Discover the mysterious Cenote underworld with our bi-lingual guides Bohish, who is one of the region’s most famous Cenote explorers and wildlife conservationists. He will safely guide you through a labyrinth of wondrous caves and rivers, while passionately sharing his knowledge about the geological phenomenon that took place millions of years ago. In the interior of the Cenotes, millions of fossilised corals and marine animals have been found, such as prehistoric sharks, whales and even elephants and other prehistoric mammals more than 10,000 years old. The animals that are the easiest to admire without specialised equipment are those who have shells, because when they die, they tend to accumulate and degrade until compacted densely, forming what is known as a calcareous rock. Hiking through the caverns and caves you may discover various fossils and ancient Mayan artefacts while Pako wistfully explains about their origin, and purpose, making its history come alive in your imagination.
