Isar
river in Bavaria, Germany. It is a tributary of the Danube and 283 km in length. The name Isar appears to be derived from the Celtic word Isaria (meaning torrential).
The source is located on the German-Austrian border in the Bavarian "Karwendel" (a part of the Alps), near the town Mittenwald. From there the river runs northwards, directly through the Bavarian capital Munich and northeastward to Bad Tölz, Wolfratshausen, Munich, Freising, Moosburg, Landshut, Dingolfing, Landau and Plattling.
