Cuba

Cuba's diving is a direct consequence of its political history. Decades of restricted access, limited commercial fishing, and minimal dive tourism produced reefs that — in many areas — look like the Caribbean did fifty years ago.

The crown of Cuban diving is Jardines de la Reina (Gardens of the Queen), a 150-km-long archipelago off the south-central coast, reachable only by liveaboard from Júcaro. The reef here is a UNESCO Biosphere Reserve and the dive sites — accumulated over seasons of careful management by the small number of operators permitted to work there — have sharks and groupers in numbers that are now rare almost everywhere else in the Caribbean. Silky sharks at 30 meters. Caribbean reef sharks on every dive. Goliath groupers lurking in canyons. Hawksbill and green turtles in profusion. The water is crystalline.

The Bay of Pigs (Bahía de Cochinos) on the island's south coast offers something Cuba has in unusual abundance: coastal cenotes and cave systems opening directly into the sea. Some of these underwater passages are snorkel-accessible; others require technical diving credentials. The reef at the bay's mouth — the site of the 1961 US-backed invasion — has walls, healthy hard corals, and dive sites that rarely see more than a handful of visitors per week.

The broader Cuban reef system is immense and underexplored. María la Gorda in the far west, Playa Girón in the south, and Santa Lucia in the north all have functioning dive operations and solid marine life.

Logistics for foreign visitors are improving but remain complex. Liveaboard access to Jardines is the clearest path to Cuba's best diving.
