How many days do you need in Istanbul?
Four days lets Istanbul's two continents unfold. The historic Sultanahmet peninsula alone fills two days — Hagia Sophia, the Blue Mosque, Topkapi Palace and its Harem, the underground Basilica Cistern, and the labyrinth of the Grand Bazaar. A third day crosses to the Spice Bazaar and a Bosphorus cruise past Ottoman palaces and fortresses. The fourth explores the modern side — Beyoğlu, İstiklal Avenue, and the food markets of Kadıköy on the Asian shore. A fifth day rewards a Princes' Islands escape.
