Even though the station is located in the city of Dunwoody, it also serves commuters from surrounding north DeKalb and Fulton counties. The Sandy Springscity limit is just 300 meters/1,000 feet west at the county line. It is the only North Line station in DeKalb, as the line (which otherwise runs in Fulton, just west of the due north/south county line) swings east for this station.
Dunwoody has 1,048 daily and long term parking spaces available for MARTA users which are located in two parking decks. Daily parking (less than 24 hours) is free; long term parking is charged at US$5 per day, including the first day.
