The Atlanta Greyhound Bus Station (see map) is right next to the Garnett MARTA station. Garnett is one stop south of Five Points on the north-south rail line. To be honest, it is a little sketchy, especially after dark. So I wouldn’t recommend coming into the city after dark nor leaving very late at night.
You can buy your Greyhound tickets online to save any waiting at the station. Passengers are asked to be there 20 minutes before departure.
