ATM Cave Belize- Actun Tunichil Muknal, Cayo

#1 of 33 in Nature in Belize
Embark on an adventurous hike through ATM Cave Belize- Actun Tunichil Muknal, a cave brimming with Mayan history. Be aware that traversing the cave requires a decent level of fitness, as you'll find yourself climbing, squeezing through tight spaces, and in rare cases swimming to explore the sites. The cave system spreads through about 4.8 km (3 mi) with a river flowing through it for approximately 3.2 km (2 mi). Be on the lookout for large spiders, freshwater crabs, and lots of bats. The highlight for most visitors is the undisturbed skeletal remains and pottery of Mayan origin, such as the "crystal maiden," whose calcified bones give off a crystalized, sparkly appearance.

  • ATM cave is amazing but my bad score goes to guides who step over the line. You can almost see sweating over the artifacts. Also there are careless tourists almost walking over artifacts when I was th...  more »
  • This place is awesome. Since there are so many reviews already, I probably don’t need to elaborate. So just do it! (As long as your comfortable with water.)  more »
  • Actun Tunichil Muknal. The famous ATM Cave tour. This was probably the craziest most haunting thing I’ve ever done. National Geographic proclaimed the ATM Cave the number one sacred cave in the world and many people have traveled to Belize just for this “tour.” It was by far the highlight of our trip, and not for the faint of heart. Expect to be spelunking half-a-mile through a cave, and in and out of tight spaces in the dark for at least a few hours. There are also some sections that you will have to climb a bit to make it to the "cathedral" chamber. Make sure you go with a reputable company, because we witnessed a few other guides in passing that were not near as helpful as ours. Our guide has been leading expeditions into this cave for over 20 years and he was super helpful and told us exactly where to put our hands and feet. Find someone like that for this enter at your own risk tour. It’s definitely a safety first scenario. You’ll want to sign up for the ATM Cave Tour as early as possible so you don’t miss out, and you’ll also want a pair of water shoes. I bought some for $12 US or so in town the day before.
  • This cave is incredible!! We did a tour of the ATM cave and were blown away by the beauty of the cave, the pretty crystal formations inside, the challenging but fun exploration and the amazing Maya artifacts left as they were initially (re)discovered for visitors to experience first hand. We went on this tour with Pacz Tours... Oscar was our guide and he was amazing. Highly recommend this cave tour. This was one of our favorite trips of our vacation in Belize.
