The overnight buses are one of the wonders of Turkey –they run on time, are clean and well serviced and are comparatively cheap. www.bilet.net/otobus is a good starting point; they also have train information.
Minibuses called dolmuşes run in towns and between villages. Usually they run at set times, starting early in the morning and finishing at about 6 or 7 pm (later in towns).
