Always in motion, Turkey’s largest city has a way of thrusting visitors into the action, or at least making them stop to admire the spectacle. From afternoon bathers to fishermen pulling their catch to the bridge, to the flurry of boats on the Bosphorus, or the colorful commotion of the Grand Bazaar, the experience of Istanbul is bigger and better than running through a quick list of sights. Make time to walk the waterfront and steeper streets, and to explore vibrant neighborhoods like Karaköy and Beşiktaş. No matter where you wander, the great metropolis delivers for all fives senses.
