Denver’s Ultimate Halloween Event Returns for 18th Season of Scares!

This year, Denver’s spine-chilling 13th Floor Haunted House returns to provide ghoulish thrills for its 18th season. As one of the nation’s most legendary haunted attractions, 13th Floor promises to deliver more screams, more scares, and more excitement than ever before.

“I couldn’t be more excited for 13th Floor Denver’s 18th season,” says General Manager Bryan Kopp. “We’re introducing some terrifying variations to our classic icon characters as well as adding brand-new characters to go along with our new attraction themes this year.”

Kopp continues, “We’ve added some jaw-dropping new scenes to our two indoor attractions that I can’t wait for guests to experience, but I’m even more excited for everyone to visit our two brand new, massive experiences we’ve added to the midway.”

Expanding from two main attractions to three, this year’s macabre experience begins with the Legend of the 13th Floor, where guests step into an elevator, only to find themselves suddenly transported to the lair of Mr. Hallows. Here, terrifying secrets roam free, and there’s no way back up.

Guests will then encounter Twilight of the Damned. Housed within the haunted Blackthorne Manor is a cursed and wretched asylum, and a vengeful witch has taken control of the patients, keeping them trapped in endless torment.

Finally, with The Blood Shed, a deranged butcher aptly known as The Carver has turned his ghastly tools on humans. Those who dare to enter will weave through eerie corridors in a desperate attempt to escape becoming The Carver’s next victim!

Beyond the main attractions, the 13th Floor midway offers a host of thrilling add-ons designed to keep adrenaline pumping all night long. Guests can play miniature escape games, sip on a personalized cocktail at The Sacred Skull, or test their nerves in No Name’s Clown Chaos, a maze filled with unsettling surprises and a spooky soundtrack.

13th Floor Haunted House is open now through select dates until Sunday, November 9, 2025. A complete seasonal calendar, including ticket prices and other details, are available here.
