You'll love Scary Farm! The whole park more or less becomes a scare zone.
Of the returning mazes that I've experienced (admittedly not a whole lot of them, I haven't been since 2019), Calico Origins was my favorite and Dark Entities the one least for me.
If you're willing to splurge a bit beyond admission, though pricey, the Fast/Fright Lane Combo is a big help at getting through the lines pretty quickly.
If that's not in the cards (it IS a ton of money per person), a more modestly priced upgrade that offers a huge advantage is the Boofet dinner. For about $50/person, you get dinner taken care of during the window that the park is closed and is transitioning to the event-a buffet of various traditional Knott's items and themed Halloween foods, while Scareactors are available for interactions or photos if desired. You get a good sampling of items without having to worry about wasting time eating during the event. After eating, you get a HUGE unadvertised perk-GhostRider opens about 30 minutes after the regular park operating day ends, and if you want to do this ride at all (one of my favorite coasters ever), THIS is the time-finish eating by about 6 or so, and you can have the ride almost to yourself for about 30 minutes-even with Fastlane during Haunt (or during regular park hours on a weekday, when the park is otherwise slow) the GhostRider line is VERY slow and you will waste a fair amount of time trying to do it (well over an hour if you try and do it during Scary Farm WITHOUT Fastlane at the very least). Then at about 6:30, they'll open up the four mazes closest to Ghostrider (Waxworks, Depths, Dark Entities, and a newer one that I haven't experienced). That will allow you to do four mazes before the rest of the park opens. Time it right, and you can watch the opening moment where the scareactors LUNGE at the entering crowd!
But no matter what, it's a fantastic event! So excited to be going back!
