when is fright fest six flags 2023

Fright Fest at Six Flags in 2023 did not have one single nationwide date; each park ran its own Fright Fest schedule, but most U.S. parks held the event on select nights from early September through Halloween (around September 8–October 31, 2023).

Because dates varied by location (for example, Six Flags Magic Mountain’s Fright Fest in 2023 ran on select nights from September 8 to October 31), you’d need to check the specific Six Flags park’s 2023 calendar or archived event page for exact operating nights for that park.
