Just south of the border with France and Switzerland lies Germany's sunniest state, Baden-Württemberg. Thanks to its beautiful countryside, Baden-Württemberg is a very popular travel destination for van and motorhome travellers. To the north lies the romantic city of Heidelberg. Its castle, partly in ruins, majestically dominates the town and is one of the country's most popular sights. Stroll along the Neckar, where many famous Romantic poets and painters have passed. To the southwest lies the Black Forest, with its hills, forests, streams and traditional villages reminiscent of fairy tales. Visit the charming towns of Freiburg and Baden Baden. Be sure to treat yourself to a piece of the famous Black Forest cake when you visit the forest. The state capital, Stuttgart, is famous for its role in the automotive industry. A must-see during a motorhome break in Stuttgart is the Mercedes-Benz Museum and the Porsche Museum. In the far south, you'll find Germany's largest lake, Lake Constance, a popular travel destination. Sit along the shore and enjoy the breathtaking view of the Swiss Alps in the background. If you're traveling with children in a motorhome in Baden-Württemberg, take a trip to Germany's biggest theme park, Europa-Park.
