The Morton Arboretum: Illumination: Tree Lights

About this adventure

Now in its 14th year, Illumination: Tree Lights at The Morton Arboretum in west-suburban Lisle turns 50 acres of majestic living trees into a breathtaking wonderland of light, color, and orchestral sound. Along a scenic one-mile paved walking loop around Meadow Lake and through the woods, visitors immerse themselves in interactive light features where hugging or singing to trees triggers luminous reactive color ripples across the canopy. The 2026 season introduces new installations alongside beloved classics like the Symphony Woods, Treemagination, and the enchanting Pine Whistle Railroad model train exhibition. Warming tents, outdoor fire pits with s'mores kits, warm hot chocolate, spiked hot beverages, and seasonal bites are stationed conveniently along the trail. The paved trail is completely accessible for strollers, wagons, and wheelchairs. Advance reservations with timed entry slots are mandatory, and guests are encouraged to dress in warm layers for the 60-to-90-minute evening woodland stroll.
