A holiday walk-through of decorated Christmas trees in the lobby of Greeley's Union Colony Civic Center, open on set days from Nov 21 to Dec 5, 2026. Kids can write letters to Santa, do a scavenger hunt among the trees and make crafts.
Know before you go. The Festival of Trees doesn't list sensory hours or a quiet room. Here's what the city says about the hours, the busy nights and the building rules.
