Yolo County

Yolo County is an administrative area in the Sacramento Valley of northern California, with Woodland serving as its seat of government. The landscape ranges from flat fields to rolling hills, crossed by two major highways that link its main towns.

The area became an administrative unit in 1850 when California joined the Union, taking its name from the Patwin language of the original inhabitants. During the 19th century, the region shifted from sparse settlement to a farming zone with permanent towns along trade routes.

The university campus in Davis draws students and researchers from around the world, giving the area a youthful and international atmosphere. Many residents work in farming or education, blending rural traditions with academic openness across the region.

Interstate 5 runs north to south through the area, while Interstate 80 cuts across the southern section heading east. Visitors find most facilities and services in the four towns, especially Davis and Woodland, both easy to reach by car.

The tomato harvest here supplies a large share of the entire United States production, turning the flat fields into a sea of red fruit each summer. Many processing plants stand right next to the growing areas, so the crops move quickly from field to factory.
