East Bay, Coastal region in San Francisco Bay Area, United States
East Bay is a region along the eastern shore of San Francisco Bay in California. It covers Alameda County and Contra Costa County, with cities, rolling hills, and farmland spreading inland from the waterfront.
Spanish settlers called the eastern shore 'Contra Costa' in the 1770s, meaning opposite coast. This name later became the title of the northern county in the area.
The name comes from its position east of the bay, which residents use to identify their home area in everyday conversation. People commute between neighboring towns for work and leisure, creating a shared sense of connection across the counties.
Visitors reach the cities through a network of trains, buses, and several highways connecting the counties. Travelers moving between towns should expect traffic during rush hours, especially on routes crossing the bay.
