Starline’s Haunted Hollywood Tour takes you through various spots in Hollywood that are believed to be haunted.
The Fullerton Haunted Walking Tours takes visitors to different parts of downtown Fullerton where they are treated to tidbits of local history and their related hauntings. I’ve actually been on this one a few years ago, and do recall walking mostly through the various shops and buildings that line Harbor Blvd, such as the Villa Del Sol and even to a few off-Harbor shops like Le Potager.
Queen Mary, Long Beach
It looks like this tour runs year-round.
Hosted by the crew at HauntedOC.com, similar to the Fullerton Haunted Walking Tour, visitors are taken around old town Orange (Also known as Orange Circle).
Another HauntedOC.com ‘joint’, visitors are shown around the histories and haunts of different buildings in downtown Santa Ana.
If there are any others in the Southern California area that aren’t listed here please let me know.
