Wilderness Landscape & Natural Heritage
The Cook County Forest Preserves - Palos Complex spans over 15,000 acres in southwestern Cook County, Illinois, making it the largest concentration of forest preserves in the county. The area protects a variety of natural environments including hardwood forests, wetlands, prairies, and creek corridors. This diverse habitat supports numerous species of birds, mammals, reptiles, and native plants. Historically, the preserves were once agricultural and gravel mining lands that have since been restored to a more natural state. Visitors can enjoy over 75 miles of multi-use trails that accommodate hiking, mountain biking, horseback riding, and cross-country skiing in winter. The preserves feature several small lakes and creeks such as the Little Calumet River, offering fishing and paddle sports opportunities. Notable landmarks include the historic Bluff Spring Fen, an ecological preserve home to rare plant species, and I&M Canal Trail access points. The Palos Complex is popular among outdoor enthusiasts of all ages, families, and bird watchers. Its proximity to Chicago makes it a valuable green space for city dwellers seeking a nature escape. The preserves are managed by the Forest Preserve District of Cook County, which maintains the land for both recreation and conservation purposes, including habitat restoration and invasive species control. With numerous picnic areas, interpretive centers, and equestrian facilities, the Palos Complex offers a wide variety of outdoor experiences year-round.
