Vianden Castle, a magnificent medieval fortress in Luxembourg, is largely accessible on its lower levels and courtyard, though upper sections involve stairs; a lift may aid some mobility challenges. Visitors can enjoy a self-guided tour with available audio guides, or opt for pre-arranged group tours, with solo exploration being very popular. The castle is open year-round, but operating hours vary seasonally, typically extending in summer. Entry costs around €10-€12 for adults, with discounts for various groups, and a typical visit lasts between 1.5 to 2.5 hours. Perched atop a hill, it offers breathtaking views of Vianden town and the surrounding valley, making comfortable shoes advisable for exploring its extensive grounds and historical exhibits.
