Short trips in East Tennessee?

I see no one has mentioned one neat option right in your back yard ... Frozen Head State Park. The park is quite mountainous for the area and has miles of hiking trails. It also has a small campground that is suitable only for tents or smaller RVs partly because it is accessed via a one-lane bridge that ties in to the main road at a right angle. Be prepared to boondock as there are no hook-ups but it does have water faucets and a restroom. Best of all there is a trail out of the CG that is an old fire tower access road so nice and wide. Being close to your home it would make a good location to minimize travel time and maximize relax time. Welcome to TN!

* Oops! Looking back I see Kohldad mentioned Frozen Head.
