About Black Coral
Black Coral I and II are prominent dive sites within Cuba's Jardines De La Reina marine reserve, renowned for their exceptionally healthy coral ecosystems and diverse marine life. These sites are typically explored as part of a seven-day liveaboard itinerary, showcasing the pristine condition of one of the Caribbean's premier scuba diving destinations. The underwater topography at both locations features a vibrant array of corals, including giant gorgonian fans, table corals, and extensive black coral colonies. Sunlight easily penetrates the clear waters, illuminating these formations and creating a rich, biodiverse habitat. The proximity of vast mangrove forests further enhances the reef's health and provides a natural nursery for many species. Divers can anticipate encounters with numerous reef fish, such as angelfish, parrotfish, and clownfish, which thrive among the colorful corals. Sharks are frequently observed, particularly reef sharks congregating at the drop-offs, while stingrays rest on the sandy bottom. Large schools of jacks and groupers are also common sights, making for dynamic and engaging dives. The Cuban government's restrictions on annual visitor numbers ensure the preserve remains unspoiled and protected. Liveaboard excursions typically allow for multiple dives per day at Black Coral I and II. The optimal conditions, with perfect visibility and thriving marine populations, make these sites suitable for divers of various experience levels, particularly those with good buoyancy control who can appreciate the drift diving opportunities.

Conditions & Currents
Moderate currents can run here, so plan drift entries and stay close to the group. Dive profiles here run between roughly 15 and 40 metres, so plan your gas and no-decompression limits around the deeper part of the site. It is usually briefed as a dive for intermediate divers. The site is reached by liveaboard, so entries are run from the tender or straight off the back deck. Tide, wind and season all shift the picture from day to day, so the crew's briefing on the boat always overrides any general description.
Why dive Black Coral from a liveaboard?
Black Coral is one of Mexico's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
Below are the liveaboards that include Black Coral on their Mexico itineraries.
