Actun Tunichil Muknal (ATM Cave) | From Placencia

Enter the Maya Underworld (Xibalba). Voted by National Geographic as the #1 Sacred Cave in the World, the ATM Cave is more than a tour; it is an expedition.

The Experience

The Journey

Because this site is deep in the Cayo District, we start early. You'll travel in comfort up the Hummingbird Highway, passing the most scenic landscapes in Belize before arriving at the Teakettle Village trailhead.

The Hike & Swim

The adventure begins with a 45-minute jungle hike that includes three river crossings (yes, you will get wet immediately!). At the cave entrance, you swim into the mouth of the mountain. Inside, you'll navigate water and rock formations until you reach the dry "Cathedral" chamber.

The Discovery

In the main chamber, you remove your shoes and walk in socks to protect the artifacts. You are walking among history—hundreds of Maya pots, tools, and ceremonial items lie where they were left over 1,000 years ago. The finale is the Crystal Maiden, the sparkling, calcified skeleton of a young woman sacrificed to the gods.

Frequently Asked Questions

1. Why are cameras banned?
Years ago, a tourist dropped a camera and broke an ancient skull. Since then, the Belize Institute of Archaeology has strictly banned all cameras and phones inside the cave. This allows you to disconnect and truly experience the moment.

2. Do I need to know how to swim?
You should be comfortable in water. The entrance requires a short swim (about 20 feet) in deep water. Life jackets are available if needed, but you will be wading through water for much of the trip.

3. Is it claustrophobic?
Most of the cave is massive (like an aircraft hangar). There is one slight, tight squeeze at the neck, but your guide will help you through it. If you have severe claustrophobia, let us know.

4. Is it safe for kids?
Minimum height is 40 inches. We generally recommend this for ages 8+ who are active and comfortable with hiking and darkness.
