Although the latest round of health regulations forced the 140-plus-year-old mill to cease commercial operations, the waterwheel is still turning at this historic facility near Belvidere. In addition to a bed and breakfast and a museum of antique, water-powered machinery and even a dog-powered butter churn, Falls Mill is worth a visit just to sit in the placid picnic grounds along the creek to listen to the stream cascading across the wheel and into the pool below. Spring foliage is particularly dramatic in the woods surrounding the mill. For more information, go to fallsmill.com
