Exploring Actun Tunichil Muknal (ATM) Cave: Belize's Sacred Underworld Day Trip from Belize City

The Experience
Before You Go
Wear sturdy water shoes
Old sneakers or dedicated water shoes give traction on slippery rock and protect toes during stream crossings.
Bring a dry change of clothes
You’ll be wet from the forest approach and cave wades—pack a towel and a dry outfit for the ride home.
Respect the archaeology
Do not touch bones, ceramics or formations; guides will point out where photos are allowed and where they are not.
Bring snacks and hydrate
Although lunch is included, carry a water bottle for the trail—cave air and jungle humidity dehydrate quickly.
