Often hailed as the crown jewel of Cuban diving,Jardines De La Reina is a remote archipelago and marine park located off the southern coast. This protected area is one of the Caribbean's most pristine marine environments, boasting incredibly healthy reefs, dense populations of sharks (including silvertips, silkies, and reef sharks), and large groupers. Access is typically via liveaboard boats, offering a truly immersive and undisturbed diving experience.

Easily accessible from destinations like Cienfuegos and Trinidad de Cuba, the Bay of Pigs offers excellent shore diving opportunities. Sites like Playa Girón and Caleta Buena feature dramatic wall dives, intricate cave systems, and a captivating cenote (a natural pit, or sinkhole, resulting from the collapse of limestone bedrock that exposes groundwater underneath). The clear, calm waters are perfect for divers of all levels, including those seeking to complete their certifications.

Varadero

As Cuba's most famous resort town,Varadero offers convenient diving for tourists.
