ATM Cave (Actun Tunichil Muknal) | From San Ignacio
The Sacred Underworld. This is the most famous adventure in Belize. Actun Tunichil Muknal (Cave of the Stone Sepulchre) is not a show cave with lights and walkways—it is a wild archaeological site. You will hike through the jungle, swim into the cave mouth, and trek through underground rivers to reach the dry chamber where Mayan ceramics and human skeletal remains have laid untouched for over 1,000 years.
⚠️ Strict Rules (Government Enforced)
| 🚫 NO CAMERAS / PHONES: Absolutely no photography is allowed inside the cave. This is strictly enforced to protect the artifacts. 🧦 SOCKS REQUIRED: You must have a pair of socks to walk in the “Dry Chamber” (shoes are removed). |
The Experience
The Trek
We drive 45 minutes from San Ignacio to the Tapir Mountain Nature Reserve. Then, we hike 45 minutes through the jungle, crossing the Roaring Creek river three times (waist deep).
The Cave
You swim a short distance into the cave entrance (life vests provided). Then, it’s a mix of walking in water and climbing over rocks. The formations are sparkling and immense.
The Cathedral
Deep inside, we climb a ladder to the upper chamber. Here, we see the “Crystal Maiden”—the calcified skeleton of a sacrificial victim—and hundreds of ancient pots.
The “Private” Difference
The ATM cave can get crowded with groups bumping into each other. On a private tour, we can adjust our start time to try and find a quieter window, giving you a more spiritual and immersive experience.

Frequently Asked Questions
1. How fit do I need to be?
Moderate fitness is required. You must be able to hike 45 mins, swim 20 feet, and climb over rocks.
2. Is it claustrophobic?
Mostly no. The chambers are huge (like a cathedral). There is one small squeeze called “The Neck” but the guide helps you through.
3. Can kids go?
Minimum height is 40 inches. We recommend it for adventurous kids 8 and older.
4. Why no cameras?
A tourist dropped a camera onto an ancient skull years ago and broke it. Since then, the government banned all cameras.
5. What do I wear?
Shorts and a t-shirt (quick dry is best). You will be wet the entire time inside the cave.
6. Is the water cold?
It is cool (70-75°F), but you are moving constantly so most people stay warm.
