Cal-Sag Trail

The Cal-Sag Trail consists of over 13 miles of paved trails which meander near the Cal-Sag Channel from Lemont, Illinois in the west to Alsip, Illinois in the east in southwestern Cook County, Illinois through scenic wetlands and forests. Construction of an additional 13 miles to the east has been partially completed from Francisco Avenue and Wireton Road in Blue Island to the Metra Riverdale Station according to Friends of the Cal-Sag Trail; however, some portions such as on Vermont Avenue in Blue Island are designated bike lanes and not trails.



There are a number of parking areas along the trail. The Sag Quarries parking lot (near the intersection of Archer Avenue (Routes 83/171) and Old Archer Avenue in Lemont, Illinois) and Lake Katherine Nature Center (7402 Lake Katherine Drive, Palos Heights, Illinois) parking lot are highly recommended as starting points. A detailed map may be found here.
