This dive site, Agua Negra, offers a specialized blackwater diving experience off the coast of Cozumel Island. Blackwater diving is a unique night-time activity where divers descend into the open ocean, often far from the reef, to observe the vertical migration of marine organisms. The dive takes place 3-4 miles off the coast over the MesoAmerican Barrier Reef System, creating a surreal environment akin to floating in space. It's a relatively new and niche offering in Cozumel, focusing on observing creatures typically found in the deep ocean as they migrate upwards at night.
The primary draw of Agua Negra is the incredible diversity of marine life in their larval and juvenile stages. Divers can expect to encounter an array of juvenile crustaceans, mollusks, and gastropods, many of which are rarely seen in their early forms. Additionally, there is the exciting possibility of spotting juvenile marlins and sailfish, offering a glimpse into the early lives of these magnificent pelagic predators.
The best time to visit for blackwater diving is typically at night, as this is when the vertical migration of these creatures occurs. Divers should be comfortable with night diving and open ocean conditions. This experience is highly recommended for macro photographers and those seeking truly unique encounters with marine life not found on typical reef dives. Given the open ocean environment, strong currents can sometimes be a factor, and divers should maintain excellent buoyancy control.
