Hydra, one of the most cosmopolitan Greek islands, is located in the heart of the Argo Saronic Gulf. Is built in the shape of an amphitheater on a slope overlooking the Argosaronic gulf. Traditional stone mansions, narrow cobblestoned streets, and the banning of cars with the use of around 500 donkeys as means of public transportation explain the reason why Hydra preserved its distinctive atmosphere through the passage of time. Right and left from the entrance of the port, there are the Parapets with the Canons, which protected the town. You can stroll the picturesque narrow cobblestone alleys and reach the old Settlement of the town, to the medieval fortress town of Kiafa, and from there to enjoy the view toward the Peloponnese. Hydra is famous for the calmness it offers to the visitors in the day, but also for the intense, cosmopolitan nightlife. So the island each year receives a large number of Greek and foreign visitors. Hydra is the birthplace of five Greek Prime Ministers!
