Six Flags announced plans to shut down one of its California theme parks during a recent investors' meeting months after a previous closure in Maryland.

The popular theme park chain will close its California's Great America location in Santa Clara at the end of the 2027 season, prior to the conclusion of its lease in three years.

“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,” Witherow said via PEOPLE while answering questions at Six Flags Investor Day 2025 on May 20.

Six Flags America had previously announced the closing of its Bowie, Maryland, location set to take place at the end of the 2025 season.

“Those are two parks that are very low on the ranking of margins,” Witherow said.

The 100-acre Santa Clara park, which opened under the Marriott Corporation as Marriott's Great America in 1976, would be set to close after the 2027 Halloween season. Cedar Fair merged with Six Flags as part of an $8 billion deal in 2024, having previously sold 112 acres of land underneath the park to Prologis as part of a $310 million deal.

The company agreed to lease back the land and had previously announced plans to shut down the park at the completion of the lease, which was set to end in 2028 with an option to extend through 2033.

“We chose Prologis as our partner because of their deep ties in the Bay Area and their reputation for working closely with local communities on large developments,” said then-Cedar Fair president and CEO Richard A. Zimmerman in a press release shared in June 2022 via PEOPLE.
