With over thirty dive sites in the clear and shallow waters around the cay, Cayo Largo is deservedly well known as one of Cuba’s best diving areas. Particularly outstanding are the coral gardens to be found in the shallow waters around the islet, while other highlights include underwater encounters with hawksbill and sea-green turtles. The cay’s dive centre is at the Marina Cayo Largo.
The waters around the cays also make for excellent fishing, and the marina offers high-sea expeditions. A variety of day-long excursions to the surrounding cays are also available, including tiny Cayo Iguana, the nearest cay to Cayo Largo (where the eponymous reptiles can be fed by hand), Cayo Rico and the Cayos Pedrazas, 12km from the western tip of Cayo Largo. Most excursions include snorkelling at one of the surrounding coral gardens, a visit to a “natural swimming pool” where the water is only 1m deep, along with a lobster lunch and an open bar.
