Web site has it listed this time of year you should refer to the web page as tours are limited.
The previous two statements are correct, but, you should arrive a little early as they leave promptly. I arrived 15 minates early and was not disappointed. Enjoy.
Hours vary depending on the time of year. Tours are only may 1 thru Sept 30, with holiday tours in Dec. You should call and ask the tour hours for the day you plan to go.
