The Great Western Trail in Illinois is a 30-mile multi-use trail that runs from Sycamore, IL at its western terminus to Villa Park, IL at its eastern terminus. It is divided into a Western Segment (17.55 miles) and an Eastern Segment (12.6 miles), which can be connected by surface roads (8.1 miles). The total mileage is 38.26. "The Great Western Trail crosses small streams and wetlands where duck, coot and the Great Blue Heron nest and raise their young. Shrubs, including Dogwood, Blackberry and Hazelnut mingle with the few remaining patches of native prairie. It is a place of quiet beauty, a linear wildlife refuge, and truly one of the finer experiences available in Kane County." (https://www.enjoyillinois.com/explore/listing/great-western-trail).
