ATM Cave (Actun Tunichil Muknal) Guided Expedition from Belize City
Wade river crossings, stoop through limestone passages and stand before the "Crystal Maiden" on a full-day guided expedition into Actun Tunichil Muknal. This tour blends jungle hiking, Mayan history and protected cave archaeology into a demanding and unforgettable day.
The Experience
Before You Go
Wear quick-drying, grippy shoes
Expect wet river crossings and slippery limestone—closed-toe water shoes or lightweight hiking shoes with good tread are best.
Leave jewelry and loose items at the hotel
Small items can scratch formations or be lost in the cave; secure valuables before departure.
Hydrate and eat beforehand
It’s a long day with physical exertion and limited food options until the included lunch—carry a refillable bottle.
Respect no-touch zones
Do not touch or handle artifacts or formations; guides enforce this to protect archaeological material.
