Cayo Guillermo, in Jardines del Rey, one of the main cuban destinations, is one of region's smallest keys, barely covering 18 square kilometers, although it is rich in plant species, including mahogany, mastic tree and savin.
Many colonies of flamingos and other migratory birds choose the aforementioned islets to nest in winter, a condition that has been preserved while building a tourist infrastructure that respects the natural environment in the first place.
Jardines del Rey's closeness to a 400-kilometer coral reef, considered the second largest in the world - after the one in Australia, gives a touch of class to the region's tourist offer, with a wide range of diving activities in warm and crystal-clear waters.
Its territory boasts, among its major attractions, five kilometers of beautiful beaches, one of which, El Pilar, honors the yacht of same name that belonged to the famous US novelist Ernest Hemingway. Its dunes can reach up to 16 meters in height.
El Pilar is considered one of the best beaches on the Cuban archipelago, due to its wide sand strip and crystal-clear waters.
Vacationers can enjoy the breathtakingly-beautiful sea bottoms surrounding the islet, which can be compared with a giant aquarium, thanks to the existence of several dive centers.
Cayo Guillermo offers first-class hotels, artificial lakes, swimming pools, entertainment and services in an environment that has barely been altered by human action, guaranteeing an unforgettable stay.
It is separated from mainland by a causeway , famous for its lagoons, where trout fishing and beautiful rural landscapes are the main attractions for tourists.
