About this event

The 13th Floor Haunted House Denver returns for the 2026 Halloween season from September 11 through November 14 with its biggest nightmares yet, headlined by the all-new, officially licensed Jason Universe: Survive the Night. For the first time, guests can step into the terrifying world of Jason Voorhees in an immersive Friday the 13th experience where the legendary masked slasher is on the hunt. The 2026 season also introduces two chilling new attractions, The Stitchworks: House of Reanimation and Cathedral of the Crimson Queen, plus Jason Universe: Director’s Cut, an interactive experience that puts guests in control of Jason’s next move. Beyond the haunts, the expanded midway features mini escape games, axe throwing, secret bars, Tiki Tarot, RIP cabanas, food and drinks, and more. Tickets start at $19.99 on select nights for one of the nation’s premier haunted attractions.
