Enjoy the Golden Gate and take in the sights from the Bay as you travel to or from San Francisco. Ferry routes provide daily service (except New Year's, Thanksgiving, and Christmas days) between Sausalito or Larkspur in Marin County and San Francisco, at varying intervals of 15 to 120 minutes, depending on the time of the day, day of the week, and season.
