Take a gentle walk in Gülhane Park to enjoy shaded paths, fountains and views towards the Bosphorus — a calm, accessible introduction to the Old City; parks are usually open until late.
Admire the illuminated facades and exterior courtyards of Hagia Sophia and the Blue Mosque — note interiors often close earlier (Hagia Sophia typically 09:00–19:00), so this evening visit is ideal for photos and atmosphere.
Enjoy a relaxed seafood dinner in a historic setting with excellent mezes and a calm atmosphere; the restaurant stays open for evening service but book ahead in high season.
Explore the historic Grand Bazaar’s labyrinth of shops selling carpets, ceramics, jewellery and souvenirs—best to go in the morning before it gets very crowded.
