Announced in November 2023 as a merger of equals, former Cedar Fair leadership remained in control of the new company, along with two former Six Flags executives.

[3] A proposal in 1974 to build an amusement park in Cambridge Township, Michigan, was contemplated and later abandoned the following year.

The acquisition included operations of the Camp Snoopy indoor park at the Mall of America in Bloomington, Minnesota.

In 2005, Cedar Fair withdrew from the lease arrangement leaving Mall of America to manage the park on its own.

Cedar Fair purchased the park for $145 million, reverting its name to Geauga Lake, as it was before its Six Flags branding in 2000.

[14][15] Subsequently, Cedar Fair stripped the park of all references to Looney Tunes and DC Comics characters which were licensed properties owned by Six Flags.

The zoological and marine life portion of the complex (SeaWorld Ohio), which was annexed to the theme park in 2001, was also shuttered.

On June 30, 2006, Cedar Fair announced that it had completed its acquisition of Paramount Parks from CBS Corporation in a cash transaction valued at US$1.24 billion.

[27] On April 6, 2010, the deal was terminated, and Cedar Fair paid $6.5 million to reimburse Apollo for expenses incurred from the proposed transaction.

[29] On September 16, 2011, JMA Ventures, LLC entered into an agreement to purchase California's Great America from Cedar Fair and take ownership of the Gilroy Gardens management contract.

[30][31] The agreement required approval of Santa Clara's city council which was scheduled to vote on the matter on December 6, 2011.

On November 20, 2012, Cedar Fair announced it had sold its Knott's Soak City: San Diego location to SeaWorld Parks & Entertainment.

[36] About nine months later, Cedar Fair announced it had sold its Knott's Soak City: Palm Springs location to CNL Lifestyle Properties.

On October 4, 2017, Cedar Fair announced that Ouimet would step down as CEO and be succeeded by COO Richard Zimmerman on January 1, 2018.

Ouimet would remain with the company, taking the newly created position of executive chairman of the board of directors.

[39] On March 27, 2019, Cedar Fair announced it was purchasing the land occupied by California's Great America from the City of Santa Clara.

Cedar Fair had been previously leasing the land from the County of Santa Clara for 6 to 7 million per year.

Both Gilroy Gardens Inc., the nonprofit that owns the park, and Cedar Fair agreed not to renew the contract.

[51] On February 1, 2022, news broke that United Parks & Resorts made an unsolicited all-cash bid to buy Cedar Fair for $3.4 billion.

For an increased cost, visitors get a wrist band which gives them the ability to wait in a shorter queue for most attractions.
