Your Guide to Diving in the Cayman Islands

Walls, Reefs and the Caribbean Sea

...Highlights: dolphins, turtles, great macro life/marine diversity, schooling fish & big pelagics...
...Diving environment: healthy reefs, wrecks, walls, caverns, beginner and advanced divers...

Named after the caimans that live here, the Cayman Islands have a storied history of ship-wrecked sailors, pirates and adventurers, a reputation that precedes them. For decades, divers have ranked Cayman Islands diving alongside the best the Caribbean has to offer. 3 islands. 365 dive sites. One clear, warm sea. Whether you want to drift along vertical walls, swim inside a Soviet frigate, or hover over sand flats as stingrays glide past your knees, diving in the Cayman Islands delivers without the hype.

Grand Cayman sees the most divers and is the most varied. Shallow reefs inside North Sound, dramatic drop-offs along North Wall, and turtles galore. Wrecks like the USS Kittiwake sitting upright in 19 metres, easy enough for a snorkeler but interesting enough for a tech diver. To dive in the Caymans is to choose your own adventure: wall, wreck, cavern, or coral garden. The west side shelters sites like Devil's Grotto and Eden Rock, where schools of silversides cloud the caves and tarpon hunt the edges. Seven Mile Beach offers gentle, bath-warm diving suitable for beginners. The east end feels quieter with fewer boats, more space.

A Cayman dive can also mean Little Cayman. This is where the drama lives with dramatic walls and swimthroughs. Bloody Bay Wall drops from 7 metres into the abyss, a sheer vertical face plastered in barrel sponges, gorgonian fans, and hard corals. Randy's Gazebo, Lea Lea's Look, the Great Wall; these are names that matter to experienced divers. And then there is Cayman Brac for wreck diving, home to the MV Captain Keith Tibbetts, a 100 metre Russian frigate and the only diveable Soviet warship in the Western Hemisphere. Goliath groupers live inside the wreck. Eagle rays patrol outside.

The 3 islands are spread apart. Ferries exist, but they eat time. The practical way to sample all 3 without packing and unpacking in hotels is a liveaboard diving cruise. Water temperature sits at 26-30°C year round. Visibility averages 30 metres, often better around Little Cayman and Cayman Brac. Currents run mild. Surface conditions stay calm. Cayman Islands diving works for beginners and intermediates, though deeper walls and wreck penetrations suit advanced divers too. Come for the turtles, the eagle rays, the reef sharks. Stay for the 365th dive site you had not planned on finding.


Dive Site Descriptions

To dive in the Caymans across all 3 islands gives you a complete picture of Caribbean diving. Wrecks, walls, reefs, and macro opportunities all sit within a week's liveaboard route. The variety keeps you coming back. And with 365 named dive sites, you would need more than one trip to see them all.




How to Dive the Cayman Islands

Since the 3 islands are quite far apart, the only way to experience them all without the inconvenience of relocating several times is by liveaboard cruise. The Caymans are a popular spot with a very low number of liveaboard operators, so availability can be an issue. We recommend you book 12 months in advance to avoid being disappointed.



The Cayman Islands Diving Season

The islands are very much a year round diving destination. Sea temperature varies little, from a high of 86F/30°C in August/September to a low of 80F/26.5°C in February. You will need little more (and some prefer less) than a 3 mm full length wetsuit. Due to the very deep surrounding trenches, the visibility is usually excellent and averages 100 ft/30m; it is often even better, especially at Little Cayman and Cayman Brac. Currents are very mild and surface conditions are usually calm.

In the summer months of June to September the air temperature is 86F/30°C; while it hits a low of 79F/26°C in January/February. The rainy season starts in May and peaks in October. Rains are usually short but intense. Humidity is lower from December through March. Hurricane season runs from August to October and there is a 1 in 5 chance of one hitting the islands. For more details on the climate in George Town, Grand Cayman, visit the Weather Atlas website.

For marine life, April through June is the time for prolific fish activity on the reefs, especially juvenile reef fish. The summer months are known for silversides on the shallow sites, and in the early summer you will see more green turtles than at other times of year. September is the month for coral spawning.


Where are the Caymans and How Do I Get There?

The Cayman Islands are a British Overseas Territory south of Cuba and north-east of Honduras. It is believed that Columbus discovered these islands in 1503 on his final journey to the Americas, although they are now best known for their tax haven status (and the excellent scuba diving!).
