Mountain View is one of the major cities that make up Silicon Valley, and has many notable Silicon Valley companies either headquartered there or with a large presence, including Google, Symantec, Nokia and Microsoft.
Mountain View is reachable from all three Bay Area airports:
San Francisco: Take a short ride on the BART train to Millbrae station, then take Caltrain southbound service.
San Jose: Take a free shuttle to Caltrain's Santa Clara station and then take the northbound train service. Also, you can take a free shuttle to the VTA Metro/Airport station and take the VTA light rail.
Oakland: Take a shuttle van service. This is the least desirable of the three airports in terms of distance. You can also take a shuttle to the Coliseum/Oakland Airport BART station, take BART to Millbrae station, then take Caltrain southbound.
Caltrain service connects Mountain View to San Francisco and San Jose. There are two stops. Most trains stop at downtown (Castro St) stop.
It is possible to connect to Amtrak trains via San Jose Diridon station via Caltrain.
There is also a VTA light rail service that connects downtown to several suburb locations in the south bay. VTA light rail can also be used to connect to the Amtrak Capitol Corridor train (to Sacramento) in Santa Clara.
For travel within Mountain View itself and the neighboring area, The Santa Clara Valley Transportation Authority  (VTA) operates bus and light rail service. The Caltrain , which runs all the way from San Francisco to Gilroy stops in Mountain View as well. Caltrain also provides relatively easy access to both San Francisco and San Jose Airport.
