Geography According to the United States Census Bureau, the census-designated place covers an area of 0.8 square miles (2.1 km2), all of it land. The original townsite of San Simeon is at San Simeon Bay, and was the important 19th-century shipping point with the successive wharves that were built. San Simeon Acres, about 4 mi south of the original townsite at the mouth of Pico Creek, and so about halfway between old San Simeon and Cambria, was established in the 1950s. Most of the development at San Simeon Acres was in the 1960s to the 1980s. Many motels and cafes serve visitors to Hearst Castle.
