For the more adventurous hiker, there are a number of other trails leading into the hills above Tennessee Valley.
With it's many trails, Tennessee Valley is well suited for the whole family. The area contains a bevy of wildlife; from mighty raptors to common swallows, the birds of the valley will keep your eyes on the skies. The skies are not the only place to view wildlife; the valley is teeming with deer, coyote, and on an occasion you might even see a bobcat.
