This fall, one day at Six Flags Great Adventure can go from candy to coasters to creatures after dark. The Northeast's premier theme park destination is going big for fall in 2026, delivering a full day-to-night lineup packed with family-friendly Halloween experiences, seasonal food and entertainment, world-class thrill rides and one of the park's most ambitious Fright Fest lineups yet. Four new haunted mazes lead the charge this year, including JASON: Blood Reign and Final Destination: Death's Playground, inspired by two blockbuster horror franchises.
