The Black Forest is a wooded mountain range in Baden-Württemberg, southwestern Germany. It is bordered by the Rhine valley to the west and south. Rivers in the Black Forest include the Danube (which originates in the Black Forest as the confluence of the Brigach and Breg rivers), the Enz, the Kinzig, the Murg, the Nagold, the Neckar, the Rench, and the Wiese. The Black Forest is part of the continental divide between the Atlantic Ocean drainage basin (drained by the Rhine) and the Black Sea drainage basin (drained by the Danube).
