California has many really scary haunted locations, ghost tours, real haunted houses and much more to explore throughout the state.  Starting with one of the most haunted places in California,  Alcatraz was the ultimate American prison.  From the time it became a federal prison in 1934 until it was closed down in 1963, the steel doors clanged shut behind more than 1,000 hardened convicts, criminals and escape artists.  


Every visitor who arrives by boat on Alcatraz follows the same path once walked by the criminals who came to do time on the Rock. The tourists who come here pass through the warden’s office and the visiting room and eventually enter the cell house.  It has been reported of steel chains being heard in the utility corridor.  There have also been reports of "men running" and getting a strange feeling when walking into certain areas. 


As the years have passed, ghost hunters, authors, crime buffs and curiosity-seekers have visited the island and many of them have left with feelings of strangeness.  It has been said that the walls of Alcatraz turned many men crazy or insane.  The story goes that in his last days at the prison Al Capone would hide in the showers and play his banjo.  It has been reported of hearing a banjo playing near the showers.
