Hydra is one of the Saronic Islands of Greece, located in the Aegean Sea between the Saronic Gulf and the Argolic Gulf. It is separated from the Peloponnese by a narrow strip of water. In the ancient times, the island was known as Hydrea, derived from the Greek word for "water", which was a reference to the springs on the island.
It is a very popular island because of its extremely picturesque capital, full of red-tiled houses and stone-paved narrow alleys. It used to be the destination of fashionable artists during the sixties and has kept a highly cosmopolitan character.
Garbage trucks are the only motor vehicles on the island, as cars or motorcycles are not allowed by law. Donkeys, bicycles, and water taxis provide public transportation. The inhabited area, however, is so compact that most people walk everywhere.
Hydra benefits from numerous bays and natural harbours, and has a strong maritime culture.
