Solano County

Solano County stretches across California territory between Sacramento and San Francisco Bay, covering land and water surfaces. The terrain connects two major metro areas through valleys, hills, and shoreline zones along rivers and tidal straits.

The administrative division formed in 1850 as one of California's original counties at statehood. Fairfield later became the seat of government, replacing earlier locations, while military installations expanded after World War II.

The name honors Chief Sem-Yeto, baptized Francisco Solano by Mexican missionaries, who led the Suisunes in the early 19th century. Residents today use waterways for recreation, and ferries connect towns along the bay shoreline.

Interstate 80 crosses the area from east to west, linking all major towns. Public buses and ferry services run between waterfront communities and surrounding regions, so visitors can reach multiple locations in a single day.

The bay shoreline runs through flat marshland that offers important stopover sites for migratory birds in autumn and winter. Some towns sit right at the edge of these wetlands, where visitors can watch waterfowl gather to feed.
