Buena Park theme park Knott’s Berry Farm on Saturday opened a special museum dedicated to this year’s 40th Halloween Haunt.

A ribbon cutting ceremony for the museum was held Friday.

Knott’s is part of Sandusky, Ohio-based amusement park operator Cedar Fair Entertainment Co.

Halloween Haunt is a major draw as a seasonal event at Knott’s, with the park redecorated at night with mazes, themed shows and employees dressed as monsters. The event is scheduled for a 25-night run this year between Sept. 21 and Oct. 31.

The museum, which is located in the Calico Ghost Town section of the park, offers guests video footage, costumes and other memorabilia from past Haunts.

A separate, Halloween-themed attraction for kids, called Snoopy’s Costume Party, runs during the day, offering shows, craft stations and trick-or-treating.

Ticket prices for the Haunt start at $36. Haunt admission plus a meal starts at $50.99.

Knott’s charges $36 for general admission online and $58 at the gate.

Elsewhere in the park, Knott’s Perilous Plunge rollercoaster ride, located in the park’s Boardwalk-themed area, closed for good on Monday. Knott’s said it will disassemble and remove the ride, and has not yet indicated its plans on what to put in its place.
