AC Transit (local bus) is Free!
All Summer Sessions students will receive an Easy Pass for AC Transit, providing unlimited use all summer long. AC Transit is the bus system serving Alameda and Contra Costa counties (Berkeley is in Alameda county), with some service to San Francisco. Visit their website for route information. Your Easy Pass also doubles as a Clipper Card that you can load money on to use BART and other transit networks in the Bay Area.
