ATM Cave Tour from Belize City

Actun Tunichil Muknal — the ATM Cave — is in the Tapir Mountain Nature Reserve in the Cayo District, roughly 90 minutes to two hours west of Belize City on the George Price Highway. It is the longest and most physically demanding day in the Belize City catalog. Actun Tunichil Muknal is one of Belize’s best-known cave and archaeological experiences. Plan 8 full hours from pickup. This full-day route is not recommended for cruise schedules.

After the drive west, the local guide leads a safety briefing and gear preparation at the trailhead — about one hour from San Ignacio. The cave approach involves three river crossings on foot, then swimming into the cave entrance. Inside Actun Tunichil Muknal, passages are wet, rock surfaces uneven, and some sections require climbing over boulders or moving through low passages. Mayan pottery vessels and skeletal remains lie in their original positions — preserved as part of a protected archaeological reserve managed by the Institute of Archaeology Belize.

The Crystal Maiden — a fully calcified human skeleton in the cave’s upper dry chamber — is the most widely known feature inside Actun Tunichil Muknal. In the dry chamber, remove your shoes and wear socks to protect the cave surface. No cameras, phones, or recording devices are permitted inside — enforced by the local guide without exception. This is a preservation requirement, and guests who cannot comply should choose a different tour before making a deposit. Xibalba, the Mayan underworld, finds its most literal expression in caves like this one.

The return follows the same trail and three river crossings. Time to change and dry off before the drive back to Belize City. The full cave experience — trail in, time inside, trail out — takes four to five hours. ATM Cave suits physically fit guests who are comfortable with river water, enclosed rocky spaces, and sustained effort over a long day.

A licensed Belize Tourism Board guide and air-conditioned vehicle are included for the full route. Choose an available date and your travelers to review the options and total online.
