Grim Trails, Louisville

"Darkened woods are naturally scary, but fill them with sinister versions of your favorite fairy tales and they become especially unbearable," wrote Bailey Loosemore of the Courier-Journal after visiting Grim Trails. A 3/4-mile trek into the twisted realm of classic folklore and demented fables, this haunted attraction in the woods takes guests through a slew of bloodcurdling scenarios ranging from Wonderland's disorienting rabbit hole to Maleficent's dragon lair. The trail serpentines through indoor and outdoor areas populated with realistic sets, terrifying props, and real actors, prompting Phantom of the Ville to rank the attraction as the No. 1 Haunt in Louisville two years in a row. In fact, it's so intense at points that staffers recommend small children, individuals with heart issues, and women pregnant with child or demon sit this one out.
