Historic Highway 101 stretches from the California-Oregon state line down into the heart of Los Angeles. Following the California coastline for a majority of its route, Highway 101 has become a world-famous road-tripping route due to its excellent views and generally spectacular weather. Pacific Coast Highway aka PCH or CA State Route 1 follows Highway 101 concurrently down the coast and meets for a 54-mile stretch through Santa Barbara and Ventura County.
