Step aboard a cruise in Istanbul for a few hours to see the sights along the coast of the Bosphorus, all the way to the Black Sea. As you travel, sit down for a 2-course lunch accompanied by soft drinks and coffee or tea. You'll get great photo ops of the sights from the water, and stop in the fishing village of Anadolu Kavagi to visit the ancient fortress there. Book ahead to make sure you check this must-do cruise off your list.
