East Bay

Lying across the Bay Bridge from San Francisco, the East Bay consists primarily of Contra Costa County and Alameda County. It has a unique culture that's more laid back and uncomplicated than its Western neighbors. Oakland, the area's largest city, is famous for its somewhat smaller Chinatown and its beautiful waterfront Jack London Square, as well as its large port and eucalyptus-spotted hills. Berkeley, just north of Oakland, is home to the University of California and tens of thousands of students.


  Contra Costa County
Contra Costa County is a primarily residential county that offers a vast array of food, shopping, and lodging options for Bay Area visitors. The landscape is dominated by Mount Diablo, a peak that provides excellent hiking opportunities and, on clear days, summit views that stretch for well over 100 mi (160 km) in all directions. Other attractions include the John Muir Historic Site in Martinez, the estate of Nobel winning playwright Eugene O'Neill in Danville, and a WWII shipyard, now a national historic site, in Richmond.
  Alameda County
The densely populated northwestern part of Alameda County is home to the many parks and museums of Oakland, the counter-cultural hub that is Berkeley, and even a historic aircraft carrier in Alameda. The county's southern region provides a chance to experience dozens of immigrant communities, particularly in Fremont, while the eastern part of the county is rural, with the windmills and rolling hills surrounding Livermore offering opportunities for outdoor activities.

Other destinations[edit]

  • 1 Del Valle Regional Park - This East Bay Regional Park District park surrounds Lake Del Valle, and includes wilderness areas with canyons, woodlands, grasslands, and some quite dramatic rock formations.
  • 2 Mount Diablo State Park - This 20,000-acre (80 km2) park provides great hiking opportunities on a mountain that dominates the landscape for most of central and eastern Contra Costa County. It offers an incredible viewshed, with views on clear days stretching 181 mi (291 km) to Mount Lassen.


Aerial of the Tri-Valley

What the locals call "the East Bay" is really two fairly distinct regions separated by the East Bay hills. On the bay side of the hills in the west, the cities of Berkeley, Oakland, San Leandro and Hayward rise from the edge of the San Francisco Bay up the western face of the foothills. The climate tends to be temperate, the culture diverse, the transit frequent, and the traffic horrendous.

On the eastern side of the hills, the towns of Walnut Creek, Pleasanton and Livermore lie in the area known as the Tri-Valley region (named for the Livermore, San Ramon and Amador valleys). The climate here is more like that of the San Joaquin Valley, with foggy winters and scorching summers. The population is more homogeneous, but the traffic is still pretty awful in some places and during the rush hour. Originally, when the small towns of the Tri-Valley area began to grow into suburbs in the 1970s, many people commuted over the hills to work in the South Bay, the Peninsula or the City. Today, many large corporations have offices in the Tri-Valley area, and the suburbs of Pleasanton and Walnut Creek are growing into small cities.

Contra Costa County is divided into three parts simply referred to as: "West County" near Richmond, "Central County" for the booming area near Walnut Creek, Concord, and Mount Diablo, "East County" for the area near the Delta which includes Antioch or Brentwood.

Though pro sports have seen a dramatic exit from the area, the East Bay has two NCAA Division I sports programs:

  • The California Golden Bears field teams in 30 sports. Through the 2023–24 school year, most teams play in the Pac-12 Conference, but that league was the main casualty of the early-2020s conference realignment. Despite the geographic oddity, the Bears will join the Atlantic Coast Conference for 2024–25 and beyond. Most Cal sports venues on campus, with the most notable being the ancient Memorial Stadium (football), which sits right over the Hayward Fault.
  • The Saint Mary's Gaels, representing Saint Mary's College in Moraga, field teams in 19 sports, mostly in the West Coast Conference. Unlike Cal, Saint Mary's doesn't have a football team. Men's basketball is the hot-button sport here, with NCAA tournament appearances not unheard of.

Get in[edit]

By plane[edit]

The only major airport in the East Bay is Oakland International Airport (OAK IATA) in Oakland. San Francisco International Airport (SFO IATA) across the Bay and San Jose's San Jose International Airport (SJC IATA) in the South Bay are the other major airports in the area.

By car[edit]

Bridges connect the East Bay with Marin County, San Francisco, and the Peninsula. Also, the I-580 connects the Central Valley with the East Bay via Altamont Pass in the east.

By public transportation[edit]

BART connects the East Bay with San Francisco, and Amtrak serves this region as well.

Bus service, provided by Golden Gate Transit, is useful for entering the region from the North Bay; buses from Marin County stop in or near Richmond.

Get around[edit]

I-880: don't be fooled, this is in good traffic

By car[edit]

Due to the population exodus from "The City" (due to $$$ high prices and low bang for the buck) and the movement of some families from the west side of the hills, the eastern portion of the East Bay is growing very rapidly and the traffic has gotten worse over the years.

There are several freeways in the East Bay, including the I-80, I-580, I-680, and the I-880. However, the large number of commuters from Stockton, Tracy, the Tri-Valley, and the Fremont area to Silicon Valley can mean that southbound traffic is poor in the weekday mornings and northbound traffic is poor during late afternoons and evenings.

By public transportation[edit]

BART lines in the East Bay radiate out from Oakland after crossing the Bay from San Francisco; this makes them useful for certain journeys around the area, especially if origin or destination is near Oakland. However, the main purpose of BART for East Bay inhabitants is to get to San Francisco, not around the East Bay.

AC Transit bus service is useful for getting around dense urban parts of the East Bay (Oakland, Berkeley, Alameda), but is less practical in some areas.


Lake del Valle in the southeastern East Bay

The local scenery consists of some rolling peaks, higher mountains, and wooded regions in the west. Mount Diablo sticks out like a sore thumb toward the north; in the south, generally the mountains are parts of ridges, so they do not stand out so much. The picture on the right is a fairly good example of countryside on the southern side of the East Bay.

The urban areas in the west of the East Bay can be gritty, but there are some quality museums, interesting cityscapes, and vibrant arts scenes. UC Berkeley is a highlight.



The East Bay Regional Park District maintains 65 parks across the East Bay, ranging from easy access picnic areas to off-limits wildlife sanctuaries. More than a dozen campsites range from "family camping" to backpack areas.

Berkeley and Oakland have frequent events, and the outer parts of the region have some as well, like the Alameda County Fair in Pleasanton.

Travel topics[edit]


The University of California, Berkeley (often called "UC Berkeley" or just "Cal") is world renowned for its educational standards and its liberal viewpoint of most things. There is a Cal State school in Hayward (CSU East Bay - formerly known as "CSU Hayward"). There are many two year junior colleges here but one of the biggest is Diablo Valley College, in Pleasant Hill.


There are many malls and shopping centers in the east bay. Sunvalley Mall (Concord), Stoneridge Mall (Pleasanton), Bay Fair Mall (San Leandro), Newpark Mall (Newark), Southland Mall (Hayward), and Hilltop Mall (Richmond) are some of the largest.


The two main area codes are (510) for Western Alameda county and the "West County" region of Contra Costa, and (925) for central and east Contra Costa County and for the central eastern part of Alameda county near the fairgrounds Pleasanton and Livermore.

  • South Bay – this is where San Jose and Santa Clara can be found, and is known for being a major center of technology.
