SR 103 travels primarily through eastern Geneva County. It is one of numerous highways that enter Alabama from the Florida Panhandle. Upon entering Alabama, the highway heads northward, traveling primarily through rural areas of the county along a two-lane roadway. At the approximate halfway point of the highway, it travels through Slocomb, the only incorporated community along its length.
