14. Warm Springs Canyon Road
Located in sunny Death Valley (that should tip you off), the 16-mile Warm Springs Canyon Road leads to a place called Barker Ranch, which was home to the infamous Manson Family in the late 1960s. Fire destroyed it in 2009, and hikers are allowed to camp on the site. Travel Channel says some hikers reported “hearing screams, the feeling of being watched, and smelling decomposing bodies.” ‘Nuff said.
15. Violet City Lantern Tour and Heritage Walk, Mammoth Cave, Kentucky
Apparently this part of the huge cave complex was once used as a hospital for tuberculosis patients in the 1800s. A fellow named Dr. John Croghan believed that the cave had healing powers, so he built 11 huts within them. Several patients died there (imagine that) and the good doctor gave up his experiments.
A few of those huts remain, as does Corpse Rock, where bodies were temporarily housed. Some visitors report hearing… coughing. I went to Mammoth Cave way back in the day—if someone had mentioned all this, I would’ve stayed in the car.
