The ghosts that haunt Massachusetts don't always confine themselves to buildings, according to paranormal investigators. Some prefer to wander our forests, swamps and other dark wildernesses still untamed by humans.

The locations listed below all have one thing in common -- a violent and tragic past. Paranormal investigators believe their morbid histories have led them to become hotspots for the supernatural.

It is in these haunted places most-of-all that visitors seeking out an encounter with the paranormal should use caution and be respectful. Entering a restricted area or following the wrong light go could land you at the bottom of a black pond or in front of a train going full-speed ahead.
