Istanbul sits on two continents and has served as the capital of three empires.What you can do is concentrate on the Sultanahmet historic district, which packs more significant monuments into a small area than almost anywhere on earth, and come away with a genuine understanding of why Istanbul is one of the world's great cities.
Getting In and Out
Istanbul has two airports. Istanbul Airport (IST), the main hub, is 40 to 60 minutes from the centre depending on traffic and transfer method. The new Metro line (M11) has improved this considerably. Sabiha Gökçen Airport (SAW) on the Asian side takes 60 to 90 minutes to the European historic centre. Budget transfer time carefully.
Morning
The Sultanahmet district is where you start. The Blue Mosque (Sultan Ahmed Mosque) is free to enter and genuinely spectacular, but closes to tourists during prayer times. Arrive early to avoid the gap in access around midday.
Directly opposite the Blue Mosque is the Hagia Sophia. Originally a Byzantine cathedral built in 537 AD, later a mosque, then a museum, and now a mosque again, it's one of the most significant buildings in human history. Entry is free but the interior gets very crowded. Come as early as possible.
Between the two mosques, the Hippodrome (now Sultanahmet Square) contains the Obelisk of Theodosius, a 3,500-year-old Egyptian column brought to Constantinople in the 4th century.
Afternoon
The Topkapi Palace and its collections deserve a full morning on their own. If your schedule allows, the Treasury and the Harem are the highlights. Book in advance.
Lunch in the Eminönü area by the waterfront: the simit (sesame bread rings) sold from carts are the quintessential Istanbul street food, and the fish sandwich stalls at the Galata Bridge are a local institution.
After lunch, cross the Galata Bridge on foot to Karaköy and walk up the hill to the Galata Tower. The tower gives another angle on the city, and the Beyoğlu neighbourhood around it, particularly İstiklal Avenue, is modern Istanbul's main commercial and social street.
Evening (if time allows)
A Bosphorus ferry from Eminönü gives you the experience of crossing between Europe and Asia. Even the short public ferry crossing to Kadıköy on the Asian side and back is worth it for the perspective.
Beyoğlu and the streets around Taksim Square are the best options for dinner, with Turkish meyhane (taverna-style restaurants) and raki.
What to Skip
The Grand Bazaar is vast and interesting but extremely tourist-facing. The Egyptian Bazaar (Spice Bazaar) near Eminönü is smaller, more authentic, and easier to navigate in limited time.
The Princes' Islands day trip requires at least four hours. Not for a 24-hour visit.
Istanbul deserves much more than a day. Our Istanbul guide covers how to plan a proper stay across both sides of the Bosphorus.
