When is Six Flags closing two parks? What we know about closing dates

Summer 2025 will be the final season for one state's only Six Flags location.
Six Flags Entertainment announced the upcoming closure of Six Flags America and its accompanying waterpark, Hurricane Harbor, in a press release that called the move a "difficult decision." The Bowie, Maryland, location is the second planned closure announced by the company since May.
"As part of our comprehensive review of our park portfolio, we have determined that Six Flags America and Hurricane Harbor are not a strategic fit with the company’s long-term growth plan,” Six Flags President & CEO Richard A. Zimmerman said in a statement.
The announcement was shortly followed by news that Six Flags California's Great America of Santa Clara, California, would also be closing, though not until 2027. The amusement company currently operates 42 parks across the United States, Mexico and Canada, according to its website.
When is Six Flags America closing in Maryland?
Six Flags America and its accompanying waterpark, Hurricane Harbor Maryland, will both close their gates for good at the end of the 2025 season.
`According to Six Flags' press release announcing the closures, the location's final day will be Nov. 2, 2025. The parks' calendar details the specifics of the wind down, showing that both Hurricane Harbor and Six Flags America will begin operating on weekends only, plus Labor Day, beginning on Friday, Aug. 22.
Hurricane Harbor will welcome its last guests on Saturday, Sept. 6, but Six Flags America will remain open on weekends through the Halloween season for Fright Fest, officially closing its gates to the public on Sunday, Nov. 2.
When is Six Flags California's Great America closing?
Six Flags California's Great America won't close until the end of the 2027 season, unless the company chooses to extend or accelerate that timeline.
The park was originally poised to close by 2033, then-owner Cedar Fair told CBS News in 2022. That date was bumped up after Cedar Fair and Six Flags merged in 2024, in part due to the park's lease expiring, Paste BN previously reported.
“Unless we decide to extend, and exercise one of our options to extend that lease, that park’s last year without that extension would be after the ‘27 season,” Six Flags' chief financial officer, Brian Witherow, told investors in May.
