Cozumel DivingScuba diving in Cozumel with kids works if you plan around three things: an operator that has genuinely taught children, a sheltered mid-island reef rather than a famous southern wall, and a schedule that assumes the youngest finishes first.

Dive SitesPADI Wreck Diver is four open water dives across at least two days, from age 15, with penetration limited to the wreck's light zone on a continuous guideline. Cozumel has exactly one wreck, so all four dives happen on the same hull.

Cozumel DivingPADI Deep Diver certifies you to 40 metres over four training dives across at least two days, from age 15. In Cozumel it opens Devil's Throat, Punta Sur, Maracaibo and Colombia Deep, where the no-deco clock at 130 feet allows roughly ten minutes.

Courses & TrainingThree Cozumel specialty dive courses earn their place on a week-long trip: Peak Performance Buoyancy, Enriched Air Nitrox, and Deep Diver if the southern walls are why you came. Most of the rest are better taken at home, or skipped for more diving.

Gear & EquipmentA brand-new mask fogs because of a silicone film left on the glass at the factory, and no defogger will stick until you scrub it off with a gritty non-gel toothpaste. After that, coat the dry lens, swirl out the excess, and stop touching it.

Cozumel DivingMost diving couples are mismatched somehow, and every version is solvable. A non-diver rides the same boat for $55 to $85, Discover Scuba puts you both under the same morning, and a private guide at $85 to $110 a day fixes an experience gap.

Dive SitesSharks at Cozumel dive sites are almost always nurse sharks, lying motionless under a coral ledge and ignoring you entirely. The island's documented bite record is two incidents, both in the 1990s, across hundreds of thousands of dives.

Dive SitesYou do not dive alone in Cozumel even when you arrive alone: every boat dive is guided, and a diver without a partner is assigned one or kept beside the guide. The real solo penalty is the hotel room, which is priced per room, not per diver.
