this is one of my favorite haunts of all time. Knotts 40th haunt had much to be afraid of and there is a scare at every corner...LITERALLY. Every year there is much more to fear.
Knott's Halloween Haunt
Until Sat Nov 2 2013
Time Out says
Also known as Knott's Scary Farm, the Halloween Haunt goes all out with more than 1,000 monsters roaming ten mazes, five "scare zones" and six live shows. It's one of the largest (and oldest) Halloween events held at a theme park. If you don't think you'll last long enough to hit every single attraction, may we suggest Uncle Willy's Slaughterhouse maze (can you guess what kind of meat he serves at his BBQ?) and Delerium, which is essentially just a cacophony of screams and deeply disturbing nightmare visions.
