1. San Diego: Gaslamp Quarter Ghosts and Crime Walking Tour
Walk around San Diego's Gaslamp Quarter and get acquainted with the spookier side of town on this history-packed tour by US Ghost Adventures. This walking tour shows you around some of the best-known haunted locations on the West Coast. You’ll meet your guide by the Balboa Theatre, which has been a downtown fixture since the 1920s. You’ll head to eight spooky, haunted sites, including the infamous Davis-Horton House. Investigate a 50-year-old unsolved murder at Old City Hall. Find out what lies behind the front door of Eddie O’Hare's Law Office. Also, search for the eyeless ghost of a little boy at the Carriage Works. If you're up for it, end your tour with an optional sweet treat at the Ghirardelli Ice Cream and Chocolate Shop. This is much more than an ice cream shop. You can hear a former movie theater employee screaming for something other than ice cream.
