Six Flags Entertainment reopened Six Flags Magic Mountain on Monday afternoon, May 11, after law enforcement officials cleared the park following a bomb threat that delayed operations for several hours.
Authorities told ABC 7 that the threat came in around 7:45 a.m., roughly three hours before the Southern California amusement park was scheduled to open to the public. The call prompted a large emergency response involving the Los Angeles County Sheriff's Department, the California Highway Patrol, and local firefighters, who conducted a sweep of the sprawling Valencia property before ultimately determining there was no active danger.
Aerial footage from local news outlets showed more than a dozen sheriff’s vehicles outside the park, along with emergency response units and an armored vehicle used during the search. Deputies completed their inspection by late morning and issued an “all clear” around 11 a.m. The park officially reopened at 12:30 p.m., several hours behind its normal operating schedule.
“The park appreciates the timely response by both law enforcement agencies and values the ongoing partnership and commitment to keeping our community and guests safe,” a Magic Mountain spokesperson said in a statement shared with ABC 7.
Officials did not disclose how the threat was communicated, and no suspicious devices or materials were discovered during the investigation.
The incident arrives during an already turbulent stretch for Six Flags. Earlier this year, the company revealed that Magic Mountain had lost more than $533 million in perceived value as part of a larger $1.5 billion accounting write-down tied to lower-than-expected earnings and attendance.
The adjustment followed the company’s 2024 merger with Cedar Fair, which left the combined business carrying more than $5 billion in debt.
Despite the financial strain, Magic Mountain remains one of the company’s flagship properties. In March, Six Flags announced plans to sell seven smaller parks to reduce debt, but the California location was not included in the deal.
The park has long been regarded as one of the chain’s most recognizable destinations, thanks to its record-setting roller coasters and its longtime presence in Southern California’s theme park market.
