Colorado: The Stanley Hotel, Estes Park - No haunted hotel is more famous than The Stanley, the inspiration for Stephen King's classic horror novel The Shining. Some rooms are said to get more supernatural visitors than others, most notably Room 217, where King himself stayed. Among the rumored spirits are the Stanleys, the previous owners of the famed hotel, and Elizabeth Wilson, a chambermaid who was electrocuted here and later died. The hotel embraces its eerie reputation and whisks guests on creepy expeditions like The Stanley Hotel Spirited Night Tour. Have you ever stayed at this hotel?

Connecticut: The Mark Twain House, Hartford - "A house with a heart and a soul" – that's how the home of late writer Mark Twain, or Samuel Clemens, is described. Rumor has it, it's also a house with a ghost or two. Twain lived in the High Gothic Hartford home between 1874 and 1891, and some think he never left. Visitors have reported the smell of his scent wafting through the halls, plus other mysterious specters including the ghostly image of a woman in white. Have you ever visited this house?

Delaware: Amstel House, New Castle - Only a small handful of early colonial buildings remain in the city of New Castle, and among them is Amstel House, which dates to the 1730s. Spirits and specters wouldn't look out of place in this red-brick Georgian mansion, with its elaborate central entryway and period finishes. And several unknown ghosts are said to walk between these walls. Some say one is the spirit of Anna Dorothea, daughter of the home's former owner Dr John Finney. Have you ever visited this house?

Florida: Deering Estate, Miami - Centuries-old mansions are perfect fodder for ghost stories – and the Deering Estate, former home of industrialist Charles Deering, apparently has a whole roster of eerie residents. The 1920s-era property remained in the Deering family for decades and, in more recent years, ghost-hunting teams have made recordings of supernatural voices echoing about the place. Now ghost tours take curious visitors on their own hunt for the paranormal. Have you ever visited this house?

Georgia: The Pirates' House, Savannah - The city of Savannah is as haunted as they come, with inns, restaurants and cemeteries all claiming to harbor supernatural beings. Few places are more likely to make your hair stand on end than The Pirates' House, though. The restaurant and tavern is often tipped as the oldest building in Georgia (dating right back to the 1750s), so it's little surprise that it has a long history of hauntings too. Staff tell tales of ghostly sailors floating between tables, their moans echoing up from tunnels below. Have you ever visited this house?
