The Oakland ferry to San Francisco is at the foot of Broadway at Jack London Square. It runs hourly and the trip takes about 30 minutes. Lots of folks commute to their SF jobs by ferry. There also are ferries to AT&T Park during baseball season and summer ferries to Angel Island. Before the bridges were built ferries were the only way to get to SF from the East and North bay. As our car culture grew, the ferries more or less became novelties and often faced extinction. After the big earthquake in 1989, the Oakland Bay Bridge was out of commission for a number of months and the use of ferries became essential and once again valued.
