I will be visiting the San Francisco area in a few weeks, I will be doing a 9am Alcatraz tour on a friday. From the little research I have done so far, a good place to park is the Imperial Parking Lot at 2210 Stockton Street if I arrive by 9am. I also found another lot at 350 Beach Street with a early bird rate. I don't mind walking to Pier 33 from any of these lots.
Can anyone confirm that these parking lots are really a good bargain?
