Cozumel DivingThere are no cenotes to dive on Cozumel. Cenote diving from Cozumel is a mainland day trip of 10 to 13 hours door to door: ferry, road transfer, two guided cavern dives in 24 to 25C fresh water, and almost no marine life.

Marine LifeReef conservation diving in Cozumel runs on enforceable rules, not advice: no gloves or knives, no touching coral, mineral sunscreen only, an authorised guide in the water, and 225 pesos a day. Unstable buoyancy breaks more coral than rule-breaking does.

Courses & TrainingSidemount diving is legitimate in Cozumel but a minority configuration: nearly every boat, crew and rental rack here is built around a back-mounted aluminum 80. It earns its place for gas redundancy on the deep southern walls and for trim.

Cozumel DivingCozumel is a recreational drift destination that happens to have deep water. The deepest published site profile reaches 150 feet, helium is not a shelf item on the island, and only a handful of operators support decompression diving at all.

Dive SafetyIf you lose your dive group in Cozumel, turn a slow 360 while looking up, give it about one minute, then end the dive: ascend, deploy your SMB, safety stop if you can, and wait on the surface. The live boat is already following bubbles.

Cozumel DivingYes, and there are four ways to do it: soft contacts under a standard mask, a mask with bonded corrective lenses, custom-ground lenses to your prescription, or a stick-on gauge reader. Rental masks are never prescription, so sort it before you fly.

Dive SafetyCozumel is safe to dive, with three caveats. The real risks are the current, the depth of the southern sites, and the temptation to dive beyond your training, in that order. Both documented shark bites, in 1993 and 1997, were non-fatal.

Trip PlanningA shared two-tank morning boat is advertised at $90 to $150 per person, but with the park fee, rental gear, a computer, nitrox and tips the same day lands at $160 to $240. That gap is why two Cozumel diving packages rarely compare directly.

Dive CentersCozumel's dive centers mostly sell the same morning boat, so four quieter answers decide your week: divers per guide, which dock you leave from, tank size, and what happens to your deposit when the port closes for wind.

Trip PlanningBring Mexican pesos. Dollars are accepted almost everywhere a diver spends money in Cozumel, but when you pay in dollars for a peso price the shop sets the exchange rate in its own favour, and the 225-peso park fee is cash only anyway.

Trip PlanningThe customary tip in Cozumel is roughly 5 to 15 US dollars per tank per diver, so 10 to 30 dollars for a standard two-tank morning. It goes to the whole boat in cash, handed to the divemaster daily rather than in one lump at the end.
