Hearst Castle is the ranch retreat of publishing magnate William Randolph Hearst. Built in the first half of the twentieth century, Hearst Castle is now part of the California State Park system. Tours are available daily. Located along the central coast of California near the town of San Simeon in the county of San Luis Obispo, the park is truly an amazing place to visit. There are several tours available to see various sections of the massive estate. We toured the downstairs rooms which included the living room, dining room and game room. Once the tour is complete, you are free to roam the grounds of the estate.
