Colorado Halloween Party Photos
Nineteen years of the best Colorado Halloween party — costumes, crowds, and the transformation — in photos.
By JJ Walker · Updated July 2026
Photos tell you more about Coloween than any description can. Nineteen years of costumes, packed dance floors, and a venue transformed for one night — this is what Denver’s biggest Halloween party actually looks like. Browse the full gallery below, then get on the list before tickets drop.
See the full photo gallery here: the Coloween mosaic gallery — thousands of real shots from 2019 to 2025, every one a guest who showed up in costume.
The Halloween Costumes That Fill the Gallery
Coloween is a costume event first. Every year the gallery fills with group builds, couples who commit all the way, and one-off looks that win the Coloween costume contest. If you want proof that people go all out, the photos are it — this is a room where showing up in a last-minute mask means you’re underdressed. The 2026 pages will fill fast with Doctor Doom, Wednesday looks, and Bride-of-Frankenstein couples if trend lines hold.

What Does Colorado’s Biggest Halloween Party Look Like?
The biggest 21+ Halloween party in the state, all in one transformed space. The photos capture what a headcount can’t — the energy of a full floor and a crowd that came to go all night.
The Venue Transformation
Coloween 2026 takes over Bounce Empire in Lafayette and turns it into an adult Halloween world for the night. The before-and-after is half the fun, and the gallery shows how far the transformation goes. If the photos make you want the real thing, see what the Coloween experience feels like inside.
See It, Then Be In It
The best photo from next year’s gallery could be you. Coloween 2026 is Saturday, October 31 — the 19th annual, on Halloween night itself.
