Situated in an abandoned coffin factory built in the 19th century, Evil Intentions Haunted House encompasses 20,000 square feet of thrills and terrors inspired by the nearby cemetery and mental institution. The multi-storied madhouse sends shivers down spines with a cast of creepy characters, adrenaline-pumping surprises, and ghostly apparitions playing pinochle. Once built for the likes of presidents, the factory's remaining caskets now conceal frights that send guests skittering through the house's winding paths. Thrill seekers can leave their vehicles in the free parking lot and collect themselves in the house's indoor waiting area before beginning an adventure as twisted and chilling as the abominable snowman's DNA.
