Chicago’s cherished outdoor holiday light show, Illumination: Tree Lights at The Morton Arboretum, returns for its 13th year starting Saturday, Nov. 15, running through Jan. 3, 2026, according to a press release. This interactive event attracts visitors of all ages to stroll a one-mile, ADA-accessible trail where dazzling lights highlight the Arboretum’s winter landscapes.
Last year, Illumination was nationally recognized by USA TODAY as one of the top 10 “Best Botanical Garden Holiday Lights.”
