San Diego, with an oceanfront amusement park, beautiful beaches, and balmy weather year-round, might not be top of mind when you think of fall destinations – it has none of the classic fall foliage that some places in the U.S. have. But while it may lack traditional autumnal vibes, it’s still a fantastic Halloween vacation destination since it’s home to the Whaley House, which bills itself on its website as “America’s most haunted house.” Over the years, it has attracted all kinds of paranormal investigators hoping to get a glimpse of the house’s (in)famous long-time inhabitants.
