Frankly, 3 days is scarcely enough time to explore very much of anything anywhere, let alone Istanbul, the seat of three world empires. Expect only to cover the bare basics of Istanbul, and to leave thoroughly exhausted, with an aching back and calloused feet. But you will also leave culturally enriched and pining for more. This section gives you a rough outline of what you can see, on a load of caffeine, in 1, 2, or 3 days in Istanbul. Consider these itineraries as a suggestion of Istanbul's greatest hits, the top sights you will want to cover regardless of the length of your trip.
