The Stanley Hotel
Located in Estes Park, Colorado and the inspiration for Stephen King's "The Shining". The hotel opened in 1909 as a resort for upper-class Easterners and as a health retreat for sufferers of pulmonary tuberculosis.
The ghost of Freelan Oscar Stanley (who suffered from tuberculosis), has been seen in the billiard room. His wife, Flora, has been heard playing the piano. The ghost of housekeeper Elizabeth Wilson haunts room 217 (the bathroom ghost). There are reports of shadowy figures, apparitions of children, and ghostly cats and dogs from the hotel's pet cemetery.
