The International Istanbul Intercity Bus Terminal (Uluslararası Istanbul Otogarı) is 10 km (6 miles) northwest of Sultanahmet Square near the district of Esenler.
With 168 ticket offices and gates, its own Metro station, shops, restaurants, hotel, police station, clinic and mosque, the BüyükOtogar is virtually a town in itself. You can catch a bus to Berlin or Baghdad, though you're more likely to be looking for one to Edirne,Ephesus, Gallipoli or Cappadocia.
You can usually just show up at the Büyük Otogar and catch the next coach to your destination in less than an hour, except at holiday times, when many buses may be fully booked in advance. Here are some major routes and travel times.
Hundreds of companies run thousands of buses, mostly big, comfortable and new, day and night. Dozens of companies connect Istanbul and Ankara, with a bus leaving at least every 15 minutes, 24 hours a day. More on bus travel in Turkey...
