Inside Belize's Actun Tunichil Muknal (ATM) Cave: Jungle Hike, Swim & the Crystal Maiden

The Experience
Before You Go
Plan for mainland pickup
This tour departs from Belize City; if you’re on an island factor in ferry or flight time to avoid missed departures.
Wear grippy water shoes
Stream crossings are knee to waist deep and the cave floor is slick — closed-toe water shoes or light hiking shoes with drainage are best.
Pack a lightweight dry change
Bring a small dry bag with clothes and electronics; you’ll be wet after the cave swim and a quick change makes the return ride comfortable.
Respect no-touch rules
Do not touch artifacts or skeletal remains; oils and contact accelerate deterioration and guides will enforce preservation rules.
Local Knowledge
Hidden Gems
- •Listen for howler monkeys during the morning hike — they sound closer than they are and mark territories in the canopy.
- •Ask your guide to point out medicinal plant uses found along the trail — local herbal knowledge is often shared during the walk.
Wildlife
- •Howler monkey
- •Toucan
Conservation Note
The cave is delicate — operators limit group sizes and enforce no-touch rules to protect artifacts and skeletal remains; avoid using flash close to fragile surfaces.
ATM was a ritual cave for the ancient Maya; offerings and human remains were placed in chambers as part of ceremonies linked to agriculture and the underworld.
Photographer's Notes
- • At the cave mouth looking back at the jungle opening
- • Across the spring-fed pool before the swim
- • From the upper rim of the ceremonial chamber (as allowed by guides)

Common Questions
How long is the hike to the cave entrance?
The jungle hike to the cave entrance is about 30 minutes over uneven ground with several stream crossings.
Do I need to be able to swim?
Yes — you’ll swim across a short spring-fed pool (10–15 seconds) to enter the cave; basic swimming ability is required.
Are there age restrictions?
Operators accept most ages but young children must be strong swimmers and supervised; inquire with the operator for specific age guidelines.
Can I touch the Crystal Maiden or artifacts?
No — touching is strictly forbidden to prevent damage; follow your guide’s instructions at all times.
What time of year is best to visit?
Dry season (roughly December–April) offers lower water levels and easier crossings, though the cave is open year-round with appropriate caution in wet months.
How do I get to the meeting point from Ambergris Caye?
Take the water taxi or a short flight to Belize City, then use the provided pickup at the ferry terminal or the listed meeting point; allow extra transit time for connections.
