Six Flags México sits in the Tlalpan forest on the southern edge of Mexico City, making it the southernmost Six Flags park in North America. It first opened on March 3, 1982, as Reino Aventura, a park perhaps best remembered for once being home to Keiko, the orca who starred in the film Free Willy, before animal rights advocates pushed for his release back into the ocean.

Premier Parks acquired the property in 1999 for roughly $59 million, rebranding it as Six Flags México when it reopened on April 14, 2000. Today the park spans about 110 acres and is billed as the most-visited theme park in Latin America, drawing an estimated 2.8 million guests annually with a lineup of roughly 50 attractions, including 10 roller coasters.

The Ride Experience

The park’s marquee coaster is Medusa Steel Coaster, converted in 2014 from a wooden Custom Coasters International layout to Rocky Mountain Construction’s I-Box steel track. Designed by Alan Schilke, it reaches about 82 feet tall with a 118-foot drop, hits roughly 58 mph, and threads riders through three inversions across about 3,000 feet of track — notably, it was RMC’s first coaster built outside the United States and introduced the company’s signature barrel-roll drop.

Beyond Medusa, the coaster lineup includes Batman: The Ride, a Vekoma inverted looping coaster, The Dark Knight Coaster themed indoor attraction, and Batgirl Batarang, a Vekoma Boomerang model notable as one of the earliest Boomerang coasters ever built.

From Reino Aventura to Six Flags

Before its Six Flags rebrand, the park operated for nearly two decades as Reino Aventura, a name still recalled fondly by longtime Mexico City residents. Its transformation into Six Flags México in 2000 brought DC Comics theming, new steel coasters, and a broader push to align the park with Six Flags’ U.S. properties, while its forested Tlalpan setting remains a distinctive backdrop compared to other Six Flags parks.
