We combined the boat tour with a visit to the aquarium and it was great. The weather was absolutely great, plenty of sun and no fog. The panorama was really fantastic and the time (2:30 p.m.) was also very good. I can only recommend it. The photos were sensational. Yes, the boat was very full, but it was a lot of fun. We were at the top and so you could really see a lot. Highly recommended. We did the tour in conjunction with the City Pass and everything worked wonderfully. When we drove through the bridge, you suddenly felt very small. The back of Alcatraz is also well worth seeing, as you couldn't see it on the drive to Alcatraz, very nice bay tour.
