Kız Kulesi

İstanbul is a maritime city, so it's appropriate that one of its most distinctive landmarks is on the water. The tower, which has an observation deck, small exhibition space and a restaurant, is open to the public. Purchase your ticket from the booth on the Salacak shoreline, then board one of the small boats that cross to the island every 15 minutes. Unfortunately, the views from the island aren't great, the restaurant's food is unimpressive and the tower itself isn't very interesting inside.
