This October, Knott's Berry Farm has transformed itself into a living horror movie that's not for the faint of heart. Just in time for Halloween, snag tickets to see "Knott's Scary Farm's 40th Haunt" for $33.

This three-day sale saves visitors $27 on tickets purchased at the gate and offers a steeper discount than all other online presales. This deal is valid for one-night admission on Thursday and Sunday evenings through Oct. 28.

The 160-acre haunted theme park includes 13 terrifying mazes, nine hair-raising shows, four "scare zones" and more than 1,000 monsters roaming the park to seek out their next victims. Knott's Berry Farm closes and ceases regular operations at 5:30 p.m. and reopens from 7 p.m. to 1 a.m. for this Halloween event.
