并没有直接从旧金山机场到UCSC的，你需要转很多次车。。。我从UCSC官网上找到的，教怎么从机场到学校SFO Airport Ground TransportationSan Francisco Airport (SFO) is approximately 62 miles from the UC Santa Cruz campus. Catch a BART train at the SFO International Terminal; the SFO BART Station is located on the Departures/Ticketing Level of the International Terminal (Boarding Area G side). BART is easily accessed from any terminal by riding SFO's free AirTrain to the Garage G/BART Station stop. BART provides a direct connection to Caltrain at the Millbrae station. Ride Caltrain from the Millbrae station to the San Jose Diridon (Cahill Street) station. At the San Jose Diridon station transfer to the Highway 17 Express bus to Santa Cruz Metro's Pacific station in downtown Santa Cruz. Take any University Route bus from Santa Cruz Metro's Pacific station to the UC Santa Cruz campus.机场内有Bart，就是旧金山湾区的地铁，坐这个的时候一定要注意不要坐错方向了，Millbrae离机场没几站路，大概1-2站吧，是个终点站。下来以后做Caltrain（火车）到San Jose Diridon station，Cahill路，接着换坐高速17的公交车到Santa Cruz中心地带，然后坐学校的公交车到学校就好了。
