Taking a self-guided tour of this 1.3 mile trail through lowland woods and restored prairies by foot, bicycle or cross-country skis is a good way to learn about DuPage County's natural history. Most of the trail follows Salt Creek, providing visitors with the chance to see local flora and fauna. The half-mile walk along the banks of Salt Creek leads to Graue Mill Historic Site. Over a century ago, Frederick Graue put the waters of Salt Creek to work for him in a milling operation. Today, this National Historic Landmark allows visitors to see the mill operate as it did in Graue's day. The mill is open Tuesdays through Sundays from 10 a.m. to 4:30 p.m., mid-April to mid-November. For information about field trips, programs or admission fees, see www.grauemill.org or contact Graue Mill at (630) 655-2090.
