More than 30,000 people have come to the haunted house and scream park this season alone.
Each night at least 150 volunteers transform into zombies, ghouls and other creepy characters to scare the "yell" out of people.
They have several new attractions this year including Memory Manor and Ghostly Gallows.
After each season organizers will completely take a part every spooky room and start from scratch next year.
"This will be our grand finale. Our actors are pumped, it will be sad when we close, but we'll provide a good show for the rest of the week," says the suit-clad zombie character called "Death."
The Niles Scream Park is located off of US-12 on Mayflower Road. They will be open until 11 p.m. tomorrow and until 10 p.m. the rest of the week.
