ILLINOIS' #1 SCARIEST HAUNTED HOUSE

Over 35,000 square feet of nightmares under one roof.

For more than 18 years, Massacre Haunted House has been terrifying the Chicagoland area from our home in Montgomery, Illinois. What began as a single haunted attraction has grown into one of the largest and most acclaimed indoor haunted house experiences in the Midwest — voted the #1 scariest haunted house in Illinois by Scare Factor and featured on WGN Morning News.

Located at 299 Montgomery Rd, right on the border of Aurora and Naperville and just 45 minutes west of downtown Chicago, Massacre draws tens of thousands of guests each Halloween season. Our location is easily accessible from across the western suburbs, and our massive free parking lot and on-site security make every visit straightforward from the moment you arrive.

What sets Massacre apart is scale and craftsmanship. We span over 35,000 square feet of indoor horror with 75+ nightmare-filled rooms, each renovated annually with custom Hollywood-grade set design, professional lighting, and practical effects. Every September our crew tears down, rebuilds, and reimagines large portions of the attraction so that even returning guests encounter rooms and scares they have never seen before.

Our cast includes over 100 live scare actors — trained performers who bring each scene to life with timing, intensity, and improvisation. Unlike walk-through displays with static props, Massacre is a living, breathing experience where actors react to your group, adjust their performance, and make every visit feel unique.

Start your journey in Massacre Haunted House, the flagship haunt featuring over 40 nightmare-filled rooms across movie-quality sets. Continue into the brand-new 2026 attraction The Asylum, a 3,000-square-foot expansion of clinical terror. Then ride the elevator down into subterranean industrial depths in The Underground, where the darkness closes in around you.

Beyond the haunts themselves, the Massacre midway offers escape rooms through our sister attraction Mind Trap, photo ops, a horror retail store, food trucks, and more — making the grounds a full destination rather than a single walkthrough.
