Here's everything you need to know before you start planning a trip to the Actun Tunichil Muknal Cave.
The History of the ATM Cave
The ATM Cave may today be known as a popular tourist attraction and a great place for caving adventures but the Mayas knew it as the "Cave of the Stone Sepulcher". While ancient historical records are spotty, there's plenty of evidence that Actun Tunichil Muknal has been a sacred site for the Maya people practically since their origins.
The Maya first discovered the cave between 300 and 600 AD, but the dark and dangerous environs prevented them from venturing into its deepest realms for quite some time. Somewhere between 700 and 900 AD, the cave had become an important spiritual site for the local peoples. Since what's now modern Belize was once one of the major hubs of the Maya Empire, that makes it one of the critical spiritual sites for one of the most prominent cultures in Mesoamerican history.
Virtual Audio Experience
Elias Cambranes, expert ATM cave guide from K'atun Ahau Tours, takes us on the first of its kind virtual audio experience of the ATM cave.
While we may not have a full account of the importance of this cave to the Mayas, modern archaeologists have been able to piece together a fascinating look at their habits and practices in a relatively short amount of time. The cave wasn't rediscovered until 1989, and archaeological investigations prevented it from being made open to the public until 1998.
The first person to explore the cave in modern times was Dr. Jamie Awe, who conducted research there with his Western Belize Regional Cave Project from 1993 - 2000. While it's since become a treasured destination for the most adrenaline-fueled outdoor adventurers, its relevance to anthropologists and archaeologists can't be understated. European colonialism destroyed many of the records of the Maya civilization, and that makes the ATM Cave something of a rosetta stone towards unlocking the customs and traditions of these mysterious people.
The volume of archaeological discoveries in the ATM is truly stunning. Over 1400 human artifacts have been discovered, all of them dating from 250 to 909 AD. The combination of pottery, tools, weapons, and vessels for water tell a tale of a broad and advanced society, and the scope of the discoveries make it one of the most worthwhile finds in archaeological history.
ATM Cave Tour Price
How much does it cost to visit the ATM cave? Prices vary from $100 USD per person to $365 USD or more per person. These are shared tour prices. Private tours are available at an additional cost. Either way, groups are limited to 8 per guide. The price depends on several factors, especially where you are located in Belize. Most tours depart from San Ignacio. The average shared tour price from San Ignacio is $100 to $125. If you book from anywhere other than San Ignacio, the transportation will factor heavily into the final price you pay. If you have your own transportation, you can book a tour that departs from San Ignacio and coordinate with the tour provider to meet them in San Ignacio or Teakettle village. All ATM tours must be booked and paid in advance. You can compare and book direct at the best prices on Belizing. [

The Crystal Maiden
Many of the stories that can be gleaned from the ATM Cave are rather bleak in nature. It's believed that as part of their sacred rituals, the Mayas used Actun Tunichil Muknal to conduct human sacrifices. Well-preserved human skeletons are just as prodigious in the cave as handmade artifacts are, but the most famous of these finds is the "Crystal Maiden".
Due to the passing of time and the unique climate of the caves themselves, this alleged victim of sacrifice has a glimmering appearance that evokes a sense of the supernatural. The maiden herself was found in a main chamber that was believed to be the heart of this makeshift temple, and the presence of "kill holes" further supports the notion that the skeletons found within were the victims of ritual sacrifice.
Other evidence suggests that the sacrificial practices involved significant acts of ritualized torture as well. A Stelae Chamber that serves as one of the centerpieces of most tours contains stelaes where anthropologists believe that victims were placed bound and then bled for the approval of the gods.
Fourteen intact bodies have been found in the main chamber with half of them being children under the age of five. It's believed that young children were favored sacrifices because their purity made them pleasing to the gods.
But not all of the important discoveries are so gruesome. The famous "Monkey Pot" found within the depths of the cave contains a design that's replicated in only three other discovered artifacts, and it's one of the most treasured indications we have regarding the sort of art and craftsmanship that the Mayas indulged in.
Understanding why this cave was of such sacred importance to the Mayas requires an understanding of their spirituality. In the Maya religion, the gods of agriculture, rain, and fertility were believed to reside in the underworld. It would only seem natural that the ATM Cave, with its seemingly endless pits, would be seen as a potential gateway to the underworld. By making human sacrifices within the cave, they could appeal to these important gods practically at their front door.
Visiting the ATM Cave
The cave itself plunges down to approximately four miles, but due to safety concerns, visitors are only allowed about two-thirds of the way down. Visits to the cave have become a popular tourist activity, and any trip with an approved guide is perfectly safe, but you should take some preparations for your own comfort.
You are not allowed to visit without a licensed guide. There is a daily limit of 125 visitors allowed in the cave.

You should
book your tour early to ensure that you secure your spot for your preferred day. Park rangers collect entry tickets at the gate, but tickets are only sold in San Ignacio town and only to licensed guides. Additionally, your guide must be licensed specifically for the ATM cave. There are only about 25 such licensed guides in the country.
Driving to the Site
The drive to ATM is through the village to Teakettle in Western Belize. Most tour prices are inclusive of transportation, lunch, and entrance fees. Some tour companies may consider a small discount if you provide your own transportation up to the cut-off point in Teakettle. Results may vary, because the tour company will usually still need to send a vehicle, driver, and guide whether you drive with them or not. We don't recommend taking your own transportation.
The drive is approximately 45 minutes from the Teakettle village to the ATM park, through winding dirt roads, citrus orchards, cornfields, and at least one river crossing. If you're thinking of attempting the drive, we recommend a 4 wheel drive vehicle.
*Don't drive to the site thinking you can slip your way into the cave without a guide. There are no guides on site. They also don't sell park tickets on-site, so you won't get past the park rangers at the gates. Tour guides who happen to be there with other visitors will only have tickets and food for their group on that day.
What to Bring/Wear?
Guests should dress as if preparing for a hike, bringing comfortable clothes and sturdy
closed toe shoes. You must also wear
socks. This is mandatory when you're inside the cave, for preservation purposes. After climbing up 'the elevator' you will remove your shoes for the rest of the way.
Most of all, just keep in mind that
you will get wet (soaked) during your visit. You should bring a small backpack with an
extra set of clothes. You'll also want to bring a bottle of sun block able to protect you against the jungle heat and a
water bottle to keep you hydrated throughout the journey. Just make sure it's sealed.
Bring a light snack for the hike. The hike is about 45 minutes from the parking lot. Put your snack in a ziplock back so it doesn't get soaked in the river.
Also bear in mind that
no cameras are allowed within the cave or on the trails. The prohibition of cameras prevents damage to remaining skeletons and artifacts and preserves ATM for future generations.
- Socks (this is MANDATORY)

What to Expect?
The tour starts with a forty-five minute trek through Tapir Mountain Nature Reserve. It is a great way to soak in the majesty of the surrounding jungle. Your guide will provide information about the local flora and fauna, and you may even spot some of the exotic wildlife that calls this area home. There are three river crossings on your hike. The first crossing is at the very start of the hike, across freezing chest-high water pulling yourselves across on a rope. By the time you arrive at the entrance of the cave, you will be soaked.

Your tour through the cave takes about three hours on average. Bringing a dry change of clothes for the deeper voyage is advised but not necessary. There's more swimming and climbing (in the dark) to come. If you suffer from claustrophobia, the ATM tour may not be the right fit for you.
There's a reason why tour guides are required for visits to the cave, and it's not just to preserve the skeletons and artifacts contained within. The cave itself is a labyrinth of interlocking chambers, and one can quickly get lost if they don't have someone to provide them with bearings.
The archaeologists and caretakers of this cave have been reverent in its preservation. All of the everyday artifacts were left as they were to preserve things as they were before modern people arrived, and a knowledgeable tour guide can provide you with a fascinating insight into how these people lived. Any of the certified ATM guides are highly trained to lead tours into this cave.
Is it an easy tour?
This is a physically taxing tour, and the combination of tight corridors and pitch blackness can be a challenge for the less resilient, but it's well worth a journey for anyone who's up to the task. On a scale of 1 to 10, this cave is about a 6 in terms of difficulty due to the long hike and some climbing.
Guests are equipped with headlamps, and reaching the deepest layers of the spiritual cave means venturing through five hundred meters of water. If you can't swim, life jackets are provided. There are only one or two areas where swimming is necessary, including at the very entrance of the cave. The tour is perfectly suitable for swimmers and non-swimmers alike.
While the most commonly cited appeal for these tours is the human artifacts, the natural beauty of the cave is equally as impressive. The stalactites and stalagmites are often meters in height. The fact that it's taken tens of thousands of years for these formations to develop is a true marvel, and it's no wonder that the Mayas saw the caves as a mystical portal directly to the underworld.
The ceremonial chamber where most of the sacrifices were performed and the Crystal Maiden was discovered is the most humbling landmark within the caves, but it's not the only one. The first notable human-occupied chamber that visitors experience is what archaeologists have dubbed "The Cathedral". While the dark rituals were performed another three hours deeper into the cave, the Cathedral served as something of a waiting area. The urns and stoneware were practical in purpose, used by the shamans in preparation for the human sacrifices that would take place later.
Actun Tunichil Muknal has earned its reputation as one of the most stunning natural and anthropological sites around. National Geographic ranked Actun Tunichil Muknal as the number one sacred cave in the world, placing it above breathtaking spiritual caves throughout India, Greece, and China.
