Mac, the Gorge is the area starting above the Chimney Tops Picnic Area then up to the confluence of Walker Camp Prong and Road Prong (The Chimney Tops Trail).
The "nature area" I was referring to is just before the tunnel on US441 toward Newfound Gap (on the right hand side). There is a pulloff/parking area and a few pathways down to the river from there.
The farther up you go, the more brookies you will find...
