Full description
Your tour will begin as you depart San Ignacio at 8:00AM, before heading to your hike starting point. You will make your first river crossing before hiking for 45 minutes to the cave entrance, where you will listen to some safety tips and learn how to use your equipment. You will then make your way into the cave, swimming and then walking through the main water passage until you reach the boulder and head to the dry chamber. To enter the chamber, you will be required to slip off your shoes in order to protect the cave.

Most of the cave's artifacts have been calcified into the ground, unmoved even by archaeologists, this is a living museum. You will hear your guides talk about the rituals and ceremonies, bloodletting offerings, food offerings and human offerings. The cave contains a total of 15 human remains, five of them still visible, which have been uncovered by archaeologists.

To access the last chamber, you will climb up a ladder to see a full skeletal remains before exiting the cave in the same way you came in. You will hike back to the parking lot before replenishing yourself with lunch and returning to San Ignacio.
