The Isar is a river in Tyrol and Bavaria. Its source is in the Karwendel range of the Alps in Tyrol. It enters Germany near Mittenwald, and flows through Bad Tölz, Munich, and Landshut before reaching the Danube. In my opinion the Isar Valley near Bad Tölz is one of the beautiful places in Bavaria. 3 weeks ago I made a trip trough it and I have to say it was stunning. In this Place the beauty of nature is reality. High Mountains, a lot of vegetation, a lot of birds and hundreds of small rivers ,which forms at the end the Sylvenstein reservoir, just beautiful.
But Enough said , Check it out yourself.
