Fort Stevens State Park is described as a reportedly haunted location where visitors and investigators have experienced unexplained sounds, cold spots, and feelings of being watched, attributed to lingering spirits of former soldiers or workers. Reports include hearing footsteps, distant voices, and seeing figures, particularly in the old gun batteries and underground areas, with the campground also being a site for ghost stories. Visitors have reported hearing disembodied whispers, voices, footsteps, distant laughter, and even faint wailing or shouting. Some claim to have seen a man in a military uniform or a ghostly figure walking between trees. A common experience is a sudden drop in temperature, a heavy feeling in the air, or unexplained moving objects and unzipped tents. A pervasive sense of being watched is frequently reported by visitors and investigators, especially in more remote or underground sections of the fort. The old gun batteries, particularly Battery Pratt and other underground rooms, are central to many of the haunting experiences. The park's popular campground is also a hotspot for paranormal activity, with campers reporting sounds and sightings of spectral figures.
