Atascadero is a city in San Luis Obispo County, California, about equidistant from San Francisco and Los Angeles on U-S Highway 101. Atascadero is farther inland than most other San Luis Obispo County cities, and as a result, usually experiences warmer, drier summers and cooler winters than neighboring cities such as San Luis Obispo and Pismo Beach. Nearby CA Highways 41 and 46 provide easy access to the Pacific Coast and the Central Valley of California. The population was 28,310 at the 2010 census. The brainchild of mega-entrepreneur E.G. Lewis, Atascadero is the result of nearly a century of organic community evolution. It is an amalgamation of rolling hills studded with oaks; historic buildings; quaint lake park and zoo; enclaves of artists, musicians and writers; all surrounded by visitor vistas and wineries.
