Point Sur Lightstation is a lighthouse at Point Sur, California, 135 miles (217 km) south of San Francisco, on the 361-foot (110 m)-tall rock at the head of the point. It was established in 1889 and is part of Point Sur State Historic Park. The light house is 40 feet (12 m) tall and 270 feet (82 m) above sea level. As of 2016, and for the foreseeable future the light is still in operation as an essential aid to navigation. The lightstation is part of Point Sur State Historic Park. Point Sur is the only complete turn-of-the-20th-century lightstation open to the public in California. Three-hour walking tours guided by volunteers are available on Wednesdays and weekends throughout the year.
