Right after Covid, my friends and I got Knott's annual passes because they were so cheap. We planned a visit, stayed at the Knott's hotel, and had a fun afternoon tea. I hadn't been there since I was pretty young so I didn't have many expectations. I really liked the Old West part of the park. Not to make fun, but the "mine train" ride was so Mickey Mouse, if you'll pardon the expression, that I laughed. The lines took forever (there's a way to do some kind of fast-pass thing but we didn't do that) and the rides were either carnival thrill rides or rather rinky when you're used to DLR.
I know they have good entertainment, but I'm not interested in going back. I come down from Northern California and I'd rather have another day at DL, visit the beach, etc than go to Knott's. I think it's a nice local's park but the vibe is very different from DLR and not as senior-friendly as DL. It's a great place if you're interested in thrill rides and more of a carnival vibe.
Every Disney fan should visit KBF at least once. There is a
Disney+ show where Imagineers and Disney historians discuss the heavy influence KBF had on Walt Disney and thus Disneyland and later Disney parks. In fact, they probably would not exist today had it not been for KBF. KBF was a successful theme park, but built in pieces as the idea evolved & to minimize risk. Walt Disney was a frequent visitor, especially during the creation of Disneyland, and would not have taken the financial risk of the park had KBF not convinced him it would be successful.
Walt rode the Clieco Mine Train quite frequently, and elements were brought into future DL attractions - especially the themed queues. Describe the ride as “Mickey Mouse” is so perfect

. The lead imagineers for Splash Mountain acknowledge that they rode Timberland Mountain Log Ride repeatedly during Splash Mountain’s design, and that Splash Mountain was basically a Disney version of the ride.
Most of the rides are thrill, since that’s what brings in crowds these days (there are several of them unique/ rare), but there are plenty of non-thrill rides including one of the oldest carrousels in the country, one of the oldest trains in operation and KBF’s version of the tea cups. Two of these rides were completely restored last year when Fiesta Village was overhauled. And Camp Snoopy completed its overhaul this year. Most small children will have more fun here than in DL. Plenty of fun for the family.
While locals dominate DL and KBF, I’d hardly describe either as locals parks. Nearby Adventure City, yes, KFB, no. If you choose to spend an off-day at DLR rather than Merry Farms (even if you skip the rides), you’re missing out!
Of course, there’s plenty of things to see and do in Los Angeles I’d recommend over DLR and KBF any day, but this is fourm where people make their first trip across the county to entirely stay within DLR
