Today, by Pier 33 where passengers wait to take the Alcatraz ferry is a huge model of the island.
There is plenty of room indoors, but most people prefer to be on the upper decks with no windows to hamper the view of the scenery.
There are some night tours and even overnight tours of Alcatraz, but I prefer day tours just in case these ghosts are real. :D
The menu you see at the top is the last meal served here.
