Allow 1-2 hours for your self-guided tour with a free audio app that guides you or follow its signage. No appointment is necessary. The parking lot is at the bottom of the hill. Walk up or catch a fun ride in one of the "Castle Cars" to the Visitors Center (white house outside the gates).
General admission is $25, with all military, students, and children under 18 years old only $20.00. Please note the castle is not handicap-accessible, nor for persons with limited mobility. Stairs and inclines are involved.
