At HALLOWFEST, the Halloween thrills will be reimagined by adding safety precautions to reduce the spreading of germs. All guests will be required to make a reservation to avoid overcrowding (as we anticipate a lot of souls roaming the park during HALLOWFEST). Additionally, we’re going to continue adding a monstrous amount of protocols to keep you safe and healthy; so the only thing you’ll take home is loads of candy!

  • All team members (including scare-actors) and guests 3 years and up will be required to wear masks covering the nose and mouth while in the park.
  • No indoor mazes, haunted houses, or indoor shows will be operated; some haunted trails and scare zones will be operated outdoors with social distancing strictly enforced.
  • A limited number of nighttime scare-actors will always remain at least six feet away from guests and each other.
  • Guests viewing outdoor entertainment will be separated by at least six feet.  
  • All props, rides, restraints, handrails, dining, and restroom facilities will be cleaned and sanitized regularly. 
  • Multiple hand-washing and alcohol-based hand sanitizer stations will be located throughout the parks for guest and team member usage.
