The Uvidunda mountains are part of the Eastern Arc Mountains. The range consists of a single block with three distinct peaks, Chonwe, Mgwila, and Migomberama, which exceed 1500 meters elevation. The Rubeho Mountains are close to the northwest, and the Udzungwa Mountains are immediately to the southwest across the Great Ruaha River. Southeast of the mountains the Great Ruaha river emerges onto a plain. Malundwe Mountain lies to the east in Mikumi National Park. The Mkata Plain opens to the northeast.
