Castleberry Hill is an eclectic and artistic neighborhood just southwest of downtown Atlanta that hosts a regular art stroll (see area map). The closest MARTA station is the Garnett Station on south red/gold line, though it is about a three block walk in a transitional area.
If you plan to bike or walk from Garnett, take the Trinity Street exit out of the station and turn left on Trinity. Keep right at the split in the road and go up and over the bridge. At this point, the street changes to Peters Street, which forms the edge of the neighborhood.
