical passages — bring fitness, waterproof footwear and respect.
The Experience
Before You Go
Footwear that grips and drains
Wear close-toed waterproof hiking shoes or sturdy sandals with good tread; slick rock and river crossings demand secure footing.
Bring a full change of clothes
Expect to get wet and muddy — pack dry clothes and a zip-top bag for the return drive.
You must be a confident swimmer
Several swims through clear passages are required; weak swimmers should reconsider the trip.
No cameras inside the cave
Respect site rules: cameras and flash are prohibited to protect artifacts and the experience.
