As of 2026, Six Flags Magic Mountain in Valencia, California, holds the world record for the most roller coasters in a single theme park, having surpassed the "20th coaster" milestone. The park solidified its lead in the "coaster wars" against its primary rival, Cedar Point, which currently sits at 18 coasters. The 20th coaster that officially broke the tie and set the record was Wonder Woman Flight of Courage, a Jersey Devil-style single-rail coaster that opened in 2022. Since then, the park has continued to expand, reinforcing its title as the "Thrill Capital of the World." This record is a point of immense pride for Six Flags and a major draw for coaster enthusiasts globally. While other parks like Energylandia in Poland are rapidly expanding and currently have 19 coasters, Magic Mountain’s historical dominance and diverse lineup of wooden, steel, flying, and 4D coasters keep it at the top of the Guinness World Records for the highest count in 2026.
