Welcome to the gateway of the Mayan Underworld. Actun Tunichil Muknal (cave of the stone sepulchre) is commonly referred to as ATM Cave. Located near San Ignacio, Cayo District, it is one of the most impressive Maya ceremonial caves containing rare bloodletting altars used in sacrifices by Maya royalty, and where calcified skeletons, ceramics, and stoneware have been found. The best known as “The Crystal Maiden”, the intact skeleton of a teenage girl, whose bones have been calcified over the years to a sparkling crystallized appearance.

The hike to the cave entrance through the lush Tapir Mountain Nature Reserve requires visitors to swim to the mouth of the cave and then wade through ankle to chest high water and once inside the magnificent cave, the exploration begins. The tour requires climbing and swimming as well as crawling through small spaces. The cave is extensively decorated with cave formations in the upper passages, a labyrinth of dry chambers which lead to the cathedral-like main hall, a towering chamber 350 meters in length and 50 meters wide and filled with artifacts and sacrificial remains. Visitors remove shoes and explore the cave in socks only, to protect the artifacts on the cave floor. After this, another climb takes you to the stone sepulchre (after which the cave is named) where the Crystal Maiden lies. Photography is now disallowed inside the cave unless special permits are obtained.

This is an extraordinary Belize adventure and a rare opportunity to see ancient Maya ceremonial sites and altars as they were and virtually untouched for centuries. A visit to this site is truly profound and unforgettable. After this memorable adventure, we hike back and sit to enjoy a local lunch before heading back to San Ignacio.

Edward was an amazing guide! We had a small group (6 people) and thoroughly enjoyed the ATM caves and entire experience! This is a must do activity!

it was a great tour. love the cave. it was fun and excited. But we have total 8 people in the group which is the maximal that Belize government allow. it's pretty difficult to enjoy the trip and hear what tour guide's explanation while a big group of tour. not everyone would pass message to the people behind them, so you would not know what tour guide has been talking about such as watch out rock, be careful not touch this/that etc. If let me choice again, I would definitely go with less people group.

Excellent trip! Patrick our guide was amazing. Incredibly knowledgeable and passionate about his job and culture. He’s was also super funny! Great company all around. Lunch was great and Van was comfortable. The site is spectacular. Seeing 1k year old relics and skeletons was an experience my kids and I will never forget.
