Step into the world of Ottoman sultans, Byzantine emperors and spice merchants on a full-day, small-group Istanbul tour with a sightseeing cruise of the Bosphorus Strait. Trace an all-star route through the Old City, from Hagia Sophia to the Blue Mosque and Hippodrome Square. Pause for a traditional Turkish lunch at a neighborhood restaurant, then immerse yourself in the exotic scents of the Spice Bazaar. Leave the city walls behind for a boat trip along the Bosphorus, and take in views of Istanbul’s palaces, villas and fortifications from the water.
