I live in Texas, but I own two cabins in the Smokies, both of which are on trout streams.
Cabin On Roaring Fork is over 200 years old, and sits right on the Roaring Fork. I restored the cabin several years ago...you can see it here at www.CabinOnRoaringFork.com
. You can catch fish right off the porch. This is the oldest cabin in the Appalachian Mountains that is still inhabited, that I am aware of!
My other cabin, Cabin On River's Edge, is in Cosby, and is right on Cosby Creek. This is an extremely private, family cabin, sitting on 3 acres. It has over 300 feet of Cosby Creek frontage and is 5 minutes from the national park entrance. You can see it here at www.CabinOnRiversEdge.com
You can rent either one. In fact, I'm at Roaring Fork now...fishing was a bit slow today but we caught 3 - 2 brookies (one quite a large one!) and a bow.
