See trees in a different light as we celebrate the power of coming together to lift our spirits during the crisp, long nights of winter! Illumination is an award-winning, one-mile outdoor walking tour on a paved path winding through 50 acres of The Morton Arboretum’s celebrated tree collections. Seating, warming/concession tents, and fire pits are available along the route. So are countless photo opportunities. It’s an ideal way to experience the winter woods brought to life with innovative lights, projections, and music.

This year, we’re introducing the Illu-medallion. Groundbreaking technology lets you be part of the interactive light display when you purchase a glowing, wearable Illu-medallion that reacts to the spectacular sights and sounds along your journey.

Most of the Illumination path is accessible to people who use wheelchairs and other mobility aids; see the accessibility section for details. The exhibition is not accessible by car and cannot be experienced from the road.
In its fifth year, Illumination has become a tradition and a can’t-miss holiday event.
