As the first station outside of I-285 on the red line, the Dunwoody MARTA station is next to Perimeter Mall, putting it in middle of one of Atlanta's largest commercial and retail centers. Free daily parking and long-term parking for $5/day provide options for commuters, as do area shuttles that travel to office parks.
One of the first things that is noticeable about the station is that it is tall. About four stories high, there's a lot vertical movement getting to and from the station's three exits, which provide access to Hammond Drive, the parking garage, buses and Perimeter Mall. Under the train platform is the main concourse level, where the fare gates are located, and about two levels below that is street level. See below on how to best navigate the station.
Perimeter Mall Exit
After exiting the fare gates, keep to the right for a corridor that leads down to street level near the Perimeter Mall parking garage. There is a designated sidewalk for pedestrians though the parking area, which leads to Macy's. This exit also provides easiest access to Barnes and Noble, Container Store, Perimeter Place and Le Méridien Atlanta Perimeter Hotel via the mall parking lot.
Parking Garage Exit
Across from the fare gate is an exit to the parking garage. Local shuttles pick up in passengers here on lower levels, or take the stairs or elevator down to the first level for street access to Hammond Drive. This exit provides quick access to the shopping center across from the mall, which includes Old Navy, Best Buy and Marshalls. Across the street is also Chequers Seafood and Steak and the Marriott Perimeter Center (which features Hertz Rent-a-Car).
A few stories directly below the train platform is the bus bay, located within the station, so don't exit the fare gate. Three buses are located here: bus 5 (Hammond Drive to Roswell Road southbound to Buckhead) bus 87 (Hammond Drive to Roswell Road northbound to Roswell) and bus 150 (travels to area hotels and offices around the mall then to Mt. Vernon Road).
