San Luis Obispo County is a county located along the Pacific Ocean in the Central Coast of the U.S. state of California, between Los Angeles and the San Francisco Bay Area. As of 2000 its population was 246,681. The county seat is San Luis Obispo, with about 46,000 residents.
The county's distance from the large metro areas of San Francisco and Los Angeles has helped it to retain its rural character and reminders of old California abound. Commonly referred to as "the Central Coast," the area is more rural and agricultural than many other coastal regions in California. Father Junipero Serra founded the Mission San Luis Obispo de Tolosa in 1772 and the Mission is today an active part of downtown San Luis Obispo (popularly referred to as SLO or SLO-town). The small size of the county's communities, scattered along the beaches, coastal hills, and mountains of the Santa Lucia range, provides a wide variety of coastal and inland hill ecologies to support many kinds of fishing, agriculture, and tourist activities.
The mainstays of the economy are California Polytechnic State University with its almost 20,000 students, tourism, and agriculture. San Luis Obispo County is the third largest producer of wine in California, surpassed only by Sonoma and Napa Counties. Wine grapes are by far the largest agricultural crop in the county, and the wine production they support creates a direct economic impact and a growing wine country vacation industry.
The town of San Simeon is located at the foot of the hill where newspaper publisher William Randolph Hearst built the famed Hearst Castle. Other coastal towns include Cambria, Morro Bay and Cayucos to the north of San Luis Obispo city, and Avila Beach and the Five Cities to the south: Arroyo Grande, Grover Beach, Oceano, Pismo Beach and Shell Beach. Nipomo, just south of the Five Cities, borders northern Santa Barbara County. Inland, the cities of Paso Robles, Templeton, and Atascadero lie along the Salinas River, near the Paso Robles wine region. Just south of Cambria lies Harmony, one of the smallest towns in California with a population of 18.

The prehistory of San Luis Obispo County is strongly influenced by the Chumash people who had significant settlement here at least as early as the Millingstone Horizon thousands of years before the present age. Important settlements existed, for example, in many coastal areas such as Morro Bay and Los Osos.[1][2]
Mission San Luis Obispo de Tolosa was founded on September 1, 1772 in the area that is now the city of San Luis Obispo.
San Luis Obispo County was one of the original counties of California, created in 1850 at the time of statehood.
The Salinas River Valley, a region that figures strongly in several Steinbeck novels, stretches north from San Luis Obispo County. The remote California Valley near Soda Lake is the region most untouched by modernity. Travels through this area and the hills east of highway 101 during wildflower season are very beautiful and can be incorporated with wine tasting at local vineyards.
According to the U.S. Census Bureau, the county has a total area of 3,616 square miles (9,364 km²), of which, 3,304 square miles (8,558 km²) of it is land and 311 square miles (806 km²) of it (8.61%) is water.

San Luis Obispo County is served by Amtrak trains and Greyhound Lines buses. The San Luis Obispo Regional Transit Authority provides countywide service along US 101 as well as service to Morro Bay, Los Osos, Cambria and San Simeon.
The cities of San Luis Obispo, Atascadero and Paso Robles operate their own local bus services; all of these connect with SLORTA routes.
Intercity service is provided by Amtrak trains, Greyhound and Orange Belt Stages buses.
