The Kehlheim Region is part of the "Naturpark Altmühltal" (natural park in the valley of the Altmühl). It is dominated by the river Danube.
Don't miss a boat ride through the so called "Donaudurchbruch". The Danube cuts through the rocks of the "Fränkische Jura".
Somebody told me that many years ago the movie "River of no Return" was filmed in this area. However, I can't confirm that.

If you love hiking you will have the possibility to take unforgettable shots.

Make a stop at the famous "Kloster Weltenburg", one of the oldest monasteries in Bavaria. It is located directly on the shores of the Danube. Visit the church "Asamkirche" and enjoy a hearty meal after and try the famous dark beer which is brewed by the monks.

The complete region is a preferred destination of bikers (bicycles). You see them everywhere. Check out whether rental is available and combine exercise with sightseeing.
Ask for detailed information, take your swim wear with you if you want to relax in one of the hot springs in Bad Abbach or Bad Gögging.
Visit the area around Abensberg to see how hops is grown.
