A dreadful collection of zombies, ghouls and demons will terrorize Halloween Horror Nights again when the annual fright fest returns to Universal Studios Hollywood.

Halloween Horror Nights 2025 will be back with a new lineup of haunted mazes and scare zones along with the Terror Tram on various nights from Sept. 4 through Nov. 2 at Universal Studios Hollywood.

Horror Nights 2024 ran on 40 dates, with marquee mazes dedicated to “Texas Chainsaw Massacre,” “Insidious,” “Ghostbusters,” “A Quiet Place” and pop star The Weeknd. Next year’s mazes are expected to be announced during the summer.

The separate admission Horror Nights event is not included with daily admission to Universal Studios Hollywood.

The Hollywood theme park has a full lineup of seasonal events planned for 2025.

The new Fan Fest Nights featuring “Harry Potter,” “Star Trek,” “Back to the Future” and Dungeons & Dragons promise to be a cross between Horror Nights and Comic-Con.

The separate-admission, after-hours events dedicated to sci-fi, fantasy, gaming and anime will run on various nights between April 25 and May 18.

The Wizarding World of Harry Potter will host Butterbeer Season from March 1 through May 31, and the Back to Hogwarts event from Aug. 1 through Sept. 1. Another seasonal event that has yet to be revealed will take over the park from June 14 through Aug. 10.

Bonus benefits: Feb. 1 through March 30

Collectible giveaways: May and November
