Money-saving tips for Istanbul
- The active mosques (Blue Mosque, Süleymaniye) are free — save museum money for Topkapı and Hagia Sophia.
- Get an Istanbulkart and tap onto trams, ferries, and the metro — the public Bosphorus ferry is a scenic “cruise” for pennies.
- Haggle in the bazaars and eat balık ekmek or döner from stalls — a filling meal for $2–4.
