Overview
The Bosphorus is a winding strait about 30 km long that links the Black Sea with the Sea of Marmara and divides Istanbul into a European and an Asian half. Along its shores stand Ottoman palaces, wooden waterfront mansions known as yalıs, fortresses, mosques and fishing villages, and two long suspension bridges cross it at high level. Ships of every kind pass through, from tankers to small fishing boats.
The easiest way to see it is by ferry. Public ferries and tourist cruises run from Eminönü and Kabataş, passing Dolmabahçe Palace, the Ortaköy Mosque, the Bosphorus Bridge and the Rumeli Hisarı fortress, built in 1452 before the conquest of the city. On either shore, walking promenades, fish restaurants and tea gardens make good stops, and the districts of Bebek, Arnavutköy and Kuzguncuk have a village character.

Best time to visit
April to October is the main season, with long, mild days, and the Bosphorus is at its best in spring and autumn. Winter can be cold and wet, though the views are clear and the boats less crowded. Sunset cruises are popular all year.

Getting there
Fly to Istanbul (IST), then take the metro and tram to Eminönü or Kabataş for the ferry. Public ferries run on set routes, and tourist cruises leave at set times. Buses and taxis run along both shores, and ride-hailing services work in most districts.
What to expect
The public ferry is cheap and gives the same views as a tourist cruise, though without commentary. Allow one and a half to two hours for a short cruise, or half a day for a longer trip with stops. The deck can be windy and cold, so bring a layer.
Practical tips
- Use the public ferry for a low-cost trip and a more local feel.
- Sit on the outer deck, and bring a jacket even in summer.
- Combine with a stop for fish or tea on one of the shores.
- Check the timetable and the last return ferry before you go far.
