Some of the finest treated groves in the Smokies are in the Cosby area. Gabes Mtn Trail is good with Bearneck Branch being among the finest stands. This district was hit last by HWA and success was high with treatments. Hoglen Branch in Cataloochee (NC) is really awesome- one of the few successes in the valley. Trees up to 15'5" girth in there. No trail but worth the short bushwhack.
