Denver is leaning into spooky season, and you don't have to wait until Halloween night to get in on the fun. From an immersive art experience on South Broadway to a haunted house in north Denver and a free costume party in Aurora, there are plenty of ways to make the most of the weekend.
If your plans need a little more Halloween energy, here are four local outings worth adding to your calendar for October 20–25.
1. Step Into an Immersive Halloween World at Spookadelia
Location: Spectra Art Space, 1836 S. Broadway, Denver
When: Open select days through December 2026
If a traditional haunted house isn't quite your thing, Spookadelia: Unspoken offers a different kind of adventure. This all-ages immersive experience at Spectra Art Space combines interactive installations, theatrical storytelling, technology, and art created by local artists.
Rather than simply walking through a gallery, visitors move through themed spaces and follow a story, solving clues and collecting tokens along the way. The experience is designed to be spooky without relying entirely on jump scares, making it an option for families, date nights, or anyone who enjoys unusual art experiences.
The current installment explores themes of truth, doubt, and self-discovery, with unexpected details throughout the journey.
Good to know: The experience includes indoor and outdoor areas, so dress for the weather. Advance tickets are recommended, and visitors should bring at least one charged smartphone per group.
Check availability and tickets at Spectra Art Space.
2. Get Your Adrenaline Fix at 13th Floor Haunted House
Location: 3400 E. 52nd Ave., Denver
When: Select nights through November 14, 2026
For those who want their Halloween plans to come with a few screams, 13th Floor Haunted House is back for its 2026 season.
This year's lineup includes multiple haunted attractions, including a Jason Voorhees experience inspired by the Friday the 13th franchise. Expect dark corridors, unsettling characters, elaborate sets, and the kind of atmosphere that makes you question why you volunteered to go first.
The experience also offers add-ons beyond the haunted walkthroughs, including axe throwing and other activities for visitors who want to extend their night.
It's a good pick for a group of friends looking for a classic Halloween outing, especially if you're the type who insists you're not scared right before grabbing someone's arm.
Good to know: The attraction operates on select nights, and tickets are sold online. Check the date-specific hours and ticket availability before heading over.

3. Have a Spooky Morning at Witches Tea
Location: Downtown Aquarium, Denver
When: Saturday, October 24, 2026
Halloween plans don't have to start after dark. The Downtown Aquarium is hosting Witches Tea on Saturday, October 24, with a themed high-tea experience that puts a playful spin on a traditional outing.
The event features Halloween-themed treats, smoking tea and punch, and special spooky animal appearances. Costumes are encouraged, so it's a fun excuse to dress up before Halloween weekend officially arrives.
Admission also includes access to the aquarium exhibits, making this a potential two-part outing: enjoy the themed tea, then spend time exploring the underwater displays.
This is one to consider for families or anyone who prefers their Halloween atmosphere more whimsical than terrifying.
Good to know: Confirm the event's start time, ticket requirements, and availability directly with the venue before booking.
