Denver Halloween Events Near Me

Searching for Halloween events near me in Denver? You picked the right city — and the right year, because Halloween 2026 lands on a Saturday. Denver goes hard every October (Visit Denver runs a full citywide calendar) — big costume parties, championship-grade haunted houses, zombie crawls, and one full-production blowout that has run for 19 years straight. Here is the short list of what actually fills up, and how to plan a night you will brag about.

Coloween 2026 — Denver’s Biggest Adult Halloween Party

Start here. Coloween is Denver’s biggest Halloween party and the one adult costume event locals plan their whole weekend around. The 19th annual runs Saturday, October 31, 2026 at the Bounce Empire in Denver — a 21+ full-venue takeover with a cash-prize costume contest that brings out serious competition. It sells out most years, so it belongs at the top of any Denver Halloween events list.

LoDo Zombie Crawl — The Casual Denver Halloween Crawl

One of the largest daytime Halloween events in Denver, the LoDo Zombie Crawl turns Lower Downtown into a sea of the undead. It is free to join, thousands show up in torn-and-bloodied best, and participating bars run drink specials all afternoon. If you want something loose and low-cost before the real party starts at night, this is the move. Check the crawl’s official page each year for the exact date and route.

13th Floor Haunted House — Denver’s Premier Scare

If you want to actually be scared, 13th Floor is Denver’s heavyweight. It ranks among the best haunted attractions in the country and rebuilds its houses with new themes every season. Expect a real line, real jump-scares, and a genuinely rattled walk back to the car. Great for a first-half-of-the-night warm-up before you head to a party.

Supernatural Festival — Halloween EDM at Scale

For electronic music fans, Supernatural is Denver’s largest Halloween-themed music festival, historically staged at the National Western Complex. Big-name DJs, Halloween production, immersive stages, and thousands of costumed dancers. It is a full-scale festival experience rather than a bar night, so plan for a later, higher-energy crowd.

More Denver Halloween Events to Check Out

• Denver Halloween bar crawls — hop between venues running drink specials. Budget-friendly and easy to build a group around.
• Broadway Halloween Parade — the family-friendly pick: floats, candy, and a festive non-party vibe for daytime.
• Neighborhood haunted attractions and pop-up haunts — smaller local scares that rotate every year across the metro.

When Should You Book Denver Halloween Events?

Now, honestly. Here is the pattern: Halloween searches start building in August and peak the week of October 25 — and that is exactly when the good ticketed events are already sold out or priced at their top tier. On a Saturday Halloween, that squeeze hits harder than any other year. Coloween tickets drop in August and the email list buys before the public, so the cheapest way in is to be on the list before you ever type "Halloween events near me" into Google.

Beyond that, match the event to the energy you want: a haunted house or bar crawl early, then a headline party to close it out. And build the costume around where you are going — the 2026 crowd will be full of Doctor Doom, Bride-and-Frankenstein duos, Vecna, and Wednesday looks. If you are hitting the Coloween costume contest, commit to two or three signature details you can hold all night instead of ten half-done ones.
