Dungannon is the gateway to the world-reknowned Clinch River and the hiking and scenery of High Knob. The Scott County Horse Park, on the outskirts of Dungannon, draws visitors to frequent shows and festivals while the Flanary Archaeological Site, on the other side of town, has evidence of Native American occupation dating back 8,000 years. Cyclists and motorists revel in views of the Clinch River, waterfalls, and historical buildings spanning over 200 years along the Dungannon and Clinch River Scenic Road Tour.
The town also has a long history. Originally known as Osborne's Ford, the town was settled by Scotch-Irish and English immigrants who traveled here from North Carolina in search of land.
