I had gone on the early morning tour two years ago, so I looked forward to seeing Alcatraz at night. It was awesome. I definitely recommend booking a tour if you are ever in San Francisco. Tickets sell out weeks in advance, though; several people joined our tour after waiting in the "standby" area, but many were turned away. Here is a link to my pictures: https://www.facebook.com/media/set/?set=a.10102185687416994.1073741859.30311596&type=1&l=68134e1115 You do not need a Facebook account to view them. I don't have a fancy camera, so some of they may be a little blurry or grainy. These were all taken with my iPhone 6, in HDR mode, without a flash (except where noted - some of the hospital rooms didn't have lights on).
