The Bale Mountains are mountain ranges in the Oromia Region of southeast Ethiopia, south of the Awash River, part of the Ethiopian Highlands. They include Tullu Demtu, the fourth-highest mountain in Ethiopia, and Mount Batu. The Weyib River, a tributary of the Jubba River, rises in these mountains east of Goba. The Bale Mountains National Park covers 2,200 square kilometers of these mountains. The park's main attractions are the wild alpine scenery and the relative ease with which visitors can see unique birds and mammals.
