Awesome bridge bike tour and our guide was fantastic!.Doing the afternoon tour meant that the fog was able to lift - it was amazing to cycle over the bridge. The free ferry ride back was an added bonus.
The tour guide was not particularly friendly but very knowledgeable throughout the city tour. Alcatraz was great. The audio guide was very easy to follow and the cruise ship staff very good at organising large numbers of people. Definitely recommend but book early as trips to Alcatraz were booked out for a week.
