The Drina originates at the point of confluence of the rivers Tara and Piva, between the slopes of the Maglić, Hum and Pivska Planina mountains, and the villages of Šćepan Polje (in Montenegro) and Hum (Bosnia and Herzegovina). At its origin, it flows west, then makes a long curve to the northeast, around the Maluša mountain. From here it is northbound, in terms of general direction, for the rest of its journey toward the Sava. Here, in its headwaters, the Drina receives the Sutjeska river from the left.
