Passau to Regensburg and Ingolstadt: Private day trip

Dating back to pre-Roman times, Regensburg was one of the most important cities in the region for centuries, sitting on key trade routes, and serving as the starting point of Christianization of the Czechs. Reminders of the city's medieval golden days abound in the UNESCO-listed Old Town. Covering nearly 200 hectares and 1500 buildings, the historic city center is reached by crossing the 13th century stone bridge that made Regensburg wealthy. Near the foot of the bridge you'll find one of the city's most unassuming but important landmarks: the Sausage Kitchen, which has been serving its signature wursts and mustard since 1146. Nearby, St. Peter's Cathedral is considered the premier Gothic monument in Bavaria, famed for both its architecture and the heavenly voices of its Boys' Choir. Meander through the picturesque Old Town for a few minutes, and you'll reach the Thurn und Taxis Castle. A 13th century Benedictine monastery that was converted into a residential palace, it's bigger than Buckingham Palace, and offers a unique blend of architectural styles, such as the 11th century Basilica with a lavish Rococo makeover.

Located on the banks of the Danube River, the fortified city of Ingolstadt presents visitors with an exciting mix of past and present. Mary Shelley chose Ingolstadt as the setting for her novel Frankenstein and the Frankenstein themed tour of the Old Town is always popular with tourists. In contrast, this innovation guided city is home to the Audi Forum Ingolstadt, which is visited by over 500,000 people each year. The Audi manufacturing plant has factory tours available while the Audi Museum is a must-see for car enthusiasts, where a vast range of modern, classic, and vintage automobiles are on display. Both visitor experiences offer the best of German technology, design and innovation. If that’s not your cup of tea, then Ingolstadt provides the perfect opportunity to indulge in some retail therapy with its small, sophisticated privately-owned shops and boutiques set in the bustling and lively Old Town.
