For short trips to and from nearby cities and towns, or for excursions to local attractions, you can catch a smaller, no-frills bus which usually hold around 15 passengers. These buses either depart from the main bus station, and/or from a smaller satellite bus station on the side of town nearest the destination.
These bus routes are run by local companies or cooperatives, and the buses usually depart from around 6:00 AM to midnight on an hourly basis or less.
The smaller companies seldom, if ever, have a website where you can book online. To book a seat, you will need to call or go to the bus company office which will be at the local bus station, or at a booth at their main stop in the city or town.You can also just show up, pay the fare, and hop on. They don't usually fill to capacity except during peak hours or on Turkish holidays. But if the next bus is full, you'll be able to get on the one departing after that.
If you're going to a place along the way to their destination, let them know, since you might be charged less.
While the drivers of these buses don't seek out passengers along the way like a dolmuş, they will stop and pick you up if you flag them down.
