All alone in the Rocky Mountain West, Denver is one major U.S. city you definitely shouldn’t overlook in terms of paranormal activity. The Croke Patterson Mansion has about one of the most blood-chilling origin stories around and conjures up frights to this day even to the passerby. Across town, the Peabody-Whitehead means is just as equally terrifying in the many frights it beholds. The real-life Changeling House here spawned decades of terror and even a major Hollywood motion picture chronicling its many terrors. If you are more the haunted attraction type, HellScream Haunted House does it better than anyone else in the Rocky Mountains. Denver is definitely Miles High over any surrounding paranormal competition.
