Denver Union Station turns its Great Hall into a Halloween party on Saturday, Oct. 31, from 7 to 11:30 p.m. The station describes a lively night of music, cocktails, dancing and costumes, with a DJ performing in the Great Hall, a costume contest and drink specials at two of the venues inside the building. Entry is free.
The event page lists no age policy, but the night is built around cocktails and dancing, so plan on it as an adult evening. Union Station sits on the A Line, the light rail lines into Union Station and the 16th Street MallRide, which makes it one of the easier Halloween-night destinations to reach without driving.
