Hop On & Hop Off Bosphorus Tour
This is an excellent way to visit some of the imperial palaces on the Bosphorus: six daily departures make a loop cruise starting from Kabataş, stopping at Beşiktaş, Emirgan, Küçüksu Kasrı, and Beylerbeyi Palace, returning to Kabataş. The loop cruise takes 1-3/4 hours, but you can hop off the boat at any stop, then hop on the next boat which arrives an hour (or two, or three) later. Obviously, it's a good idea to start your cruising with one of the earliest boats—they begin at 11:45 am. If you join the tour at one of the intermediate stops (Emirgan, Küçüksu Kasrı, or Beylerbeyi Palace), it's half-price.
Full Bosphorus Tour
The daily Full Bosphorus Tour round-trip cruise is similar to the Şehir Hatları traditional ferryboat cruise in that it takes about 5-1/2 hours, with a 3-hour stop at Anadolu Kavağı, giving you time to walk up to the Yoros Kalesi fortress, and to have a seafood lunch if you wish. The Dentur Avrasya Bosphorus Cruise departs Kabataş dock at 11:15 am, Beşiktaş dock a 11:30 am and, for the return trip, from Anadolu Kavağı at 15:30 (3:30 pm).
This is Dentur Avrasya's most active route, with boats departing Beşiktaş and Üsküdar continuously every day from about 06:00 am until 01:15 am.
Dentur Avrasya ferries operate continuously between these two docks from about 06:10 am to 01:00 am.
Dentur Avrasya operates about six ferries daily from beşiktaş via Kabataş to Heybeliada and Büyükada in the Princes Islands. The voyage between Beşiktaş and Büyükada takes 90 minutes.
This is a weekday-only commuter service, with one voyage departing Bebek at breakfast time, and one voyage departing Eminönü in early evening.
