The Hays Nature Preserve  (Site #30, Central Loop) hosts several miles of paved trails that follow the Flint River and its associated oxbow lakes through low riparian habitat, old fields, and a golf course.  There are a total of 10 miles of trails that wind through bottomlands, swamps, and sloughs, suitable for hiking or mountain biking. This is an incredible area, easily accessible for birders near the large metropolitan area of Huntsville.
