On the Rock
The rock was eerie. The stories told during the audio tour, ghosts of years past. Definitely worth the visit.
As a random side note. Alcatraz is a national park now. A federally protected bird sanctuary. Knowing this I was quite eager to keep my eyes peeled for some fancy feathered friends. And I saw some. The protected grey tipped seagull. Umm yeah not exactly what I was expecting.
