San Luis Obispo County
San Luis Obispo County  is in California's Central Coast region. The county seat is San Luis Obispo (population 48,825), home to California Polytechnic State University (Cal Poly) with 20,000 students. The county is the third largest wine producer in California, behind Sonoma and Napa counties. It has a number of coastal towns. A major attraction is Hearst Castle at San Simeon.
The major airport is in San Luis Obispo. Scheduled flights are available to and from San Francisco, Los Angeles, and Phoenix on United  (operated by SkyWest  as United Express) and USAirways  (operated by Mesa  as USAirways Express). Prices start around $200 for a ticket purchased separately, but are much less expensive when combined with flights going through San Francisco or Los Angeles. There is an airport in Paso Robles, but it has no commercial service.
Amtrak  has train stations in San Luis Obispo, Paso Robles and Grover Beach. Coast Starlight goes from Seattle to Los Angeles stopping at Paso Robles and San Luis Obispo within this county. The Pacific Surfliner goes from San Luis Obispo to San Diego and makes all stops. There is connecting bus service to other places statewide including the Bay Area, Los Angeles, and the Central Valley. Make sure you leave plenty of time because it can take up to 7 hours to get to SLO from San Francisco and 8 hours to get to SLO from San Diego, although the spectacular delays frequent in the past have abated significantly following recent agreements with freight rail carriers.
Greyhound  offers bus routes into SLO County. Once again set aside time because the trips can be long but Greyhound is one of the cheapest ways to go.
If coming from the north or south, Highway 101 is the fastest route. Travel times from the Bay Area or Los Angeles are about four hours. An alternate route from the Bay Area is to take State Route 1 down the coast. It is a senic drive, but is winding and slow and takes about six hours. Travelers who begin in the Central Valley, like Bakersfield or Fresno, need to take Route 46 or 41 to SLO County.
Driving is a quick way to get to your destination.
Paso Robles, Atascadero, Morro Bay, San Luis Obispo and the 5 Cities region each have their own intra-city bus routes. Getting around the county requires the Regional Transit Authority.
