Coloween Is a 21+ Halloween Party Inside an Inflatable Park
Coloween returns for its 19th year on Saturday 31 October 2026 at Bounce Empire in Lafayette, Colorado. Early entry starts at 9pm and general admission at 10pm, and the party runs until 3am across nine party rooms and a 360° stage, with house and techno DJs and an open bar. Entry is 21+ with valid ID. This year's theme: The Empire. Possessed.
Denver-area nights at the end of October are cold, with lows around 32–36°F (0–2°C). The party is indoors, so you only need a warm layer for travel and parking.
What to Wear to Coloween: Bold Looks for a $1,000 Contest
Costumes are required, and there's a $1,000 cash costume contest, so go bold and recognisable. Animal costumes like Mad Cat and Leopard, harlequin clowns, witches and zombies all read instantly across a crowded room.
For a possessed twist, try a creepy voodoo doll, a neon skeleton or a fantasy character like Elf Majesty or Dark Siren.
Group Costumes and Inflatable-Friendly Outfits
Coloween is in an inflatable park, so pick outfits you can move and bounce in: bodysuits and sets rather than bulky wings or hard props. The official rules say outfits must not block exits or create danger.
Coming with friends? Group costumes and matching couples looks stand out in a contest, and Toxic Skeleton and Sand Viper come in men's versions.
