Your first stop is Harburg, one of the oldest, largest and best preserved castles of Southern Germany. It was an important military stronghold during the 11th and 12th centuries. Through the Swabian crater landscape passing Dinkelsbuhl, you will arrive in Rothenburg, a preserved medieval town in Europe. Spend about three hours in Rothenburg, with plenty of time for sightseeing, lunch, and shopping.
A popular attraction is the Kathe Wolhfahrt Christmas Store on Herrngasse, a large store open year round where you can purchase ornaments, nutcrackers, and other Christmas items. Many of the highlights in Rothenburg are centered around Marktplatz, such as the Town Hall with its Rothenburg History Museum, and St Jakob's Church, a Gothic building with soaring ceilings filled with light.
You will return to Munich via the Hallertau, the world's largest hop-growing area.
