The island of Hydra, is a small Greek island located in the waters of the Saronic Gulf in the Aegean Sea, south of Athens. Is separated from the Peloponnese by the narrow Hydra Gulf. Hydra is also a municipality and one of the few provinces in Greece to have two municipalities, including the uninhabited island of Dokos with less than 5 communes.
Tourism-dependent island, the Athenians represent a significant segment of visitors to Hydra. Ferries arrive regularly from Piraeus and the port of Nafplion, which is in the nearby coast of the Peloponnese. Except garbage trucks, vehicles are not allowed on the island, which leaves most of the public transportation donkey island and water taxis. The uninhabited area, however, is so compact that most people walk everywhere.
There is a main town, known simply as Puerto Hydra. Port consists of a crescent, around which is the beach and commercial establishments (restaurants, shops, markets and galleries) all of which cater to tourists and Hydriots. Steep stone streets lead out from the harbor area. Most local residences, in addition to catering establishments are located in these streets.
