Kos Island, Greece.
By air: Kos has an international airport in the centre of the island at a distance of 23 km from Kos Town, with twice daily connections from Athens by both Olympic Air and Aegean Airlines, and charter arrivals from many destinations in Northern Europe. There are also local (Olympic)flights three times weekly to Astypalaia, Leros and Rhodes.
By boat: There are daily services by catamaran (Dodecanese Express), and four times weekly by car ferry (F/B Nisos Kalymnos), plying the route between Rhodes, Kos, Kalymnos, Leros, Patmos (& Samos – ferry only): to Piraeus and Rhodes, Blue Star Ferries run four times weekly ferries, and GA Ferries (who include Nisyros, Tilos and Symi en route) three times weekly. The faster Flying Dolphin services link Kos also with the smaller Dodecanese Islands between Samos in the north and Rhodes in the south, and run daily in summer. From Kardamaina on the southeast coast there is a daily connection with Nisyros throughout the year, weather permitting.
