Your tour begins with a hike through the rainforest of the Tapir Mountain Nature Reserve. Eventually you’ll reach the river that leads to the mouth of the cave. You’ll swim for a distance 15 feet (4.5 m) to the entrance. Once you’re inside the cave you’ll walk, wade, and climb to the main attractions, so be ready for some physical activity.

On your tour you’ll see Maya vessels and artifacts, as well as the remains of sacrifice victims. The most famous of these victims is the Crystal Maiden, a young female whose skeletal remains have fused with the sparkling material that forms the inside of the cave. The skeletons are in a part of the cave known as the Cathedral, which is named for its impressively high ceiling and ornate stalactites.

These artifacts and remains are not behind any type of barriers, so be careful and wear a headlamp instead of carrying a cumbersome flashlight.

According to Maya lore, Actun Tunichil Muknal (known locally as “ATM”) connects the world of the living to Xibalba, the Maya underworld. This cave served as the site of human sacrifice – archeologists have uncovered the remains of 6 children and several adults inside the cave. Historians speculate that the Maya intended these sacrifices to appease the gods of the underworld.
