Cayucos State Beach is a protected beach in the state park system of California, United States. It is located in Cayucos, San Luis Obispo County. The sandy beach environment supports uses of swimming and surfing.[1] Prehistorically this general area of the central coast was inhabited by the Chumash people, who settled the coastal San Luis Obispo area approximately 10,000 to 11,000 BCE, including a large village to the south of Cayucos at Morro Creek.[2] The 16acres park was established in 1940.[3]
