The ATM Cave Complete Guide: Everything You Need to Know

Hidden in the jungle near San Ignacio lies one of Belize’s most extraordinary treasures: the ATM Cave, short for Actun Tunichil Muknal, the “Cave of the Stone Sepulcher.”

This is not just a cave. It is a sacred Maya site — a place of rituals, offerings, and mystery. Inside, you’ll find pottery, tools, altars, and even human remains, including the famous Crystal Maiden, whose bones shimmer in calcite.

Today, the ATM Cave is both an adventure and a museum, and visiting it is one of the most unforgettable experiences in Belize.

This guide will cover everything you need to know before visiting — from safety rules and packing tips to history and what you’ll see inside.

📍 Where Is ATM Cave?

The ATM Cave is located in the Tapir Mountain Nature Reserve, about 45 minutes from San Ignacio by road, followed by a 45-minute jungle hike with three river crossings.

Most tours begin in San Ignacio, the adventure hub of western Belize. Travelers coming from Belize City, Placencia, Hopkins, or the islands usually stay overnight in San Ignacio to make the timing easier.

🕑 How Long Does the Tour Take?

  • Total time: About 7–8 hours round trip from San Ignacio
  • Breakdown:
    * 45-minute jungle hike to the cave
    * 3–4 hours inside the cave (swimming, climbing, exploring)
    * 45-minute hike back
    * Lunch included after the hike

It’s a full-day adventure — plan for an early start and a late afternoon return.

💪 Difficulty Level: Is the ATM Cave Hard?

The ATM Cave is considered moderate to difficult.

  • You must swim 15–20 feet at the entrance (life vests provided if needed).
  • Inside, you’ll wade through chest-deep water, climb rocks, and crawl through narrow passages.
  • At the end, you’ll remove shoes and walk in socks to protect artifacts.

💡 Recommended for: Active travelers, ages 12+. Children under 40 inches tall cannot enter.

🛡️ Safety and Regulations

Because the ATM Cave is sacred and fragile, it has strict rules:

  • Small groups only: Maximum 6 people per guide (law reduced from 8 for safety).
  • Daily safety checks: The Belize Institute of Archaeology announces at 7 AM if the cave is open. Heavy rains may close it.
  • No cameras: To prevent damage — past accidents broke artifacts.
  • Guides required: No independent entry allowed.

👉 With licensed, CPR-certified guides, Pacz Tours has safely led thousands into the cave for over 28 years.

🎒 What to Pack for the ATM Cave

Bring only what you need — keep it light:

  • Quick-dry clothing (avoid jeans)
  • Swimwear (you’ll start by swimming into the cave)
  • Socks (mandatory for the artifact chamber)
  • Sturdy water shoes or sneakers (no flip-flops)
  • Change of dry clothes and small towel (kept in the van)
  • Refillable water bottle

💡 Pacz Tours provides helmets, headlamps, and life vests.

🌧️ Best Time of Year to Visit

  • Dry season (Nov–May): Best conditions, lower water levels, smoother road access.
  • Rainy season (Jun–Oct): Lusher scenery and fewer crowds, but higher risk of cave closures.

If you have a flexible itinerary, plan your ATM tour early in your trip. That way, if rain closes the cave, you can reschedule for the next day.

🪶 What You’ll See Inside

The ATM Cave is a living time capsule of Maya civilization:

  • Ceremonial Pottery – Many with “kill holes” drilled to release their spirit.
  • Stone Tools & Altars – Offerings made to the gods of Xibalba (the Maya underworld).
  • Human Remains – More than 14 skeletons, including adults and children.
  • The Crystal Maiden – The most famous figure, fully calcified so her bones glitter in the light.
  • Cave Formations – Massive stalactites, glittering mineral walls, and underground chambers.

Every step tells a story — of a people seeking balance through ritual.
