Devil's Throat (Punta Sur)

A near-vertical chimney through the coral structure at the southern tip of Cozumel, the Devil’s Throat drops divers from ~30 m to ~38 m through a tight tunnel into a series of chambers ("the Cathedral") before exiting onto a sheer wall. The combination of depth, overhead, narcosis, and required precision buoyancy makes it Cozumel’s signature advanced dive.
