Travel this morning to Heidelberg, the oldest university city in Germany. Learn about the riotous life of past students and enjoy views of the sandstone castle from the charming Old Town. Continue south, through the Black Forest region, which is bordered by the Rhine Valley to the west, and south. This beautiful area is renowned for woodcarving, the creation of the original cuckoo clock, and specialist cuisine that includes delicacies such as smoked ham and Black Forest Cake. Cross the border into Switzerland before stopping to admire the impressive Rhine Falls at Schaffhausen. Travel to central Switzerland and enter the scenic region of Lake Lucerne, your home for the next two nights. Later this evening, perhaps enjoy the fun and explore the city on your own after enjoying dinner at your hotel.
