Items not allowed in the park include radios, stereos, luggage, and large coolers (Larger than 1'x1'x1'). Wagons used as strollers are allowed. All guests, bags, parcels and other items are subject to inspection, including metal detection or other screening measures.

Yes, Knott's Berry Farm has a comprehensive security screening process at the entrance that includes mandatory bag checks. In 2026, the park uses a combination of manual inspections and advanced metal detectors or "Evolv" AI scanners to ensure guest safety. For standard park entry, bags must be no larger than 15" x 15" x 15" (though some policies allow up to 16" x 24" x 8" for larger family totes). It is important to note that during Knott's Scary Farm (the annual Halloween event), the policy becomes much stricter: only clear plastic bags smaller than 12” x 12” x 6” are permitted, and small wristlets must be under 5” x 8” x 2”. Prohibited items that will be confiscated during the bag check include weapons of any kind, alcohol, glass containers (except for baby food), and large coolers. To speed up the process, security recommends having all pockets unzipped and removing large metal objects from your pockets before reaching the scanners.
