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.

We had an amazing tour w Jeremy and Edward. Edward was so knowledgeable about every part of the tour. He gave knowledge about the jungle surroundings on the way to the cave such as medicinal plants and the insects. We ate termites for the first time! Once in the cave he was very attentive to safety and the where we where. His knowledge was the best! We will definitely get ahold of him again for a camping trip! Jeremy thank you for the ride and the awesome lunch and rum punch!

Everyone from our driver to the guides, was fantastic. They were kind, patient, interactive, and very safe. My husband (54), son (14 y.o), and myself (40) had a great time. It was physically taxing, so please take care to bring good shoes, a towel, and dry clothes to change into after your adventure.

What an adventure! We loved the nature and cultural aspects of the tour. It was fun crossing the rivers and squeezing into crevices in the cave. The Mayan artifacts and sacrificial ruins were surreal. So much more interesting seeing these pieces of history where they existed instead of in a museum. We were exhausted at the end of the day but it was so worth it. Five star rating from me and my two teenage kids. Highly recommend for those that are active and adventurous. The only room for improvement was the van was very noisy and rattling because of some missing screws on the interior coverings.
