Ten miles north of Cambria, hilltop Hearst Castle is California's most famous monument to wealth and ambition. William Randolph Hearst, the newspaper magnate, entertained Hollywood stars and royalty at this fantasy estate dripping with European antiques, accented by shimmering pools and surrounded by flowering gardens. Tours last 1¾ hours, including the round-trip bus ride. Make reservations, especially for evening living- history and Christmas holiday tours.
