The Carter Center is just outside downtown in a residential area and features a permanent Jimmy Carter exhibit as well as rotating exhibits. There is a bus stop right next to the Carter Center, making it fairly easy to get to. It is also about a 20-25 minute walk from the Inman Park Station on the blue/green rail line.
Bus 16 is the route that goes to the Carter Center, which you can board at the Five Points station on Alabama Street as well as any stop on Peachtree Street from the Five Points station north to Auburn Avenue along Woodruff Park. You can also catch the bus about a block away from the Peachtree Center Station (see area map).
The recommended route would be to take a north/south line train to the Peachtree Center station and follow the signs to the Harris Street exit. After exiting the fare gate, tap your Breeze Card and follow the signs to Peachtree Street east. At street level, turn right to walk along Peachtree Street then make the first right onto Harris Street and walk one block to Peachtree Center Avenue. Look for any bus stop sign on Peachtree Center Avenue and wait there for the bus. It is best to check schedules ahead of time as routes can be upwards of 20-30 minutes apart.
Once on the bus, you can let your driver know your destination. You will know you are getting close to the Carter Center when it looks like the bus is getting on an interstate ramp. Once the bus goes around a large curve and enters the residential area, the stop for the Carter Center is next. To return, you’ll have to wait for bus 16 on the opposite side of the Carter Center (see bus stop map).
The walk to the Carter Center from the Inman Park Station is very pleasant, with the option to view historic Victorian homes and parks, though the route is hilly. Take a blue or green line train to the Inman Park Station and keep right after exiting the fare gate, following the signs to Inman Park. At street level, turn right and walk along the parking lot to reach a sidewalk marked “The PATH”. Turn left on the PATH and follow it all the way to the Carter Center. The sidewalk winds through rolling hills, and you will go past a playground then cross over Euclid Avenue, Lake Avenue and N. Highland Avenue. Keep right as the path splits beyond N. Highland. The top of the hill in the trees is the Carter Center (see walking map).
