As far as quintessential ghost experiences go, haunted castles are the crown jewel. Hidden passageways, dungeons frozen in time, and eerie corridors are like catnip for those with a proclivity toward the paranormal. If you identify as a supernatural superfan, a pilgrimage to one of the most notorious royal hauntings around the world is best enjoyed in October, the spooky season. And even if you’re a spectral skeptic, the best castles purporting to be haunted also happen to be set in beautiful landscapes and offer centuries-worth of historical context. (A well-rounded experience, if you will.)
From the English countryside to the green hills of India, all of these ghostly destinations below are open to visitors, with some even offering the rare opportunity to stay overnight—if you dare.
