Luxembourg 5-Day Highlights Itinerary: Luxembourg City, Vianden & Mullerthal

Luxembourg, one of the world’s smallest yet wealthiest nations, is a hidden European treasure filled with dramatic gorges, fairytale castles, and a stunning UNESCO-listed capital. From the deep stone valleys and modern structures of Luxembourg City and the breathtaking Vianden Castle in the north to the hiking trails of Mullerthal (known as “Little Switzerland”), this 5-day highlights itinerary guides you through Luxembourg’s absolute best. Finding restaurants, checking train and bus times, and navigating medieval streets require a reliable mobile connection.
