Texas and Arkansas native
Lamar Hunt brought the Dallas Texans
AFL team, which he owned, to
Kansas City, Missouri, in 1963, renaming the franchise the
Kansas City Chiefs. He founded an operating company in the region called Mid-America Enterprises, which focused on real estate, mining, and entertainment. Worlds of Fun was conceptualized and developed by Hunt, his business partner
Jack Steadman, and theme park designer
Randall Duell. Construction began in November 1971 at the northern edge of
SubTropolis, a vast subterranean industrial complex developed by Hunt within a
limestone mine in the bluffs above the
Missouri River in
Clay County, Missouri. The project was completed over 17 months at an estimated cost of $20 million, and the park officially opened on May 26, 1973. Several years later, in 1989, Worlds of Fun ended the decade with the addition of
Timber Wolf, a
wooden roller coaster that initially ranked high in several national polls.
Cedar Fair LP purchased Worlds of Fun in 1995 for $40 million. The new owners invested $10 million with the addition of
Mamba, a
D.H. Morgan Manufacturing steel
hypercoaster, to the park's attraction lineup in 1998. During the
COVID-19 pandemic, the park operated under a limited schedule from 2020 to 2022. Worlds of Fun operated from June 22 to September 7 in 2020, while Oceans of Fun did not open that season. In 2021, the park opening was delayed until May 22, and until April 30 in 2022. On July 1, 2024, a
merger of equals between
Cedar Fair and
Six Flags was completed, creating Six Flags Entertainment Corporation. On March 5, 2026, Six Flags announced it would sell Worlds of Fun to
EPR Properties. The sale completed on April 6, 2026, making
Enchanted Parks its operator.
