12 Midwest Backroad Scenic Drives
Parke County, Indiana
The drive: You'll find the nation's highest concentration of covered bridges (31, including the Billie Creek Bridge, left) in the Wabash River Valley (55 miles west of Indianapolis). Maps from the Rockville visitors center show color-coded routes to the historical spans, many of which still are open to traffic.
Worth a stop: Nearby Turkey Run State Park offers horseback riding and hiking (plus a family-friendly resort), and the Covered Bridge Art Gallery in Rockville shows work from 30 area artists. Another highlight: the annual Covered Bridge Festival in the fall.
