Southern California’s ultimate haunted house returns this fall. Reign of Terror Haunted House, located at Janss Marketplace in Thousand Oaks, officially opens its 2026 Halloween season on September 25th, bringing guests an expanded 35,000-square-foot attraction featuring 145 rooms across 12 (2 of them brand new) terrifying themes.
For 2026, Reign of Terror is introducing two completely new sections: “The Blue Bayou Hotel” and “Backwoods”. Both areas have been built from the ground up with new environments, props, characters and scares while delivering the elaborate sets, immersive atmosphere and relentless scares Reign of Terror has become known for.
In The Hotel, guests enter a sinister new environment where checking in may be considerably easier than checking out. Backwoods takes visitors into a secluded and decaying world far removed from civilization, where they’ll quickly discover they aren’t alone. Together, the two additions represent a major expansion of the Reign of Terror experience for the 2026 season.
And the changes don’t stop there.
The fan-favorite Fun House has been extensively remodeled for 2026, introducing new scares and surprises throughout the section. Reign of Terror has also significantly expanded its post-haunt photo experience, adding large-scale themed sets and props where guests can capture photos after surviving the attraction.
The expansion brings Reign of Terror to an enormous 35,000 square feet, 145 rooms and 12 interconnected themes, continuing the attraction’s reputation for delivering an unusually long haunted-house experience packed with detailed environments, live performers, special effects and scares around seemingly every corner.
Now entering its 27th year, Reign of Terror has grown from a local Halloween attraction into one of Southern California’s most elaborate haunted-house experiences. Its combination of Hollywood-quality sets, professional scare actors, immersive environments, extensive walkthrough and comparatively affordable admission continues to attract tens of thousands of horror fans each Halloween season.
“This was the BEST haunted house/maze I’ve ever been to! 10x better than horror nights at less than one third the price. The production value is like ‘muah’ chef’s kiss. Horror/Halloween fanatic approved,” – said one Yelp reviewer from the San Fernando Valley.
