Illumination: Tree Lights at Morton Arboretum
Time Out says
When the weather gets cold, the trees at Morton Arboretum light up in a sea of color at this popular winter event. Guests at Illumination walk down a one-mile path through the forest, admiring the magical display and seasonal music. Enjoy the display while strolling along a one-mile path and then warm up by a crackling fire with hot beverages and s’mores.
