Coco Cay is often described as an enormous natural aquarium, and many of its visitors say that it’s hard to find another place in the Caribbean that has so many and such beautiful fish. The cay is linked to the Cuban mainland by a stone causeway, which goes on to also connect it to neighboring Guillermo Cay, another natural paradise. There are four scuba-diving centers and several first-class hotels to guarantee your enjoyment of this natural wonderland noted for the diversity of its land- and seascapes, the clarity of its water, the excellence of its sand and the beauty of its 20 miles (32 kilometers) of coralline formations. Here, diving is a fascinating adventure shared with Stoplight Parrotfish (Scarus guacamaia), Grunts (Haemulon sciurus), Yellowtail Snappers (Ocyurus chrysurus), Queen (Holocanthus ciliaris) and other Angelfish (Pomacanthus arcuatus), anemones and Spiny Lobsters (Panulirus argus). Coco and Guillermo Cays, in the Jardines del Rey (Gardens of the King) Archipelago, off the northern coast of Ciego de Avila Province, are 310 miles (500 kilometers) from Havana and 372 miles (600 kilometers) from Santiago de Cuba. Coco Cay has its own airport.
