Boat and Ferry Travel
In the greater Istanbul area, ferries can be the most efficient (and pleasant) means of getting around. On the Aegean and Mediterranean coasts, boats are used mostly for leisurely sightseeing and yachting.
Şehir Hatları, a subsidiary of Istanbul Metropolitan Municipality, and private companies Dentur Avrasya and Turyol provide regular ferryboat services within Istanbul, while İDO offers boats to Yalova and Bandırma (both in the Marmara region) and to Bursa, as well as a ferry to Istanbul's Princes' Islands. From Bodrum and other Aegean resorts, ferries make frequent runs between Turkey and the Greek islands in the summer.
