Grand Cayman
Grand Cayman built its reputation on convenience without compromise: hundreds of moored sites ring the island, walls plunge within sight of Seven Mile Beach, the Kittiwake wreck sits in bright shallow water, and Stingray City puts southern stingrays on your shoulder in waist-to-chest-deep sand. Strict Department of Environment rules, clear water, and polished operators make it the Caribbean's most frictionless wall-diving base.
Why dive here
Three distinct coasts share one small island. The West Wall, minutes from Seven Mile Beach, is the everyday marvel — canyons, chimneys, and orange elephant-ear sponges from about 15 m over the drop. The North Wall is wilder, a sheer face on the edge of a 2,000 m trench where eagle rays and reef sharks patrol sites like Babylon. In between lies North Sound's famous anomaly: Stingray City, where southern stingrays conditioned by decades of fishermen's scraps glide onto divers' hands in a few meters of water. The Kittiwake, a former US Navy submarine-rescue vessel scuttled in 2011, lies within snorkel sight of the surface and opens generously for guided passes. Shore divers get their own classic at Eden Rock and Devil's Grotto, where tarpon hang in cathedral swim-throughs off George Town. Mooring discipline, marine-park zones, and no-glove, no-touch culture keep the reef in shape despite the traffic.
Month by month
December through May is the dry, settled season. Summer stays diveable with warm, calm mornings; September and October carry the highest hurricane risk. Winter northwest swells occasionally shift boats from the West Wall to the sheltered south.

Getting there & staying
Getting there: Nonstop flights arrive from many North American and UK gateways. Dive operators pick up along Seven Mile Beach and George Town; North Side and East End resorts serve the far walls.
Where to stay: Seven Mile Beach puts the West Wall fleet at your door; East End and North Side lodges trade nightlife for empty sites and the best walls.
Costs: Pricier than most of the Caribbean, in line with the island's cost of living; packages, shore diving, and off-peak months soften the bill.
Between dives: Seven Mile Beach, the Camana Bay waterfront, the turtle conservation center, Crystal Caves, and some of the Caribbean's best restaurants.
Safety & practicalities
Hazards: Boat traffic over the popular shallows, winter swell on the west and north coasts, and the temptation of very deep water — the walls keep going long after your plan should stop.
Set a hard depth limit before every wall dive and hold it; the visibility makes 40 m look like 15. At Stingray City keep feet off the sand, shuffle rather than step, and never lift or chase the animals.
Nearest recompression: A hyperbaric chamber operates on Grand Cayman; availability changes — emergencies route through EMS, your operator, and DAN.
