A fantastic couple of hours in San Francisco. After a 10 minute ferry crossing, we arrived on Alcatraz Island, had a short introductory talk then walked upto the cell house. The 45 minute audio tour is very interesting & harrowing & it is fascinating to look around the cells & grounds of the world famous prison. There are beautiful views of San Francisco bay & the Golden Gate Bridge outside the cell house.
Book online in plenty of advance, as tickets sell out early. It is possible to buy tickets on the day, but this involves queuing up very early, with no guarantee of getting a ticket.
