Howl-O-Scream is the annual haunt event that transforms the park into a horror filled adventure for guests. The separately ticketed event features walk-through haunted houses, roaming scare actors, special shows, and more. Each year the theme changes, and often features an icon or character that may have their own house or otherwise play a role in the event.
