Kids Ride Free on BART

San Francisco Bay Area Rapid Transit is offering free rides for children 12 and under on Saturdays in August. Each fare-paying adult may be accompanied by up to two children. Each child must have a Flash Pass to show the station agent. (click here for PDF Flash Pass). Use the swing gate instead of the regular fare gate.
