Bojnice Castle, a stunning fairy-tale castle in Slovakia, is primarily visited through mandatory guided tours, offering deep insights into its history and architecture, though parts of the grounds can be explored solo. While generally accessible, some older sections may have stairs; it's best to check the official website for specific accessibility details, especially for wheelchair users. The castle is open year-round, but operating hours extend significantly during the peak summer season, and special events like the International Festival of Ghosts and Monsters occur annually, typically in spring. Expect an approximate cost of €10-€15 for adult entry, with additional fees for photography or special exhibits. A typical visit duration ranges from 1.5 to 3 hours, allowing ample time to explore the castle's romantic interiors, its adjacent park, and the unique travertine cave beneath. Visitors should note its proximity to Bojnice Zoo, making it a popular combined destination.
