Even when they flows were at record lows....no problem!! I actually like the low water.
Dont worry about the crowds. I used to live in Gatlinburg and fished the park almost daily. Even when Gburg and Pigeon Forge are packed with visitors...i have never had a problem finding a quiet place on the stream.
Fall is my favorite time in the Smokies.....No worry about long cast's.
You have many options...all depends on where you are stayin. I have always stayed away from Little River....just cant find peace on the river that close to the road. To many bad-ass Lawyers and bankers riding there 40k bikes..scares me....
When you get close...send me a PM.....I will share some great spots.
