With half a million people, Nuremberg is Bavaria's second largest city. While its history dates to the 11th century, Nuremberg is most often linked to the 20th century (specifically World War II). It first served as the site of many pre-war Nazi rallies, then was nearly levelled by Allied bombing, then was the site of the famous post-war Nuremberg Trials. The city has much to offer today's visitors, including the rebuilt Nuremberg Castle and the world-famous gingerbread at Hauptmarkt. Hansel and Gretel would have loved this place.

Named by American soldiers during the post-World War II occupation years, the Romantic Road is a 200-mile-plus section of one of Germany's most picturesque highways, stretching from Würzburg in Bavaria's north to Füssen near the Austrian border.

Bike tours along the route are quite popular, and bus tours are also available.

Founded by the Romans in 179 AD as Casta Regina (meaning Fortress by the River Regen), Regensburg is one of Germany's oldest towns. It was relatively spared from Allied bombings during World War II. Today, many flock to see the wonderfully intact old city and its many medieval structures. The 12th-century Stone Bridge was used by Crusaders en route to the Holy Land. The Regensburg Cathedral (or Dom St. Peter) is one of southern Germany's finest examples of Gothic architecture.
