Zapote

Cenote Zapote is a place that rewrites what you think a cenote can be. This deep, bell-shaped cenote near Puerto Morelos is famous for one extraordinary geological feature: the "bells" — bizarre, bell-shaped speleothems that hang from the ceiling at around 30 meters depth. These formations, found in only a handful of locations worldwide, are believed to have formed during the last ice age when water levels fluctuated and created these uniquely shaped deposits that look like rows of ancient church bells suspended in the water.

The dive at Zapote begins with a descent through a narrow opening in the jungle floor into a vertical shaft that drops away beneath you. As you descend past the halocline and the water temperature drops slightly, the walls of the shaft begin to flare outward, revealing the true scale of the cenote — a massive bell-shaped chamber that extends deep into the earth. At around 30 meters, the famous bells appear: dozens of formations ranging in size from small cones to structures several meters across, all hanging from the ceiling in surreal rows.

The hydrogen sulphide cloud at Zapote typically sits at around 33 meters, creating an additional layer of visual drama. Above the cloud, the bells are illuminated by your dive light in crystal-clear water; below the cloud, darkness and mystery. The combination of the unique formations and the chemical layering makes Zapote one of the most photographically rewarding cenotes for advanced divers.

Because of the depth required to reach the bells, Zapote is classified as an advanced dive. Divers should hold an Advanced Open Water certification at minimum and have experience with deep dives. The narrow entry point also means this cenote can feel more committing than some of the wider, open cenotes. But for those with the skills and nerve, Zapote is an absolutely unforgettable dive — a chance to see geological formations that exist almost nowhere else on Earth.
