First time in Istanbul? What to know before you go

These are the stops that decide whether a first trip works. Do the big three (Hagia Sophia, Topkapı, Basilica Cistern) on separate mornings, not in one day, and keep one afternoon free for the ferries.

Prices below are 2026 estimates in lira; state museums have raised entry sharply in recent years, so treat the figures as a band and check the official ticket page before you go.

Istanbul splits into three useful zones for a first visit. The historic peninsula (Sultanahmet, Eminönü, Beyazıt) holds Hagia Sophia, Topkapı, the cistern and both bazaars, all within walking distance of each other. Across the Golden Horn, Beyoğlu (Galata, İstiklal, Taksim) is where you eat and go out at night. Across the Bosphorus, Kadıköy and Üsküdar are the Asian side, reached by ferry in about 20 minutes from Eminönü or Karaköy.

The tram T1 links Sultanahmet, Eminönü, Karaköy and Beyazıt; the M2 metro runs from Yenikapı through Taksim to the north. Ferries are the fastest and cheapest way to feel the city's geography. Coordinates below are approximate.

Buy an İstanbulkart at a machine or kiosk on arrival; it works on the metro, tram, bus, funicular and ferries, and one card can be topped up for several people. Single paper tickets are limited, so the card is the practical option.

Carry lira in small notes for markets, simit carts and small cafés; cards are accepted almost everywhere else. Taxis are metered but agree the route or use a ride-hailing app where available. Istanbul is a big, generally safe city, but watch for the common scams around Sultanahmet and Taksim — see the safety page.

Dress modestly for mosques: shoulders and knees covered, and women should carry a scarf for their head. Shoes come off at the door. Friday midday is busy with prayer, so plan mosque visits around it.

Food: eat breakfast like a local (cheese, olives, eggs, tea), try a balık ekmek by the water, and book one proper dinner in Beyoğlu. Tap water is not for drinking; bottled water is cheap.

April to June and September to November give mild temperatures and manageable crowds. July and August are hot and packed, with higher hotel prices; December to February is cold, often wet, and quieter, which suits museum-heavy trips.

Two Islamic holidays, Ramazan Bayramı and Kurban Bayramı, move each year and bring domestic travel, closed shops and full hotels; check the dates before booking. Winter occasionally brings snow that disrupts ferries and flights.
