Actun Tunichil Muknal Cave, Belize

Take a look at the cave with Dr. Jaime Awe, the first archeologist to explore it.

Deep in the jungles of Belize, a sacred site has begun attracting tourists that are willing to hike, swim, and climb their way to reach it. The Actun Tunichil Muknal cave, a place of great significance for ancient Maya, was discovered in 1989. After years of research by Belizean archeologist Jaime Awe and his team, the site was opened to the public in 1998. The site is home to dozens of skeletons, including the famous Crystal Maiden. Although the cave now draws much interest from adventurous tourists, it is still not widely seen: a few years ago, photography and video were banned.

In 2017, Awe visited the cave again with National Geographic during filming for the new series One Strange Rock.

“They're portals to the underworld, to where important gods resided," Awe says, highlighting the cave's importance to the Maya civilization and the world. "We also see human sacrifice. Things must have been really difficult for the Maya to be doing this. The Maya certainly contributed to their own demise.”
