Vianden Castle Explore the north of Luxembourg, a region full of steep valleys and breathtaking views. Discover the medieval town of Vianden and its imposing castle which attracts thousands of visitors annually. Admire the imposing castle that overlooks the town, the town wall with its fortified towers, and the town's chairlift. During this stop, you have 2.5 hours of free time to plan for yourself. We recommend that you bring a snack or a sandwich if you don't want to waste time in a restaurant. Otherwise, the time of the visit might be too short. 4.
