The Sarajevo Canton has a typical Bosnian geography. It is located close to the geometric center of the country, and contains numerous mountains, including Bjelašnica, Igman, Jahorina, Trebević, and Treskavica. The cities of the Canton are built predominantly on the hills at the foot of these mountains, and the fields in between them. The most significant of these is the Sarajevo field, a small depression upon which the bulk of the city is built upon. The Miljacka river passes through the Canton. Vrelo Bosne, the source of the Bosna River, is found in Sarajevo Canton and is the source of water for most residents of Sarajevo.
