Before you embark on this once-in-a-lifetime journey into Belize’s most famous sacred cave, it’s important to understand the physical and environmental demands of the experience. The ATM Cave tour is not your typical walk in the park—but that’s part of what makes it so rewarding.

Claustrophobia Awareness

While much of the cave is open and spacious, there are moments where you’ll squeeze through narrow chambers or low ceilings. If you suffer from severe claustrophobia or panic in dark, enclosed spaces, this tour may feel overwhelming. However, the presence of a professional guide, continuous movement, and natural light from headlamps can help many people feel at ease.

Swimming Requirements

To enter the cave, everyone must swim across a short river section—about 15–20 feet long—into the dark entrance. Life jackets are provided, and the water is usually calm. Non-swimmers often manage by dog-paddling or holding on to the guide. Throughout the cave, you’ll wade and walk through ankle-, waist-, or chest-high water depending on the season.

Physical Fitness & Terrain

This is a moderate to strenuous adventure. You’ll trek through the jungle (about 45 minutes each way), cross streams, and climb over slick limestone boulders inside the cave. While no technical climbing skills are needed, sturdy shoes and good mobility are essential. This tour is not recommended for guests with limited mobility, balance issues, or recent injuries.

Safety and Risk

The ATM Cave is a protected archaeological site and natural cave system, which means there are no handrails, no lighting, and no paved walkways. All tours are led by trained and licensed local guides who are CPR certified and highly experienced with the cave’s route and challenges.

The cave is safe when approached with caution and respect—but it’s also a raw environment, not a theme park. Visitors are responsible for following the guide’s instructions at all times.

Recommended Age and Group Size

Children must be at least 40 inches tall, and we recommend this tour only for those 12 years and older due to the physical and environmental demands. Group sizes are limited to reduce impact on the cave and maintain a safer, more intimate experience.
