Those who visit the island can encounter numberless attractions related to nautical sports developed in a great deal of facilities set in the vast sea zones of the island. Most of the hotel infrastructure exploited in Cuba is located in beach areas. That is why a parallel set of services related to the sea have been developed so that the tourists enjoy the charms offered by the quiet, limpid, and warm tropical waters of the Caribbean Sea. Companies that offer nautical sport services, like MARLIN, PUERTOSOL, GAVIOTA, and CUBAMAR, count on important facilities with the necessary means for the practice of nautical or beach sports such as: excursions, littoral trekking, sport fishing, aqua bike riding, windsurfing, catamaran riding, kayak, parasailing, snorkeling or diving, and many other attractive activities like night-time diving or underwater photography. The tourist residential area of Hemingway Marina is located in 5th Avenue and 248th Street in the municipality of Playa, Havana City; the Puertosol Marina is located in Via Blanca, Varadero, Matanzas. The International Diving Center "El Colony" also possesses a magnificent marina and is located in the 41st Km of the Siguanea road, in the Isle of Youth. Some keys that have been adapted to cope with a moderate tourist exploitation offer also nautical services in their marinas, where you can arrive directly with your own yacht. These are: Marina Cayo Coco-Cayo Guillermo, situated in Cayo Guillermo, Jardines del Rey archipelago, Ciego de Avila province. Cuban coral reefs, the most preserved in all the Caribbean area, offer exquisite sites for snorkeling and diving practices. The International Diving Center "El Colony", in the Isle of Youth, is one of the most known in the world. "Skark's friends", located in the beach of Santa Lucia, Camaguey, is another of the most attractive sites for diving. Just five miles away from Varadero's Marina Gaviota (located in 21st Km of Las Morlas Road, in the Hicacos Peninsula), the marine park "Cayo Piedras" offers the visitor a silent world of color and the unique adventure of diving to sunken ships that still preserve their original weapons. We advice not to miss this chance of getting close to this Caribbean country where friendship and fraternity are everlasting traits of the Cuban traditions since 1492.
