Advanced shore-entry cavern with Hells Bells formations.
Cenote Zapote (Hells Bells) is an advanced shore-entry cavern dive near Puerto Morelos with a narrow opening that drops into a broad flooded sinkhole. The draw is the bell-shaped formations that hang in the overhead space, the sharp shift from the shaft into the chamber, and the eerie hydrogen-sulfide layer that marks the lower zone. It is best approached as a guided overhead dive with a deliberate pace and careful buoyancy.
