Knott's Scary Farm, Halloween Horror Nights, Fright Fest, Dark Harbor, Halloween Time
Below is a list of Halloween Theme Park Attractions in Los Angeles and the surrounding area. These are the big guns of the Halloween season: year-round entertainment centers like Disneyland, Knott's Berry Farm, Universal Studios Hollywood, and Six Flags Magic Mountain that put on special Halloween haunts during October. Typically, these offer multiple seasonal attractions, including haunted houses, mazes, scare zones, and show, with their year-round rides and attractions redressed for Halloween. Not all of them are located in Los Angeles, but all of them are easily accessible by freeway.
In order to distinguish between these elaborate Halloween theme parks and smaller scale seasonal events that take place in major tourist venues (such as the Los Angeles Zoo and the Aquarium of the Pacific), here we include attractions that provide a full night (or day)'s worth of Halloween entertainment, not merely a sideshow on top of their usual attractions. Each of these attractions is listed on its own webpage.
Los Angeles Halloween Theme Parks: Comparison
Which is the king of Los Angeles Halloween Theme Parks? The answer varies from one year to the next, but each venue has consistent strengths and characteristics. Disneyland's Halloween Time and Legoland's Brick-or-Treat are appropriate for younger Halloween fans. If you are seeking real scares, the Knotts Berry Farm Halloween Haunt is the longest-running and the largest event; Halloween Horror Nights at Universal Studios Hollywood is the most elaborate haunted theme park attraction. Queen Mary Dark Harbor makes good use of its unique setting, an actual ship with ominous dark corridors. The Six Flags Magic Mountain Fright Fest has the best roller-coasters, and some of its mazes now rival the best in the South Land.
