Wilderness Landscape & Natural Heritage
Palos Forest Preserves spans over 15,000 acres in Cook County, Illinois, making it one of the largest natural areas within a short drive from a major metropolitan center. The preserves are characterized by rolling hills, mature oak and hickory forests, wetlands, and several lakes and streams including the Little Calumet River. Ecologically, the area supports diverse flora and fauna, including white-tailed deer, foxes, turkeys, and numerous species of migratory and resident birds. The preserves trace their origins to early 20th-century conservation efforts aimed at protecting green space and providing urban populations with accessible natural areas. Today, Palos Forest Preserves serves as a key outdoor recreation destination featuring an expansive network of multi-use trails for hiking, mountain biking, and horseback riding. Notable landmarks include the historic Red Gate Woods, which encompasses the site of secret Manhattan Project research during World War II. Visitors also enjoy fishing at Horseshoe Lake and exploring the peaceful paths near West Lake and Sag Bridge Woods. The preserves offer a family-friendly environment with picnic areas, fishing spots, and accessible trails. Its proximity to Chicago draws large visitor numbers year-round, providing a natural escape with large tracts of unspoiled forest, open prairies, and calm waterways. Wildlife viewing is excellent in all seasons, with spring wildflowers and fall colors attracting nature enthusiasts. The Palos Forest Preserves remain a vital green space for environmental education, outdoor recreation, and habitat conservation within the greater Chicago area.
