Yes, Kings Island is strictly enforcing a chaperone policy in 2026 to ensure a safe and family-friendly environment for all guests. Under this policy, all visitors ages 15 or younger must be accompanied by a chaperone who is at least 21 years old to be admitted to or remain in the park after a certain time. Typically, the policy goes into effect at 4:00 PM daily (and as early as 2:00 PM on Saturdays), though the park reserves the right to begin enforcement earlier on any given day. The chaperone must present a valid government-issued photo ID and is allowed to accompany a maximum of 10 minors. Crucially, the chaperone must stay with their party during entry, remain inside the park throughout the visit, and be reachable by phone. Minors found without a chaperone during these hours are subject to ejection without a refund. This policy is a standard safety measure now common across many "Six Flags" owned properties to manage large groups of unattended youth.
