Events in the Nature Centers

Each center has self-guided nature trails, and naturalists to answer your questions. Programs throughout the year connect visitors with the intricate beauty of life in the natural world, and explore conservation issues. Learn about plants, animals and ecology of the Forest Preserves, go bird watching, follow tracks in the snow, make a model insect or listen to nature stories under the stars.


As the seasons turn, professional naturalists help visitors understand the science and meaning of nature’s wondrous changes. Most programs are free or available for a small charge.


Programs to open children’s eyes to nature include stories and crafts for families with pre-school age children, extended summer and winter break programs for elementary ages, and a Junior Naturalist program at River Trail NC. We are proud supporters of the Leave No Child Inside movement. Visit our Events page or ask for a program schedule today.
