Took a tour of downtown San Francisco on board the City Sightseeing double decker bus. One of several bus companies, but we chose City Sightseeing due to one of their stops being only a 30 minute walk from the Caltrain station. The guides were very knowledgeable and entertaining at the same time. It was a good way to orientate first timers with the city. Our next visit we will spend more time in the many localities “the City” has to offer.
