Yes, Kings Island strictly enforces a Chaperone Policy in 2026 to ensure a safe and family-friendly environment. Under this policy, all guests aged 15 years old or younger must be accompanied by a chaperone who is at least 21 years old to be admitted to or remain in the park. This policy is typically in effect daily starting at 4:00 PM, though on Saturdays it often begins earlier at 2:00 PM. The chaperone must present a valid government-issued photo ID and must remain inside the park with their party for the duration of the visit. One chaperone can accompany up to 10 minors. In 2026, security teams frequently check IDs at the gate and throughout the midways; any minor found unaccompanied after the policy start time is subject to ejection from the park without a refund, making it essential for families to plan their afternoon and evening arrivals accordingly.
