Imagine a Caribbean reef thriving as it did 50 years ago. This is Jardines de la Reina, a vast and strictly protected marine park off Cuba's southern coast. Decades of shielding from commercial fishing and development have created an unparalleled underwater sanctuary. Access is severely restricted, with only a handful of permits granted. This exclusivity makes a Cuba liveaboard a rare privilege to witness a perfectly preserved ecosystem, a living example of what the Caribbean once was. Your Cuba diving experience centers on the legendary Gardens of the Queen. Itineraries explore the best dive sites Cuba offers, like the shark-filled channels of Pipín and the dramatic walls of Farallón. Here, encounters with large populations of Caribbean reef sharks and silky sharks are the norm, not a lucky sighting. Divers regularly meet massive Goliath groupers and navigate dense schools of fish. The journey is distinguished by the unique opportunity to snorkel with American crocodiles in the calm mangrove channels, an unforgettable highlight. The primary season runs from November through May, offering the most stable surface conditions. During these months, water temperatures are consistently warm at 26-28°C (79-82°F), making a 3mm or 5mm wetsuit ideal. Underwater visibility is generally excellent, often exceeding 30 meters (100 feet), providing breathtaking views of the vibrant reefs and the impressive megafauna that patrol them. This destination is best suited for experienced divers with a strong appreciation for conservation and remote, expedition-style diving. The pristine conditions are a result of its isolation, and the trip rewards those comfortable with a full week at sea. If your goal is to witness a truly wild, shark-rich environment and experience one of the world's greatest conservation
