The Hearst Castle is really something. Last time I was there, there were 2 different tours because the place is so huge. It's fun to imagine the type of Hollywood actors and characters who used to frequent the house. The tours are well done. I'm looking forward to taking our 11 and 12 year old now that they're old enough to comprehend this type of thing. The official website, hearstcastle.org shows you much more than I could explain.
