Golden Gate Transit (GGT) is a public transportation system serving the North Bay region of the San Francisco Bay Area in California, United States. It primarily serves Marin County, Sonoma County, and San Francisco, and also provides limited service to Contra Costa County. In 2021, Golden Gate Transit had a ridership of 814,200, or about per weekday as of the third quarter of 2022.
Golden Gate Transit is one of three transportation systems owned and operated by the Golden Gate Bridge, Highway and Transportation District; the others are the Golden Gate Bridge and Golden Gate Ferry, both of which connect San Francisco and Marin County. Funding for cross-bridge "Transbay" bus service is partially subsidized by Golden Gate Bridge tolls in addition to traditional federal and state sources.  GGT operates some bus service within Marin County under contract with Marin Transit.
Golden Gate Transit service began on January 1, 1972, as the culmination of years of work for the Golden Gate Bridge to alleviate traffic congestion, reduce pollution, and take over unprofitable commuter bus service operated by Greyhound.  GGT had previously began operating local bus service in Marin County under contract with Marin Transit beginning December 15, 1971.  Initial service ran on two corridors in San Francisco: Civic Center routes on Van Ness Avenue and the McAllister/Golden Gate one way pair, and Financial District routes on North Point Street and the Battery/Sansome pair. 
The system initially operated with 152 buses, including 20 leased buses, out of garages in Novato and Santa Rosa and a temporary facility in San Rafael. A permanent garage opened in San Rafael in 1974, and the facility was expanded in 1987 to house additional administrative staff. Transbay commuter bus service was reduced in 1987 as a result of declining ridership associated with a shift in jobs from San Francisco to Bay Area suburbs. However, that increase in the number of suburban jobs led to the initiation of commuter bus service from Sonoma County to Marin County employment centers in 1990.
In 1992, the District and opened the C. Paul Bettini Transit Center in San Rafael (also called the San Rafael Transit Center). The transit station was designed as the hub in a hub-and-spoke local bus system and immediately became GGT's busiest transit station. In 1993, acting on behalf of MTC, GGT began operating service between Marin and Contra Costa counties via the Richmond-San Rafael Bridge. That same year, the district initiated inter-county paratransit service, as required by the Americans with Disabilities Act), through an agreement with Marin County and its paratransit contractor, Whistlestop Wheels.
Significant service reductions were implemented in 2003 as a result of a declared fiscal emergency. As a result of the restructuring, all GGT service to the Sonoma Valley and Sebastopol was eliminated. Ferry Feeder bus routes to the ferry terminals in Larkspur and Sausalito were also discontinued. This fiscal emergency helped spur the passage of Measure A by Marin County voters in 2004. The sales tax measure established a new funding source for Marin Transit and was a catalyst for changes to the contract the District had with Marin Transit. Marin Transit assumed control over local bus service planning, and it began transitioning some service to private contractors.
On June 15, 2009, Golden Gate Transit began operating Route 101,  which provides all-day service between Santa Rosa and San Francisco with fewer stops, similar to many bus rapid transit "light" systems that rely on stop spacing changes rather than capital improvements to speed up buses. Introduced initially as a weekday-only route, service was expanded to Saturdays in June 2010 and to Sundays and holidays in September 2011.
On December 13, 2015, service to Contra Costa County on Route 42 was merged with Route 40. The next day, service began on Route 580,  which was the District's first transit line into nearby Alameda County. The latter experiment failed and Route 580 was discontinued in September 2016, however the numeric designation was revived when Route 40 was renumbered to Route 580 in December 2021. GGT buses returned to Alameda County in February 2019 to provide Early Bird Express bus service under contract with BART.
As a result of declining ridership due to the COVID-19 pandemic and the resulting loss in operating revenue, including a reduction in Golden Gate Bridge tolls,  bus service was dramatically reduced throughout 2020. GGT had 27 routes at the beginning of the pandemic and just seven routes by December 2020. In March 2022, Route 4C was revived as Route 114.
Golden Gate Transit serves cities and communities in four Bay Area counties: San Francisco, Marin, Sonoma, and Contra Costa.

Golden Gate Transit charges different fares, depending on distance (zones) traveled and method of payment.  Fares can be paid with cash or Clipper card. As of July 1, 2021, adult cash fares are as follows:
|San Francisco||Marin County||Sonoma County||East Bay|
Adult Clipper fares are discounted 20% for most trips, except within Zones 2, 3, and 4 where the discount is 10% to match Marin Transit fares. A 50% discount is provided to youth (ages 5 through 18), senior (ages 65 and over), disabled ( ), Medicare passengers, and passengers with a Clipper START card. In addition, as a result of a bus service contract with BART, Clipper fares for travel within Zone 7 and between Zones 1 and 7 are further reduced.
Transfers are issued by the farebox upon request at the time of cash fare payment. Clipper automatically tracks transfers.  Transfers are valid for two hours for intra-county travel and three hours for inter-county travel and can be used twice. Round-trips are not permitted for inter-county travel. Full transfer privileges are available to/from Marin Transit.
Transfers are issued from GGT to Golden Gate Ferry for cash and Clipper customers, but transfers from Golden Gate Ferry to GGT are available only to Clipper customers. Transfers are available to/from some other connecting transit systems, including AC Transit, Muni, Petaluma Transit, Santa Rosa CityBus, SMART, SolTrans, Sonoma County Transit, and WestCAT. Muni transfers are available only to Clipper customers.
Golden Gate Transit accepts one-day and 31-day passes issued by Marin Transit for rides within Marin County. No other pass products are accepted.
The Club Bus program was administered by Golden Gate Transit through 2012. It provided commuter clubs with contract support for subscription bus service on routes not otherwise operated. The program also provided a 30% subsidy for the cost of service.  The program required the formation of not-for-profit organizations to collect riders' subscription fees and develop schedules.
The Marin Commute Club, which began service in 1971, had direct service from Marin County to three University of California, San Francisco locations (Parnassus Campus, Mission Bay Campus, San Francisco General Hospital) not otherwise served by Golden Gate Transit. Daily ridership dropped from 300 in 1978 to 120 in 2012, and down further to 55 in 2014 shortly before the service was discontinued altogether.  
The Valley of the Moon Commute Club provided bus service to the San Francisco Financial District from the Sonoma Valley, which otherwise does not have direct bus service to San Francisco. It was created in 1973 and operated as part of the Club Bus program until 2011.   At its peak, the club had service on five buses. However, the economic downturn and changing travel patterns resulted in substantial service reductions and fare hikes. By late 2010, service had been cut to one round-trip with a monthly subscription fee of $350.  In February 2011, with the club on the brink of shutting down, service was transferred to a private tour company.  Due to further ridership declines, service was discontinued in May 2014. 
Bay Area Rapid Transit (BART) is a rapid transit system serving the San Francisco Bay Area in California. BART serves 50 stations along six routes and 131 miles of track, including a 9-mile (14 km) spur line running to Antioch, which uses diesel multiple-unit vehicles, and a 3-mile (4.8 km) automated guideway transit line serving the Oakland International Airport. With an average of 145,700 weekday passengers as of the third quarter of 2022 and 26,026,800 annual passengers in 2021, BART is the fifth-busiest heavy rail rapid transit system in the United States.
AC Transit is an Oakland-based public transit agency serving the western portions of Alameda and Contra Costa counties in the East Bay of the San Francisco Bay Area. AC Transit also operates "Transbay" routes across San Francisco Bay to San Francisco and selected areas in San Mateo and Santa Clara counties. AC Transit is constituted as a special district under California law. It is governed by seven elected members. It is not a part of or under the control of Alameda or Contra Costa counties or any local jurisdictions.
Wheels is a bus service that provides public transportation in the Tri-Valley Region of the San Francisco Bay Area, in the United States. Started in 1986, Wheels offers service to various communities in three cities, and connects to Bay Area Rapid Transit (BART) and Altamont Corridor Express (ACE) trains for connections to and from the greater Bay Area and Central Valley. In 2021, the system had a ridership of 635,600, or about 3,600 per weekday as of the third quarter of 2022.
SamTrans is a public transport agency in and around San Mateo, California, in the San Francisco Bay Area. It provides bus service throughout San Mateo County and into portions of San Francisco and Palo Alto. SamTrans also operates commuter shuttles to BART stations and community shuttles. Service is largely concentrated on the east side of the Santa Cruz Mountains, and, in the central county, I-280, leaving coast-side service south of Pacifica spotty and intermittent.
The North Bay is a subregion of the San Francisco Bay Area, in California, United States. The largest city is Santa Rosa, which is the fifth-largest city in the Bay Area. It is the location of the Napa and Sonoma wine regions, and is the least populous and least urbanized part of the Bay Area. It consists of Marin, Napa, Solano and Sonoma counties.
Intermodal passenger transport, also called mixed-mode commuting, involves using two or more modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths of various transportation options. A major goal of modern intermodal passenger transport is to reduce dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey.
The Clipper card is a reloadable contactless smart card used for automated fare collection in the San Francisco Bay Area. First introduced as TransLink in 2002 by the Metropolitan Transportation Commission (MTC) as a pilot program, it was rebranded in its current form on June 16, 2010. Like other transit smart cards such as the Oyster card, the Clipper card is a credit card-sized stored-value card capable of holding both cash value and transit passes for the participating transit agencies. In addition to the traditional plastic card, Clipper is available as a virtual card in Google Wallet and Apple Wallet. Clipper is accepted by nearly all public transit services in the Bay Area, including but not limited to Muni, BART, Caltrain, AC Transit, SamTrans, Golden Gate Transit, Golden Gate Ferry, San Francisco Bay Ferry, and VTA.
Sonoma–Marin Area Rail Transit (SMART) is a rail line and bicycle-pedestrian pathway project in Sonoma and Marin counties of the U.S. state of California. When completed, the entire system will serve a 70-mile (110 km) corridor between Cloverdale in northern Sonoma County and Larkspur Landing in Marin County. In 2021, the system had a ridership of 225,200, or about 1,800 per weekday as of the third quarter of 2022.
The Golden Gate Bridge, Highway and Transportation District is a special-purpose district that owns and operates three regional transportation assets in the San Francisco Bay Area: the iconic Golden Gate Bridge, the Golden Gate Ferry system and the Golden Gate Transit system. All three assets connect Marin County with San Francisco.
People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, eight passenger rail networks, eight trans-bay bridges, transbay ferry service, local and transbay bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
The All Nighter is a night bus service network in the San Francisco Bay Area, California. Portions of the service shadow the rapid transit and commuter rail services of BART and Caltrain, which are the major rail services between San Francisco, the East Bay, the Peninsula, and San Jose. Neither BART nor Caltrain operate owl service due to overnight track maintenance; the All Nighter network helps fill in this service gap. The slogan is, "Now transit stays up as late as you do!"
San Francisco Bay in California has been served by ferries of all types for over 150 years. John Reed established a sailboat ferry service in 1826. Although the construction of the Golden Gate Bridge and the San Francisco–Oakland Bay Bridge led to the decline in the importance of most ferries, some are still in use today for both commuters and tourists.
Sonoma County Transit is a public transportation system based in Sonoma County, California.
Marin Transit is a public bus agency in Marin County, California, in the United States. Originally formed in 1964 as Marin County Transit District (MCTD).
