Whether you take the ferry between Europe and Asia or trace a loop up the Bosphorus toward the Black Sea, the must-do Bosphorus cruise gives you a chance to view the city’s best landmarks from the water. The two-hour cruise from Eminönü is recommended to see the Maiden’s Tower, Bosphorus bridges, waterside Ottoman palaces, and wooden multimillion-dollar yalılar (mansions). Take a seat on the deck and enjoy the city sliding past.
Should you take the full Bosphorus cruise ending in Anadolu Kavağı, your main activity while waiting for the return boat will be eating fresh seafood (especially if it's hamsi season) and enjoying the Black Sea views. Do save room for yogurt: Kanlica is known for their tart and thick yogurt, and vendors will sell it on board the boat when you get to the stop. Locals enjoy it with superfine sugar sprinkled on top, or mixed with fruit jam.
