San Simeon, California: Hearst's XanaduThe remote hilltop pleasure castle of tycoon William Randolph Hearst is so vast that it requires ten different tours to see it all (But you can hit the high points with just one). Bring lots of free time and a sense of inferiority.
Visitor Tips and News About Hearst's Xanadu
Terrifying truck up to the castle. Rode a bus that seemed almost too large for the road. I was scared, but beautiful drive.[Lindsay Gurley, 12/11/2015]
Tour 1 is a good one for your great photo ops. The film they show is good, too.[Kim, 04/30/2010]
Tycoon William Randolph Hearst's opulent castle is a very popular tourist attraction, but its over-the-top, garish decor qualifies as an oddity. Prerequisite: Watch the movie Citizen Kane, then come here. Ask the tour guide annoying questions about the movie.
