Vaduz Castle, the official residence of the Prince of Liechtenstein, is perched on a hill overlooking the capital city of Vaduz. While the castle itself is not open to the public, visitors can enjoy a scenic walk around its grounds and capture stunning views of the Rhine Valley from the exterior. The castle is easily accessible from the city center with a steep, but rewarding, hike or a short drive. It's best to visit between spring and early autumn for pleasant weather conditions. Entry to the castle grounds is free, and you can explore the surrounding area comfortably in about an hour. To enhance your visit, consider joining a guided tour of Vaduz that includes historical and cultural insights, although navigating solo is perfectly feasible. As it remains a private residence, ensure you respect any restricted areas.
