A new list of America's most terrifying haunted houses in the US has been released, featuring names like "Field of Screams" and "Terror in the Corn."
The Haunted Attraction Association, the only official association of its kind in the US, has released its picks for the top 31 haunted houses in America ahead of Halloween, one for each day of October.
The attractions have all been certified after meeting a list of 10 criteria, with safety being one of the key requirements.
"The safety of our guests is the number one priority," said HAA President Brett Hays in a statement.
"The certification is a symbol of excellence that honors those attractions that are making strides above and beyond to focus on the safety and education of their employees, while developing a world-class haunting experience for guests."
