Denver has one of the strongest haunt scenes in the Mountain West, and the metro spreads its attractions from Thornton and Henderson in the north down through Westminster, Littleton, and Englewood. This guide covers the best haunted houses in Denver for 2026, what each one is known for, and how to plan your visit across the Front Range. Opening weekends, hours, and prices shift from year to year, so always confirm the details on each attraction’s official site before you buy. Want the wider picture?

The best haunted houses in Denver

13th Floor Haunted House

One of Denver’s marquee haunts, 13th Floor Haunted House returns for its 18th season in 2026 with multiple attractions under one roof and typically runs on select nights from mid-September into mid-November. It is a big-production, high-scare experience with fast-pass options, and it consistently ranks among the busiest haunts in the metro, so booking a timed ticket online is the safe move on peak weekends.

City of the Dead

City of the Dead at the Mile High Flea Market in Henderson, just north of Denver, is one of the largest and most intense haunts in the area — more than 30,000 square feet split into three separate attractions on a single ticket. It leans heavily on scale and volume of scares, making it a strong pick for experienced haunt-goers who want a long night rather than a quick walkthrough.

The Frightmare Compound

In Westminster, on the metro’s northwest side, The Frightmare Compound is often billed as Colorado’s oldest haunted house and runs one of the longer seasons in the state, opening in mid-September for 2026. Beyond the main walkthrough it adds mini escape rooms, a monster museum, and a coffin simulator, so it works as a full evening out rather than a single attraction.

Haunted Field of Screams

Haunted Field of Screams in Thornton is the metro’s big outdoor scream park, combining a haunted field walkthrough, a zombie paintball ride, and a night maze on one ticket. It opens in late September for 2026 and runs through Halloween. Because it is largely outdoors, dress warmly — Front Range nights get cold fast in October.

Reinke Brothers and more metro haunts

Reinke Brothers Haunted Mansion in Littleton pairs a 30-plus-room walkthrough with a year-round Halloween and costume superstore, a Denver institution for decades. Beyond the marquee names, the metro’s directory also includes The Ritual Haunted House in Englewood, Horror Theater and Night of Terrors in Denver, World’s Scariest Haunted House in Littleton, and Bloxands Haunt in Aurora — smaller operations that round out the scene. And for a family-friendly-by-day, scary-by-night option, Elitch Gardens Fright Fest brings haunted houses and scare zones to the downtown theme park on select nights from late September through early November.

What to know before visiting a Denver haunt

Denver’s haunts range from family-friendly to genuinely intense, so scare levels vary widely — check each attraction’s stated intensity before you buy. If this is your first time, our first-timer’s complete haunted house guide walks through what to expect, and because so many metro haunts are partly or fully outdoors at altitude, our what to wear to a haunted house guide is worth a read before a cold Colorado night. Wondering how hard these places actually push? See how scary haunted houses really get.

Tips for visiting Denver haunted houses

• Buy online in advance. 13th Floor, City of the Dead, and the Frightmare Compound sell out prime October weekends; timed tickets and fast passes cut the longest waits.
• Plan for the drive. The metro’s haunts are spread from Henderson and Thornton in the north to Littleton and Englewood in the south, so pick a side of town or plan a multi-stop night.
• Dress for cold. Several attractions are outdoors, and Front Range evenings drop fast in October — layers and closed-toe shoes are essential.
• Confirm dates and prices on each official site before you go — hours and ticket tiers change season to season.
