RMS Queen Mary in Southern California
Once the biggest and fastest ship that defined luxury in the late 1930s, the Queen Mary is now a Long Beach icon as a floating hotel and museum. It played a significant role for troops during World War II before reverting back to a cruise for the upper-class. The Queen Mary is supposedly one of the most haunted places with over 100 spirits known to occupy its quarters and 49 reported deaths over the last 60 years. You can stay aboard or take a paranormal tour at night to see any strange sightings for yourself.
