Our tour guide Roman was excellent! He provided top quality care and service, describing the rich and interesting history of San Francisco coupled with an excellent sense of humour! I really felt like I have been able to see the best that San Francisco has to offer, and all in one day, from the iconic Golden gate bridge, through ro the majestic redwoods and of course the famous Alcatraz! I would highly recommend this to singles, couples and families. If you have to pick one tour - do this one.
