Actun Tunichil Muknal (ATM) Cave Tour from San Ignacio — Explore Belize’s Sacred Underworld
Wade through jungle rivers and step under an hourglass entrance into one of Belize’s most sacred and physically demanding cave experiences. This guided tour to Actun Tunichil Muknal combines geology, Mayan ritual history, and hands-on spelunking for an unforgettable day trip from San Ignacio.
The Experience
Before You Go
Bring grippy water shoes
Expect ankle-to-waist-deep crossings and slippery limestone—rubber-soled shoes with good tread protect you and aid traction.
Wear quick-dry layers
A swimsuit under lightweight layers speeds drying and keeps you comfortable during the return drive.
Protect the artifacts
Do not touch formations or skeletons; oils and breath accelerate deterioration and guides will enforce penalties.
Pack a dry bag and fresh clothes
You’ll get wet; store electronics in a dry bag and change immediately after the tour to avoid chills.
