This morning enter the Main-Danube Canal and relax during a leisurely cruise through the beautiful Altmühl Valley. The Main-Danube Canal straddles the Franconian Alps via 16 locks, truly a fascinating feat of modern engineering. The highest point, the Continental Divide, is 435 metres above sea level. In the afternoon enjoy a guided tour of Nuremberg, a medieval city that played a significant role in World War II. See the storybook 900-year-old ramparts that surround this historic city, the Imperial Castle and the Justice Palace where the War Crimes Tribunal sat in 1946, before returning to the ship, moored in Nuremberg overnight, for dinner.
