During the Halloween season, Six Flags Great Adventure is redecorated with spider webs, smoke machines, and other Halloween related decorations. Actors dress up in scary costumes and walk around to frighten guests, as they once did at the Haunted Castle. Fright Fest typically begins at 6:00 PM, as the zombies parade to a stage to kick off "fright by night." The park does not recommend the nighttime activities for children 13 or under. Fright Fest attracts some of the heaviest crowds of the year, and becomes more and more crowded as the date draws closer to Halloween.
