The Isar - a very special river. The Upper Isar and its floodplains are among the best preserved and therefore most important wild river landscapes in Germany.
The Isar has a total length of around 295 kilometers and has its source in the Karwendel Mountains in the Hinterautal (Tyrol). It is the fourth largest river in Bavaria after the Danube, Inn and Main. In Moosburg the Amper flows into the Isar, which then flows into the Danube in Deggendorf.
Like the Loisach, the Isar used to be a trading route and was used by raftsmen for the transport of goods, people and for the wood drift. The starting points of the rafting were among others the places Mittenwald, Krün, Lenggries and Tölz. The connection to Munich, Freising and Landshut was considered an important trade route. In the 19th century, around 8,000 rafts landed in Munich every year. Today the raft trip on the Isar is - in addition to numerous rubber dinghies - a popular leisure activity that is not always good for nature.
The sections of the route from the source on the Austrian side to shortly before Mittenwald and north of Krün to above the Sylvenstein reservoir are particularly close to nature.
