We were in Cadiz on a Sunday, so a lot was closed down. I think that the group was too large for a walking tour, as well as there was a lot of intereference with our audio's so very difficult to hear what our guide had to say. She was very nice and seemed to be very knowledgeable on the subject of Cadiz, but honestly if you are going to walk it (very easy), as both the town and the Hop On / Hop Off buses are located directly at the port, then I would just go on my own. This port didn't rank very high with me.
