Customize your sightseeing itinerary in Istanbul with a hop-on hop-off boat tour on the Bosphorous River. Your pass is valid for a full day, giving you time to disembark and see more of Istanbul. The cruise passes iconic landmarks including Topkapi Palace, Galata Tower, Dolmabahçe Palace, Hagia Sophia and the Golden Horn. Hop off to see the Rahmi Koc Museum or Miniatürk, and ride the funicular at Eyüp. Check out the fish market at Beşiktaş or remain on board for the full trip, which takes about two hours.
