Ios (Greek: Ίος, locally Νιός - Nios) is a Greek island in the Cyclades group in the Aegean Sea. Ios is a hilly island with cliffs down to the sea on most sides, situated halfway between Naxos and Santorini. The Port of Ios is at the head of the Ormos harbor in the northwest. From there the bus or a 15-minute walk up the steep donkey path takes you to the village, known as Chora. Chora is a white and very picturesque cycladic village, full of stairs and narrow paths, that makes it inaccessible for cars of any kind.
