Contra Costa County

From Wikivoyage
Jump to: navigation, search

East of the Oakland Hills that border the East Bay, Contra Costa County maintains a very separate culture and lifestyle than its Bay Area neighbors. The area is mostly residential—although many San Francisco businesses have moved here to avoid high city taxes—and affluent, and consequently considerably more conservative (by Bay Area standards). The same hills that keep Contra Costa culturally isolated also keep it protected climatically; the area is usually 10-20°F warmer than the Bay.

Cities[edit]

Map of Contra Costa County

Note that Lafayette, Moraga, and Orinda, due to their strong similarities, are often collectively referred to by locals as "Lamorinda."

Other destinations[edit]

  • 1 Mount Diablo State Park - This 20,000 acre 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 miles to Mount Lassen.

Understand[edit]

Get in[edit]

By car[edit]

State Route 24, through the venerable Caldecott Tunnel, is the main entrance to Contra Costa from San Francisco, Oakland and Berkeley. Interstate 680 is the main route linking Contra Costa to the South Bay and Silicon Valley to the south, and to Sacramento to the north. Interstate 580 links Contra Costa to central Alameda County to the west, and to Stockton and the Central Valley to the east.

By plane[edit]

There are no major airports in Contra Costa County with regularly scheduled passenger service, though there are several general aviation airports. One must either use the Bay Area airports serving San Francisco, Oakland, or San Jose, or the Central Valley airports serving Stockton or Sacramento. The county also has two airports that are not currently providing passenger service:

  • Buchanan Field Airport, located in Concord
  • Byron Airport, located two miles (3 km) south of Byron

Get around[edit]

BART serves Orinda, Lafayette, Walnut Creek, Pleasant Hill, Concord, and Pittsburg. BART stations have bus service as well. Paratransit (for disabled riders) in Contra Costa is quite good, but you must sign up for it with County Connection LINK and you must reserve your rides in advance.

In general, rush hour/commute times in Contra Costa feature traffic jams on the freeways and crowded BART trains.

See[edit]

The 'mothball fleet', a group of ships mostly from the World War II era, sits just east of Martinez. The ships are being stored rather than dismantled. Among the ships there is the Glomar Explorer, built by Howard Hughes for the US Government to scavenge a sunken Soviet Submarine. The fleet is visible from vista points along Interstate 680 on the north side of the Martinez/Benicia bridge (actually Solano County).

Do[edit]

Contra Costa has many parks and trails, as well as reservoirs and house museums managed by the East Bay Regional Parks System, East Bay MUD (Municipal Utility District = the local water company), designated Open Space areas, Mt. Diablo State Park, etc. There are also many performing arts venues, including the Chronicle Pavilion in Concord. The California Delta offers plenty of water activities.

Stay safe[edit]

Richmond has high rates of homicide, robbery, assault, rape, carjacking, and other violent crimes, and visitors should exercise extra caution. Fire dangers at refineries in the county have on rare occasions caused alerts where residents were told to "shelter in place" and avoid unnecessary outdoors excursions due to the potential for hazardous fumes - if you hear a warning siren immediately check the news for instructions.

The safest areas to visit are in central and southern Contra Costa County.
