Oberlauf der Östlichen Günz in Obergünzburg

Upper reaches of the Östliche Günz in Obergünzburg

The Günz is an approximately 55 km long right tributary of the Danube in the Upper Swabian Alpine foothills in Bavaria.


The name is said to derive from the Indo-European “*gheu” – “to pour” – in the sense of “watery river”.[2]


The Günz originates near Lauben in the district of Unterallgäu from the confluence of the Western and Eastern Günz and flows mainly in a northerly direction. It flows into the Danube from the right at Günzburg.

The Günz cold period, one of the main alpine glaciation periods, is named after the Günz.

Source Flows

Western Günz

The Westliche Günz is 19 km long and rises west of Obergünzburg in the municipality of Untrasried. It flows through Ottobeuren. In Westerheim it passes under the federal motorway 96 and then joins the Östliche Günz near Lauben.
