Explore Tulum’s Cenotes – A Unique Subterranean World The cenotes of the Yucatán Peninsula are gateways to an ancient underground river system formed thousands of years ago. These submerged caves were sacred to the Mayan civilisation, believed to be portals to Xibalbá, the underworld. Today, they offer a one-of-a-kind diving experience, featuring crystal-clear waters, visibility exceeding 50 metres, and breathtaking geological formations. Each cenote has its own character: some have wide openings, allowing sunlight to create mesmerising light beams, while others feature narrow passages adorned with stalactites and stalagmites sculpted over millennia. Additionally, haloclines, where freshwater and saltwater mix, create a surreal visual effect. Diving in Tulum’s cenotes is a journey through time and geology, offering a safe yet thrilling experience for certified divers seeking an extraordinary adventure beyond the ocean.
