Arnstorf is a small market town in the Rottal, the gently rolling country of Lower Bavaria between the Isar and the Inn. It is farming country through and through: maize, wheat, hop gardens here and there, big Bavarian farmsteads and onion-domed churches on every rise. The Rottal is also famous for horse breeding, and you may see paddocks of the sturdy Rottaler horses along the lanes.
The town has a fine little centre with a castle, the Schloss Arnstorf, owned for centuries by a noble family and still standing at the heart of the place. The market square is the kind where you will find a bakery, a butcher selling warm Leberkäse rolls at midday and an inn with a beer garden under chestnut trees. That is exactly what a food stop at the end of a long day should be.
Riding into the Rottal is relaxed and pleasant. The roads roll over low hills in long bends with good sightlines, and traffic is light away from the main routes between Pfarrkirchen, Eggenfelden and Landau. Surfaces are generally good, though farm vehicles drop mud in wet weather, especially at field entrances. This is not mountain riding, but there is real satisfaction in linking the small roads that thread between the villages, with the land opening and closing around you.
As a finish, Arnstorf is quiet and unpretentious. Fuel is available in town and in the larger neighbours, and the Rottal spa towns of Bad Birnbach and Bad Griesbach are not far if you want a warm thermal bath to ease the stiffness of a long ride. Order something hearty, a Schweinsbraten with dumplings and a local wheat beer if you are done for the day, and watch the evening settle over the fields.
