Big Marsh Park

About Big Marsh Park

The vision of Big Marsh is to provide a new type of recreation in Chicago that marries habitat restoration with public use. Roughly 45 acres are developed for eco-recreation opportunities including hiking, adventure courses, and off-road biking. The eco-recreation elements are located primarily on existing slag fields where plants have a hard time growing and good habitat creation is unlikely. Other acreage is reserved for more passive recreation including bird-watching and nature walking. All acreage is being developed to protect or further enhance the overall natural habitat of the park property including sensitivity to flora, fauna, and wetlands. Through much planning, investment, and local stakeholder input, Big Marsh is now a safe, open, and inviting park space for Chicago and the neighboring communities.
