Beardslee Castle in Little Falls, NY, is known for paranormal activity, including apparitions of a bride in white, disembodied voices, footsteps, and unexplained smells. Visitors and staff have reported flickering lights, doors opening on their own, and moving objects like chairs and napkins. These experiences are attributed to various historical figures, including Augustus Beardslee himself, a bride who died before her wedding, and Native American spirits connected to the site's past. A "woman in white," possibly a bride named Abigail who died before her wedding, is said to appear in the halls. There are also reports of a man holding a lantern, thought to be the ghost of Augustus Beardslee, and figures vanishing into the woods. People report hearing disembodied voices, a woman singing, and a lullaby echoing through the castle. Guests and staff have witnessed chairs moving, airborne napkins, and bottles flying around the bar. A strong perfume scent has been detected in empty rooms, particularly the carriage house. Some report sensing the presence of Native American spirits on the grounds.
