Six Flags Great Escape & Hurricane Harbor's annual Fright Fest event will have you shaking in your boots! This month long celebration of all things spooky is the perfect event for kids and adults to celebrate Halloween. Fright Fest is the North Country's scariest Halloween celebration! The daytime at the park offers thrills and family-friendly activities that kids will love. Once the sun goes down, zombies and ghouls invade the park, and no place is safe from the scares. The fear factor is cranked up after 5:00 p.m.: fright-filled scare zones are located throughout the park, frightening shows last all evening, roaming hordes of terrifying creatures are set to scare around every turn, and thrill rides become more terrifying in the dark.
