Six Flags AstroWorld

Six Flags AstroWorld was an amusement park in Houston, Texas, situated roughly 8 miles south of downtown. The park featured several roller coasters including the wooden Texas Cyclone and water-based attractions such as Thunder River.

The park opened on June 1, 1968, launched by Judge Roy Hofheinz as part of his Astrodomain development alongside the Astrodome stadium. Financial troubles and falling visitor numbers led Six Flags to close it in 2005 and sell the land.

The name comes from Houston's ties to space exploration and the nearby Astrodome sports complex. Visitors recall rides decorated with space themes that gave the feeling of embarking on a futuristic journey.

During its operating years, the park sat between Kirby Drive and Fannin Street south of Interstate 610 and was convenient to reach by car. Today, only an old pedestrian bridge spanning the highway remains as a trace of the former facility.

A Disney Studios animator created a detailed scale model of the park that even included a tiny black Cadillac. The Greezed Lightnin' roller coaster stood out among guests for its thrilling inversions and left lasting memories.
