Nada Tunnel (measuring 12’ high, 12’ wide, and 900’ long) is the gateway to the Red River Gorge Geological Area. It was constructed to access the abundant natural resources of the Gorge. Dynamite, steam drills, and hand tools were used to dig the tunnel from December 1910 to September 1911. During the early 1900’s, logging was a major industry in the Red River Gorge. Logs were transported by railroad through this tunnel to the sawmill at Nada. The name comes from rearranging the letters of “Dana” from the Dana Lumber Company. Today, the tunnel is on the National Register of Historic Places and is used by modern visitors to access forest scenery, geologic features, and recreational opportunities.
