The guided tour with English interpretation is provided at 10:30 and 14:30 twice a day. It takes about an hour, but that excludes the Secret Garden. For the rear garden, the interpretation service is scheduled at 11:30 and 15:30. About one hour and a half will take to see the garden. The palace is closed on Mondays.
