Midewin National Tallgrass Prairie is the first national tallgrass prairie and, at 19,000 acres, the largest piece of contiguous open space in northeastern Illinois.
Midewin was established in 1996 on the former Joliet Arsenal. It is currently a "prairie under construction" as staff and volunteers restore the land from war plants to prairie plants. We offer many ways for you to enjoy your public land through hiking, biking, horseback riding, bird-watching, hunting and volunteering.
