Arabia Mountain, a part of Arabia Mountain National Heritage Area, is the northern of two peaks in the Davidson-Arabia Mountain Nature Preserve, in DeKalb County, Georgia. A low saddle separates it from Bradley Mountain, several hundred feet to its south. The two form a monadnock. The peak is 955 feet (290 m) above sea level, rising 172 feet (52 m) above Arabia Lake reservoir. Bradley Mountain is closer to the visitor trails than Arabia Mountain and is often misidentified by visitors as Arabia Mountain.
