Coloween 2026: 19th Annual Halloween Party (21+)

Coloween is 21+ and this is year nineteen, Colorado's longest running adult Halloween party.

It takes over all of Bounce Empire in Lafayette, the world's largest indoor inflatable park. 50,000 square feet, 50 attractions, zero kids. That night the building belongs to 1,200 adults in costume.

Everything runs. The slides, the obstacle courses, the quarterback challenge, the 42-foot bounce dome. Grown adults go down a slide at 1AM in full costume. That is the party.

Colorado's top house music DJs play the 360 degree concert stage under a full concert lighting rig. Nine party rooms. Lasers, projection walls, disco balls, fog.

Open bar all night, premium alcohol, included in the ticket. $1,000 cash for the best costume.

Halloween lands on a Saturday in 2026 and will not again until 2037. The clocks go back that night, so 2AM happens twice. You get the extra hour.

Saturday, October 31, 2026. 9PM to 3AM. 21+, costume required. From $79 all in, no added fees and no service charge at checkout.
