We didn't have the pleasure of doing a guided tour, but even without it this place was just amazing. I wasn't terribly interested in the history, loved Shawshank but haven't seen it for years so didn't really recognize anything, and am not really into the paranormal (I was looking for ghosts... I guess they had no interest in me that day). Despite all that, this was one of the coolest places I've ever been... especially in North America. Would totally go back again and do a tour, though definitely won't be the same jaw-dropping experience when entering the east cell block.
In past years the station would open to the public once a year for the "Open Doors" festival, however it was excluded from the 2014 list of venues. The infamous subway station fight scene from The Matrix was filmed here.
