Where Europe comes face to face with Asia, we'll explore the fascinating, multilayered city of Istanbul. We'll lose our way in the Grand Bazaar and feast like kings with locals at a fisherman's wharf. We'll follow the fall of the Byzantium and the rise of Islam at the city's ancient wall, Hagia Sophia, Blue Mosque and Topkapi Palace. To escape the city bustle, we'll board a boat on the churning Bosphorus, make friends over backgammon, and try a traditional bath.
