When my friends and family visit San Francisco, they always ask me what they should do besides visiting Alcatraz..... Well, for one I think Alcatraz is over-rated! My all time favorite is the San Francisco Duck Tours! I think it is the best way to see San Francisco. So far, I have not been wrong with my recommendations. All my friends and my family agree.... so for those of you who are visiting San Francisco and who are looking for something fun to do, I highly recommend the San Francisco Duck Tours -- it's an 80 min tour of the city by Land and by Water!
