Best for advanced divers, 15-40m, shore entry.
The Pit is a collapsed cenote near Akumal that offers a deep cavern diving experience. The site features a vertical profile, dropping from a cavern ceiling at 15 metres to a basin floor at 40 metres. Divers encounter a distinct thermocline between 15 and 20 metres where fresh and saltwater layers meet, alongside a hydrogen sulphide layer that requires careful buoyancy control to maintain visibility. Due to the overhead environment and significant depths, this site is strictly for advanced divers. Shore entry is straightforward, and the site provides parking, toilets, showers, and changing rooms for visitor convenience.
