Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Cenote Zapote (Hells Bells) offers some of Cozumel's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Cenote Zapote, often called "Hell's Bells," is a distinctly different dive from the open ocean. You’re descending into a cavern where the main event is the incredibly weird, bell-shaped speleothems hanging down from the ceiling. They're formed when minerals precipitate around water droplets, creating these alien, flared structures unlike anything you'll see elsewhere. It's a dark, atmospheric dive, perfect for experienced cavern divers who appreciate geological oddities over schooling fish. We'd suggest a good dive light for exploring the intricate details of those bells.
Safety Notes
