Haunted Houses in Denver 2026

Denver takes Halloween seriously, and the haunted houses in Denver are the proof. Every October the metro fills up with actors in the dark, chainsaws that are hopefully props, and mazes built to make grown adults scream. If you want your adrenaline wrecked before the party starts, here’s the local rundown — the seven scariest attractions worth the drive, and where to land afterward when you’d rather be dancing than running. For the landing spot, see adults-only Halloween events in Denver.

The 7 Best Haunted Houses in Denver

These are the names that come up every year when Coloradans argue about the best haunted houses Denver has to offer. Details like exact dates and ticket prices shift season to season, so check each attraction’s own site before you go — but this is the shortlist worth building a night around. Two locks already: 13th Floor Haunted House and The Frightmare Compound are both back for the 2026 season.

• 13th Floor Haunted House
• Haunted Field of Screams (Thornton)
• Fright Fest at Elitch Gardens / Six Flags
• The Frightmare Compound (Westminster)
• The Asylum (Henderson)
• City of the Dead (Henderson)
• Reinke Brothers Haunted Mansion (Littleton)

13th Floor Haunted House

The one most people name first. 13th Floor built its reputation as one of the scariest haunts in the state, leaning hard into the superstition that buildings skip the thirteenth floor for a reason. Elaborate sets, relentless actors, and a line that says everything about how well it works. If you only hit one, hit this one.

Haunted Field of Screams

Out in Thornton, this is a full outdoor complex rather than a single walkthrough. Multiple attractions in one stop — a haunted maze, a zombie paintball ride, and more corn than anyone should trust after dark. Good pick if you want a couple of hours of scares instead of one quick jolt.

Fright Fest at Elitch Gardens

There’s something uniquely wrong about a theme park after sundown. Six Flags flips Elitch Gardens into Fright Fest every fall — the rides stay open, fog rolls in, and scare actors work the midways. Two attractions in one: coasters by day, chills after dark.

The Frightmare Compound

A Denver institution. The Frightmare Compound in Westminster has been terrifying people since the ’80s, and the old-school pedigree shows in how committed the whole thing is. An entire compound built for the sole purpose of scaring you — exactly the kind of place to warm up before Denver’s biggest Halloween party.

The Asylum

Located off 88th Ave. in Henderson, The Asylum has landed on national "scariest in America" lists more than once. The theme is exactly what it sounds like, and it commits all the way. Not the pick for anyone squeamish about tight hallways and things lunging out of them.

City of the Dead

Right next door to The Asylum, City of the Dead goes all in on the undead. If zombies are your particular nightmare, this is the walkthrough that finds it. Pair it with The Asylum for a brutal one-two Henderson double feature in a single night.

Reinke Brothers Haunted Mansion

A little off the beaten path in Littleton, Reinke Brothers is two things at once — a beloved year-round costume shop and a genuinely creepy haunted mansion. Swing by early in the season and you can knock out a scare and your Halloween costume in the same trip.

Are Haunted Houses in Denver Worth It?

Haunted houses are a rush, but they’re a walkthrough — twenty minutes of screaming and then you’re back in a parking lot. When you’re done being chased and want a night that actually goes somewhere, that’s where Coloween comes in.

Where the Adults Go After: Coloween

Coloween is Colorado’s biggest 21+ Halloween party, and 2026 is the 19th year running it. Saturday, October 31, 2026 — Halloween night itself — at Bounce Empire in Lafayette, a night built for people who’d rather be in the crowd than in a corn maze. Wear the costume you actually spent money on and put it to work in the Coloween costume contest. Do the haunted houses for the scare. Come to Coloween for the night.
