Fringed by the finest beaches in the Dodecanese, dwarfed beneath mighty crags, and blessed with lush valleys, Kos is an island of endless treasures. Visitors soon become blasé at sidestepping the millennia-old Corinthian columns that poke through the rampant wildflowers – even in Kos Town, the lively capital, ancient Greek ruins are scattered everywhere you turn, and a mighty medieval castle still watches over the harbour. Visitors to Kos naturally tend to focus their attention on its beaches. In addition to those around Kos Town, there are three main resort areas. Kardamena, on the south coast, is very much dominated by package tourism, but Mastihari, on the north coast, and Kamari, in the far southwest, are more appealing. Away from the resorts, the island retains considerable wilderness, with the rugged Dikeos mountains soaring to almost 850m just a few kilometres west of Kos Town. Kos or Cos (/kɒs/; Greek: Κως [kos]) is a Greek island, part of the Dodecanese island chain in the southeastern Aegean Sea, off the Anatolian coast of Turkey. Kos is the third largest island of the Dodecanese by area, after Rhodes and Karpathos; it has a population of 33,388 (2011 census), making it the second most populous of the Dodecanese, after Rhodes. The island measures 40 by 8 kilometres (25 by 5 miles), and is 4 km (2 miles) from the coast of the ancient region of Caria in Turkey. Administratively, Kos constitutes a municipality within the Kos regional unit, which is part of the South Aegean region. The principal town of the island and seat of the municipality is Kos town.
