Full description
Combine a hiking and adventure experience with an immersion into Maya history and archeology on this trip to Actun Tunichil Muknal (ATM) Cave from San Pedro. Discover one of the “Top 10 Sacred Caves Around the World,” as ranked by the National Geographic Society, which has also been the subject of documentaries by the National Geographic, Discovery, and History Channels.

Choose between the option of a water taxi or an air transfer between San Pedro and Belize City to begin your adventure. Upon arrival in Belize City, start your 75-minute journey to the ATM cave, located in an area known as the Mountain Tapir Reserve. Drive off-road for a 7-mile (roughly 11-kilometer) trip into the jungle, then take a 45-minute hike to the cave, crossing the river at several points.

Upon arrival at the cave entrance, make your way through 12 feet (3.66 meters) of water by either swimming or being towed across (life jackets are mandatory). On the other side, discover an astonishingly large main chamber full of various types of artifacts, from ceramics and stoneware left by the Maya hundreds of years ago to the remains of skeletons.

The Maya considered ATM a highly sacred location as it encloses the famous “Crystal Maiden”, who was thought to be a sacrifice victim. After decades of weathering and natural processes, the surface of the skeleton appears to be covered with a geological sanded finish, giving the maiden a magical fairy-dust appearance. After exploring the cave, exit the way you came in and journey back to San Pedro.
