the vils
The Vils rises in Kleinschönbrunn in the market town of Freihung in the district of Amberg-Sulzbach. On its first five kilometers, it initially flows north-northeast towards Freihung. At the south-west edge of the town, it turns abruptly to the west and crosses the densely wooded landscape with the Forstlohe in the south and the Grafenwöhr military training area in the north, crossing into the district of Vilseck.
There it turns south-southeast and then flows through the districts of the market town of Hahnbach and the municipality of Poppenricht. Then, on its middle course, it crosses the independent city of Amberg, the largest town on its banks. In a constant direction, it runs through the districts and main towns of the municipalities of Kümmersbruck and Ensdorf.
When it enters the area of Markt Rieden, it continues to flow approximately to the south and then, in the following Markt Schmidmühlen, from the right takes in the Lauterach, which is almost 35 kilometers long and by far its longest tributary. On the rest of the lower course, the Hohenfels military training area in the district of Neumarkt in der Oberpfalz borders on the right, which is briefly opposite the urban district of Burglengenfeld in the district of Schwandorf. It then flows into the lower Naab after about 87 kilometers at the market town of Kallmünz in the district of Regensburg.
