Halloween 2026 lands on a Saturday — the first since 2020 and the last until 2037 — and the Denver metro is treating it accordingly. The season opens September 11 and runs nearly two months, ending with everything converging on one enormous Saturday night. Here’s the whole calendar: the haunts, the parades, the family nights, the bar crawls, and the big October 31 — with the night itself broken out by geography, because on a Saturday Halloween, where an event is decides how your night ends.

Halloween night in Denver & the metro — Saturday, October 31

The night everything runs at once, with clocks falling back at 2 AM to make it a 25-hour night. The hour-by-hour breakdown lives in our Halloween Night Guide; here’s the metro roster:

Time Event Where Ages
Morning Trick or Trot 5K/10K — costumed run Piney Creek Hollow Park, Centennial All ages
Daytime Boos & Brews Halloween 5K — beer at the finish line Number Thirty Eight, RiNo 21+ to drink
Daytime Samhain Market — witchy wares, readers, dark art, and mystical finds 1111 Broadway, Denver All ages
Afternoon Nightmare Before Christmas with the Symphony (matinee) Boettcher Concert Hall All ages
4 PM–10 PM Official Halloween Bar Crawl — wristband access to participating downtown bars; a separate Zombie Crawl bar crawl runs Oct 31–Nov 1 Downtown Denver 21+

9 PM–2 AM DarknessCon: Dark Harvest Masquerade Ball — the ~$10 ticket of the night Castle Event Center, Thornton 18+

Halloween night in Boulder County

A chunk of the night lives 45+ minutes northwest of the city — worth knowing before you commit, because on a Saturday Halloween the drive back is part of the ticket price.

Time Event Where Ages
Morning Longmont Halloween Parade & Trick-or-Treat Street — free, no registration Roosevelt Park & Main St, Longmont All ages
Daytime Munchkin Masquerade — Pearl Street’s trick-or-treat tradition for ages 12 and under Pearl Street Mall, Boulder Kids
Day/eve Anderson Farms Fall Festival — final day of the season Erie All ages
9 PM–3 AM Coloween — open-bar party inside an indoor inflatable park, capped crowd, opening tier listed at $79 Bounce Empire, Lafayette 21+
Evening Terror in the Corn — haunted corn maze and scare trail; closing night runs latest into the dark Erie All ages, intense

The logistics reality for anything on this list after dark: budget 45 minutes to an hour back to the Denver metro, at exactly the hours surge pricing peaks on the biggest going-out night of the year.

For families

The family season’s anchors: Glow at the Gardens (Oct 15–18 and 21–24 — buy early, it sells out weeks ahead), Magic of the Jack O’Lanterns at Hudson Gardens all season, the free Broadway Halloween Parade on Oct 17, Día de los Muertos at Civic Center Park on Oct 24, Spirits + Songs at the opera house Oct 28, and the Symphony’s Nightmare Before Christmas Oct 29–31. On Halloween itself: Boulder’s Munchkin Masquerade, Longmont’s parade, and neighborhood trick-or-treating from sunset (about 5:59 PM) to 8-ish. Olde Town Arvada’s Trick or Treat Street runs Friday the 30th. Boo at the Zoo hadn’t posted 2026 dates at our last update — see the pending list below.

Not yet announced for 2026

These Denver traditions are expected but hadn’t published 2026 dates when we last checked, so we won’t guess at them: 13th Floor Haunted House (attractions for the season are announced — Legend of the 13th Floor, Twilight of the Damned, The Blood Shed — but dates are TBA; it typically runs early September through early November), Boo at the Zoo at the Denver Zoo, Reinke Brothers Haunted Mansion in Littleton, City of the Dead, and the Chatfield Farms corn maze. We’ll move each one into the calendar above the day its dates go live.

Guests in costume at the Paranormal Palace Denver Halloween party

If you’re here for Halloween night itself

You just read the whole season — but if what you actually want is the night, Saturday, October 31 is ours. Paranormal Palace takes over the entire DoubleTree DTC: an 8,000 sq ft Haunted Forest ballroom, a multi-level atrium over the dance floor, three DJs, 20+ performers, and Colorado’s largest costume contest at $2,500. And unlike every other event on this page, it ends with an elevator ride, not a surge-priced curb. The 41 balcony rooms sold out in August — discounted standard rooms remain, and they still buy you the elevator. Compare it honestly against everything above in our five-test party scorecard, study the contest, or just:

The Palace closes at 1. Your room doesn’t.

How this page works: every date above was checked against the organizer’s own website or the official Visit Denver events calendar. Events without confirmed 2026 dates sit in the pending list instead of the calendar — we’d rather be incomplete than wrong. We re-verify as the season approaches. Spot an error or run an event we missed? Tell us and we’ll fix it within the week. More planning tools: the Halloween Night Guide and the 21+ adults-only guide.

Quick answers

The season anchors are Elitch Gardens Fright Fest (Sept. 26–Nov. 1), the Frightmare Compound in Westminster (Sept. 11–Nov. 7), Glow at the Gardens at Denver Botanic Gardens (Oct. 15–18 and 21–24), the Broadway Halloween Parade (Oct. 17), and Halloween night itself — Saturday, October 31 — when Paranormal Palace at the DoubleTree DTC, DarknessCon’s masquerade ball in Thornton, the downtown bar crawls, and Boulder County’s Coloween all run on the same night.
The Frightmare Compound opens September 11 and runs through November 7. Elitch Gardens Fright Fest runs September 26 through November 1. Magic of the Jack O’Lanterns at Hudson Gardens runs September 18 through November 1. 13th Floor hadn’t published its 2026 dates at our last update; it typically runs early September through early November.
It’s a Saturday, so everything converges: Paranormal Palace (21+, DoubleTree DTC, 8 PM–1 AM), DarknessCon’s Dark Harvest Masquerade Ball (18+, Thornton), downtown bar crawls, the Samhain Market on Broadway, a Boos & Brews 5K, the Symphony’s Nightmare Before Christmas matinee, the free Longmont Halloween Parade and Boulder’s Munchkin Masquerade for kids, Boulder County’s Coloween in Lafayette, and the final nights of most haunted attractions and pumpkin patches.
Glow at the Gardens (Oct. 15–18 and 21–24) for illuminated pumpkin displays, Magic of the Jack O’Lanterns at Hudson Gardens (Sept. 18–Nov. 1), the Broadway Halloween Parade (Oct. 17), Día de los Muertos at Civic Center Park (Oct. 24), the Symphony’s Nightmare Before Christmas (Oct. 29–31), Boulder’s Munchkin Masquerade on Pearl Street (Oct. 31), and Boo at the Zoo, whose 2026 dates were still pending at our last update.
Glow at the Gardens sells out weeks in advance every year according to its organizers. And because Halloween 2026 falls on a Saturday — the first since 2020 — the big October 31 parties concentrate demand: Paranormal Palace’s 41 atrium balcony rooms overlooking the dance floor sold out in August, standard rooms at the DoubleTree remain for now, and earlier ticket tiers cost less than later ones.
