Alcatraz is special because it is where stories of American incarceration, justice, and common humanity can be found. Famous for being a prison, but in actuality so much more.
Alcatraz is located on an island, called Alcatraz Island off the coast of California. You have to pay and you have to get a ticket for one of the round trip ferry trips and an audio tour.
There is many things to see as your audio tours would most likely tell you. When you arrive, there is an orientation to explain what things to do on the island. The audio tour covers the inside of the cellhouse from 1934 to 1963.
