The oldest operating ride at Six Flags Great America is Columbia Carousel, which opened with the park in 1976. Standing over 100 feet tall, it remains one of the tallest and largest carousels in the world. For roller coaster enthusiasts in 2026, the Whizzer is the oldest operating coaster at the park, also having opened in 1976; it is one of the few remaining "Speedracers" in existence. While the legendary wooden racing coaster American Eagle (opened in 1981) is often cited for its age, it is actually five years younger than the park's original lineup. These classic attractions provide a nostalgic contrast to modern behemoths like Maxx Force, serving as a testament to the park's 50-year history of family entertainment.
