The Otogar is on the edge of city and has many major lines that come and go from Ankara and Istanbul all day long. Most of these lines will offer you a free service to the town square. There are also a few busses every day going every direction, to and from Izmir, Antalya, and Trabzon. To come and go from Samsun, the nearest city on the Black Sea coast, there are small Metro minibuses that leave several times a day.
The major sights of the city include the whitewashed Ottoman houses lined by the river and the ancient Pontic rock tombs engraved on the side of the mountain overlooking the city.
