The cenote Zapote takes its name from the zapote trees that grow in the area around the cenote and is known to divers as "Hells Bells". The park offers tables to set up equipment, showers, and bathrooms. It also includes two other cenotes for expert divers called Holbox and Kin Ha. The Zapote cenote has an hourglass shape. The surface has a diameter of approximately 30 metres, narrows to 15 and then reopens. And this is where we encounter the main attraction of this dive site, the famous Hell's Bells. Hundreds of biothermal bells adorn the ceiling and walls of the cenote which, combining with the green light due to hydrogen sulphide, take this name. As you may have guessed, this is a deep dive and is only available for expert divers.
