Actun Tunichil Muknal is a mysterious and beautiful portal to the ancient Maya and their traditions, ceremonies and spirituality. This cave system served as a ceremonial site where the Maya performed sacrifices and other ceremonies as they dealt with extreme and harsh conditions in times of drought.
Explore this lush area surrounded by beautiful jungles, and the cave entrance is traversed by swimming across a crystal clear spring fed pool. Spend 3 hours in the cave after hiking in through the rain forest. Here you will see stunning artifacts, altars and the crystallized skeletons of the sacrificed girl, The Crystal Maiden.

Atm Cave Belize (actun Tunichil Muknal)
Taking a journey into the Maya underworld at Actun Tunichil Muknal (ATM) or the “Cave of the Stone Sepulchre” for one of the most enlightening, epic and unique experiences of your life. Leave the world of the living behind as you venture into the heart of the ATM Cave with your licensed guide. Recently deemed the #1 Sacred Cave destination in the world by National Geographic, the ATM cave is not only beautiful geologically with its crystalline stalactites and stalagmites, but also historically, as is a natural museum of ancient Maya artifacts, as well as a sacred burial place. This is the final resting place of “Crystal Maiden,” an ancient Maya ceremonial victim, as well as the remains of 13 other sacrificed men, women and children. Your professional guides have led government officials, National Geographic, Discovery Channel, The British High Commission and US Embassy officials into the ATM Cave. This sacrificial site is accessed by a 45 minute drive from our office in San Ignacio.
Here we enter the Tapir Mountain Nature Reserve and park our vehicles at the ranger post. From this point on we are on foot, hiking through the jungle for approximately 45 minutes to the entrance of the cave. To access the cave we swim across a small spring- fed pool and wade into the dark underworld of the cave that allows us access the extensive underground maze of tunnels, passageways and chambers, climaxing in the ceremonial chamber housing stoneware, ceramics, the famed crystallized skeleton of the “Crystal Maiden”. We spend approximately 3 hours in the cave at the guidance of our experienced guides. We enter back into the jungle world and hike to our vehicles where we relax and enjoy a homemade picnic lunch with water and soft drinks before driving back to San Ignacio. Difficulty level: Moderate (involved some easy swimming and life jackets are provided for non-swimmers, who will also be escorted by our highly trained guide).

This was one of the best trips we’ve ever done. I can’t describe the feeling of being in the cave exactly how it was left by the Mayans around 900AD, as nothing has been excavated or even touched. Cameras and phones are not allowed which is excellent as it means you listen to and look at everything the guide tells you. They are so knowledgeable. There is some scrambling, climbing and swimming to do through the cave system to reach the dry cave but the guides are with you literally every step of the way, pointing out the best route with a helping hand if needed. Most definitely worth the trip, and the lunch back at the parking lot was delicious

This was amazing! I highly highly recommend it to anyone who likes history, water, or adventure. Definitely doable if you are moderately fit--,does require some scrambling up and down rocks but you take it very slow and your guide tells you exactly where to put your feet. The highlight of our trip to Belize and if you're only going to do one tour in San Ignacio, this should be it!

What an amazing experience! Emil, Britney and Esidoro were outstanding. Emil was not only fun but super knowledgeable and friendly. He took the time to explain a lot of things and made the tour feel unique and different. A must do with an amazing company. We booked other tours with them after such a great experience

I loved this beyond words. Our guide Magdaleno was fantastic. I only have one thing that I think is helpful to share, if you get motion sickness from bus rides at all, then you should know the road to the cave is rough. I hadn’t thought about it at all, and had a hard time. I sat in the front in the way back and was fine but if you get queasy, take something in advance.

Great tour end to end. Cave itself is a one of a kind place and most definitely worth visiting while in Belize. Alex, our guide, was very knowledgable and did an excellent job explaining the background of everything we saw in the cave. He kept a close eye on those in the group that were not the best swimmers and made sure everyone was safe and enjoyed the trip. Highly recommend both the cave and MayaWalk.

This was a well planned, safe, informative and extremely enjoyable tour. All of the guides were very knowledgeable and taught us so much throughout the trip. The tour felt respectful to the culture but also allowed you so close to artefacts and human remains that it was truly an unforgettable experience. Afterwards we felt lucky that we even get to see this cave. Please listen to the guides when they inform you what to pack and what not to do as past visitors have damaged areas of the caves. The tour is not strenuous however I would recommend that participants are fit, moderately flexible (to fit around tight around in the caves) and I would not recommend those that are claustrophobic or afraid of the dark to do this tour. Thank you so much to Maya Walks for leading such a great experience.

Cristian was a great guide! Very informative and answered all of our questions. We spent more time in the cave than other tour operators. The lunch provided by Sadia was also quite tasty. Would highly recommend this tour.
