Free entry to the interior of Neuschwanstein Castle is primarily reserved for children and teenagers under the age of 18, provided they are accompanied by a parent or adult supervisor. As of 2026, students over 18 from general education schools (such as high schools) are also eligible for free admission upon presentation of a valid student ID card. Additionally, essential companions for guests with disabilities are admitted free of charge if the necessity of an escort is officially noted in their disability documentation. It is a common misconception that everyone can enter the grounds for free; while you can walk up the hill to the castle courtyard and view the exterior and the famous Marienbrücke (Mary's Bridge) without a ticket, you must have a ticket to enter the castle for a guided tour. Even "free" tickets for children carry a small service fee (approximately €2.50) if reserved online, which is highly recommended since tour slots often sell out weeks in advance. Group leaders and teachers accompanying school classes also typically receive complimentary admission to facilitate their duty of supervision.
