Illumination: Tree Lights at The Morton Arboretum features a one-mile paved path amid immersive lighting effects that highlight the beauty of trees in winter. Visitors can enjoy seasonal music, marvel at ever-changing, interactive lighting designs, and warm up by a crackling fire with a cozy drink or roast marshmallows for s’mores. Illumination will highlight the many gifts of trees: natural beauty, increased feelings of peace and calm, homes for wildlife, and the air we breathe. This year’s event will debut a new route with a more spacious pathway as well as new experiences such as Tree Fascination, which mixes art and science to showcase the color and pattern of trees with video projection.
