Knott’s Halloween Haunt Celebrates 40 Years of HorrorKnott’s Scary Farm’s Halloween Haunt celebrates its 40th year of spooking guests. What originally began with a few Halloween decorations and costumed employees has grown to be the world’s largest Halloween event. Starting September 21 and running for 25 horrifying nights, the typically family-friendly theme park transforms itself into 160 acres of sheer terror complete with 12 mazes, six hair-raising shows, four horrific scare zones and 1,000 monsters roaming throughout the park. This year’s themed attractions include Terror of London, Dia de los Muertos and Uncle Willy’s Slaughterhouse. For a friendlier celebration, visit “Snoopy’s Costume Party.” This daytime, non-scare celebration is the social event of the season with shows, activities and trick-or-treating. Be sure to catch the PEANUTS Halloween “Spooktacular” in the Camp Snoopy Theatre. 8039 Beach Blvd., Buena Park, 714.220.5200. knotts.com
