The park said increasing incidents of “unruly and inappropriate behavior” over the last few years led to the new policy, which matches policies at other entertainment venues.
Knott’s Berry Farm in Buena Park, owned by the same company, adopted a similar policy in 2022 over an increasing number of fights during the summer.
Under the new rules, underage visitors between 4 p.m. and closing time must be accompanied by someone 21 or older.
The chaperone must show proof of his or her age, can accompany up to 10 guests, and must stay in the park and be reachable by phone while the guests are there. The policy applies to one-day visitors and season pass holders, according to the Six Flags website.
Guests 16 and older must also show proof of age under the new rules.
“We believe these changes will help ensure that Six Flags Magic Mountain continues to have a positive atmosphere where thrill-seekers can gather for a day of safe, fun, and thrilling experiences,” Six Flags said in a statement.
The park said guests caught line cutting, using profanity, or displaying other such unruly behavior are subject to ejection without a refund. Hand gestures, symbols, and abusive language all count as profanity, the park said.
Guests who leave their spot in line must return to the back of the line, even if they previously were ahead, and are not allowed to save spots for others, according to company policy.
Also, beginning Sept. 7, Six Flags and its adjacent water park, Hurricane Harbor Los Angeles, are implementing a smoke-free policy, which includes cigarettes, e-cigarettes, and marijuana. There will be a designated smoking area outside the parks for tobacco products only.
