Skiathos is a small Greek island in the northwest Aegean Sea. Skiathos is the westernmost island in the Northern Sporades group, east of the Pelion peninsula in Magnesia on the mainland, and west of the island of Skopelos. The coastline is indented with inlets, capes and peninsulas. The southeast and southwest parts have gentler slopes and that is where most settlements are located. The terrain is more rugged on the north coast, with the highest peak at 433 m on mount Karafiltzanaka. The main town is Skiathos, in the eastern part of the island. Other main settlements are Kalyvia, Troullos, Χanemos, Koukounaries, and Achladias.
