Hydra (Greek: Ύδρα, pronounced [ˈiðra] in modern Greek) 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 ancient times, the island was known as Hydrea (῾Υδρέα, derived from the Greek word for "water"), a reference to the natural springs on the island. There is one main town, known simply as "Hydra port". It consists of a crescent-shaped harbour, centred around a strand of restaurants, shops, markets, and galleries that cater to tourists and locals (Hydriots). Steep stone streets lead up and outward from the harbour area. Most of the local residences and the hostelries on the island are located on these streets. Other small hamlets on the island include Mandraki, Kamini, Vlychos, Palamidas, Episkopi, and Molos.
