Mikumi National Park borders Selous Game Reserve on the south, the two areas forming a unique ecosystem. Two other natural areas bordering the national park are the Udzungwa Mountains and Uluguru Mountains. Malundwe Mountain is within the park, the highest of a belt of hills that run east and west through the park, connecting the Uluguru Mountains to the northeast with the Uvidunda and Udzungwa mountains to the west. Malundwe Mountain consists of three peaks along a ridge running north and south. Malundwe's south peak is the highest point in the park, reaching 1290 meters elevation.
