The Des Plaines River Trail is a recreational multiuse trail that follows the course of the Des Plaines River through most of Lake and part of Cook County in northeast Illinois in the United States. Trail uses include hiking/walking, bicycling, equestrian, and even winter cross country skiing and snowmobiling (conditions permitting). Since much of the trail lies in the flood plain along the Des Plaines River, sections of the trail are occasionally closed due to flooding during periods of heavy rain. Though not all sections of the trail connect directly, there is a section more than 31 miles (50km) long running through Lake County starting at Russell Road along the Wisconsin/Illinois state line and running south into Cook County. There are additional disconnected sections south of the town
