Trail runners will consider it worth the journey to run the trails of the 2,800-acre Enterprise South Nature Park. The park, opened in 2010, is located 17 miles northeast of Chattanooga, and features about 10 miles of trails for those on foot (there are several miles of additional trails meant for horseback riding and mountain biking). The trails here are mainly wooded and tend to be moderately challenging, with some good hills. This trail map is an excellent resource, with suggested trail loops and difficulty ratings. The longer routes tend to be more difficult.
There are also some decent roads for running, with rolling hills. Some sections closed to cars — check with park staff as this can vary.
