Published on December 19, 2025

The City of Centennial, in partnership with Trails Park and Recreation District and South Suburban Parks and Recreation District, is once again making it easy for residents to recycle their Christmas trees and holiday string lights after the season ends.

Beginning December 26, 2025, residents may drop off clean, undecorated Christmas trees and holiday string lights daily from sunrise to sunset at designated locations.
