Shocktoberfest Scream Park summons spinal tingles across 30 acres of macabre attractions and chilling carnival games, which garnered praise as the No. 1 Must See Haunt by Haunted Attraction. All-access passes grant admission to each of the fright fest's four signature attractions, including the latest addition, The Unknown, which crowds steampunk corridors with ultramodern animatronics, 3-D cinematic effects, and the ghosts of Victorian-era machines. After mingling with monsters amid trendy tunes at Club Shock, fear seekers climb onboard an actual prison-inmate transport bus and travel to the Prison of the Dead, a cavernous 50,000-square-foot haunted penitentiary. Providing a welcomed respite from promenading through phantasmal fun, Biohazard Hayride lets passengers kick up their feet on a hair-raising voyage through a deserted industrial park with ominous flora, desolate power plants, and bloodthirsty zombies

Patrons in possession of RIP passes can forgo long lines held up by lurching ghouls and line-jumping specters, easing into each grim spectacle at their leisure. Those unable to spare any more bejesus can opt for strolls down the The Monster Midway, a tree-lined footpath adorned with crunchy autumn leaves, carnival games, and vendors peddling funnel cakes, burgers, and steak sandwiches.
