Istanbul's sights fall into three clusters: the historic peninsula (Hagia Sophia, the Blue Mosque, Topkapı Palace, the Basilica Cistern, the Grand Bazaar), the Bosphorus line (Dolmabahçe, Ortaköy, a Bosphorus cruise, Beşiktaş-Üsküdar) and the modern centre (İstiklal Avenue, Galata Tower, Karaköy). Each cluster is walkable inside itself, but moving between clusters costs time in traffic — which is why Istanbul tours are usually planned cluster by cluster. Three full days is enough to see the headline sights at a comfortable pace.
Three full days covers the headline sights at a comfortable pace: one for the historic peninsula, one for the Bosphorus line and Dolmabahçe, one for Galata-İstiklal and the Asian side. Two days is possible but tight. With five days or more you can add the Princes' Islands, Şile-Ağva or a day trip to Bursa.

Short Bosphorus cruises run about 1.5-2 hours and take in Dolmabahçe Palace, Ortaköy Mosque, Rumeli Fortress and the waterfront mansions between the two bridges. Full-day cruises continue to Anadolu Kavağı and stop there. Sunset departures give the best light for photographs; in winter the deck is windy, so dress in layers.
Yes, because Hagia Sophia, the Blue Mosque, the Basilica Cistern and Topkapı Palace are within walking distance of each other. Topkapı alone takes 2-3 hours, though, and the Harem needs a separate ticket. Starting early and leaving the Grand Bazaar to the end of the day cuts queuing. Mosque visits pause briefly during prayer times.
Closing days differ by institution: some palaces and museums shut one day a week, and it is not the same day everywhere. Hours also change around public holidays, and many museums close on the first day of the religious holidays. So confirm the current days and hours for the specific sites before fixing your plan — on a guided tour that check is done when the itinerary is built.
The islands are reached by ferry; Kabataş or Bostancı to Büyükada takes roughly 50-90 minutes depending on the vessel. Motor traffic on the islands is restricted, so you get around by electric shuttle, bicycle or on foot. Summer weekend ferries are very crowded — going on a weekday or taking an early sailing makes a large difference. Allow a full day.
Inside the historic peninsula the tram and walking are enough; along the Bosphorus the ferry is often faster than the road. A single İstanbulkart works across all public transport. If you are moving as a group with luggage, or planning more than three stops in a day, travelling with a driver removes the changes and waiting.
Yes. Most of Istanbul's headline sights are indoors — Hagia Sophia, Topkapı, the Cistern, the Grand Bazaar — so a winter itinerary loses little to the season and the queues are markedly shorter. In exchange the days are short and rain is likely, and the deck on a Bosphorus cruise is cold. Waterproof shoes and layers are the only real preparation winter Istanbul needs.
