Start early at Hagia Sophia, ideally around 08:30–09:00, before the Sultanahmet area fills with tour groups. Allow about 1½ hours for the Byzantine galleries, Ottoman additions, and the changing access arrangements around prayer times; visitor routes, entrance rules, and ticket requirements can change, so check the official information shortly before you go. From there, walk a few minutes across the square to the Blue Mosque. Plan roughly an hour, but keep your timing flexible because the interior closes to visitors during prayers. Shoulders and knees need to be covered, and women should bring or borrow a head covering; remove shoes at the entrance.
Continue to Caferağa Medresesi, a peaceful former Ottoman school tucked just off the main tourist route. Its courtyard workshops and small craft spaces make a pleasant 45-minute pause—have tea if a local atelier is serving it, and browse without expecting a formal museum visit. For lunch, stay around Sultanahmet rather than crossing town: Matbah Ottoman Palace Cuisine on Caferiye Street is a reliable choice for Ottoman-style dishes, while Sultanahmet Köftecisi is quicker and more casual. Allow ₺400–800 per person for lunch, depending on drinks and shared plates.
Walk north through Beyazıt to the Grand Bazaar, roughly 15–20 minutes from the medrese area, or take the T1 tram one stop from Sultanahmet to Beyazıt–Kapalıçarşı if your feet need a break. Spend about two hours wandering its covered lanes of jewelry, textiles, leather, ceramics, and antiques; compare prices in several shops, ask whether a card surcharge applies, and avoid buying the first version of anything you like. The bazaar generally closes in the early evening and is closed on Sundays, so Friday is a good day for this stop. Finish with dinner around the Şehzade Cafer Ağa Medrese area restaurants near Sultanahmet, allowing 1½ hours and approximately ₺700–1,300 per person. Old Ottoman Cafe & Restaurant is convenient for traditional dishes and a quieter meal; reserve or arrive early if you want a table with a view, and use İstanbulkart on the T1 if you decide not to walk back.
After arriving in Kadıköy, head straight into Kadıköy Market for a leisurely two-hour wander. Start around 09:30, when the produce stalls, fishmongers, bakeries, and spice shops are lively but not yet crowded. Browse the lanes around Güneşli Bahçe Sokak and Tellalzade Sokak, looking for regional cheeses, olives, dried fruit, and simit; stall hours vary, but most food businesses are active from roughly 08:00. Keep small cash handy, although many established shops accept cards. This is a good place to pick up picnic snacks, but avoid filling up before lunch.
For lunch, walk a few minutes to Çiya Sofrası, ideally arriving around 12:00–12:30 to avoid the busiest period. The menu changes frequently and focuses on lesser-known home cooking from across Türkiye—order several small dishes to share rather than committing to one large plate. Budget about ₺700–1,200 per person, depending on what you choose; allow 1½ hours, since the meal is meant to be unhurried. From there, continue west on foot into Yeldeğirmeni, roughly 15 minutes away.
Spend the next 1½ hours exploring Yeldeğirmeni at street level: look for murals, early twentieth-century apartment façades, and the independent cafés tucked along Karadut Sokak and Duatepe Sokak. It is a neighborhood for wandering rather than ticking off monuments, so leave room for a coffee stop and the occasional detour. Then walk or take a short local bus ride toward Moda Park and the Moda shoreline, allowing about 25–30 minutes depending on your route. Follow the waterfront toward Moda Pier for an easy final stroll, with tea at a café overlooking the Sea of Marmara; sunset in late November is early, around 17:45, so begin this leg by approximately 15:30–16:00.
Return from Kadıköy by ferry to Karaköy or Eminönü, checking the Şehir Hatları timetable before leaving the shoreline. The crossing usually takes around 30–45 minutes including boarding, and an İstanbulkart is the simplest payment method; allow extra time after dark for queues and less frequent sailings. If the weather turns rough, use Marmaray from Ayrılık Çeşmesi toward Sirkeci instead.
Start from Kadıköy early enough to reach Feriköy Antika Pazarı around 09:30–10:00. Take the ferry to Karaköy, then use the F1/Tünel connection and metro or a short taxi ride toward Şişli, allowing roughly 45–60 minutes door to door; the market is not a sensible walk from the ferry terminal. Confirm that the Sunday market is operating before setting out, as schedules can change. Give yourselves about two hours to browse the covered stalls and surrounding lanes for old ceramics, brassware, books, posters, jewelry, and small Ottoman-era household objects—cash and bargaining are useful, though prices are usually more flexible near closing.
From Feriköy, walk or take a short local bus/taxi to Bomontiada, the restored Bomonti brewery complex, for a slower late-morning break. The courtyard and industrial buildings are worth seeing even if you do not linger over lunch; allow about 1½ hours and budget approximately ₺500–1,000 per person for a casual meal and drinks. On a Sunday, confirm the individual restaurant’s opening time rather than assuming the whole complex operates on one schedule.
After lunch, take public transport from Bomontiada toward Karaköy—the metro and a short walk are generally more predictable than crossing central Şişli by taxi—and spend around two hours at Istanbul Modern. Its waterfront galleries are a good change of pace after the market, with strong contemporary Turkish art and generous views across the Bosphorus. Check Sunday hours and reserve timed admission if offered; leave room for security and ticket queues. From the museum, walk uphill through Galataport and the lower Galata streets to Galata Tower, allowing about an hour including the likely entry line. Advance tickets are sensible, particularly if you want sunset views, but do not let a long queue compress the rest of the evening.
Continue uphill to İstiklal Caddesi and Tünel, where the atmosphere is liveliest after dark. Rather than walking the avenue in one push, pause in the side streets around Asmalımescit for Turkish coffee, baklava, or a slice of cake, then finish at Tünel Square. The complete day is ambitious, so if the tower queue is excessive, enjoy the exterior and nearby Galata streets instead; the historic tram, shopfronts, churches, arcades, and evening foot traffic provide plenty to see without another fixed admission.
