Yes, Six Flags maintains a strict security screening process at all park entrances in 2026, which includes a manual or technological bag check. Upon arrival, all guests must pass through metal detectors, and any bags brought into the park are subject to inspection by park personnel. To streamline this, Six Flags has implemented a moderately strict bag policy: backpacks and bags larger than 12" x 12" x 6" are generally not permitted inside the park. Small clutches, fanny packs, and clear bags within these dimensions are allowed. Prohibited items that security looks for include weapons of any kind, self-defense devices like pepper spray, and outside food or beverages (except for specific medical or infant care needs). In 2026, many Six Flags locations have upgraded to "Evolv" or similar high-tech touchless scanners that can detect threats inside bags without a full manual search, but security guards still reserve the right to perform a "physical dig" if the scanner flags an anomaly or if the bag is opaque.
