Major European cities such as Frankfurt and Vienna are also well serviced by Turkish bus lines. There are daily train and bus connections between Athens and Istanbul via Thessaloniki. The bus is much faster than the train. You can also travel by bus to Syria, Georgia and Iran, and by train to Armenia. Turkish Maritime Lines runs car ferries from Antalya, Marmaris and Izmir to Venice weekly from May to mid-October.
Private ferries run between Turkey's Aegean coast and the Greek islands.
