The Red River Gorge is a uniquely scenic area in the Daniel Boone National Forest. The area is known for its abundant natural stone arches, unusual rock formations, and spectacular sandstone cliffs. The Red River Gorge is designated as a national geological area by the U.S. Forest Service.

Starting in 1912, 25-ton and 35-ton Climax locomotives hauled logs for about fifteen miles through the tunnel to the Clay City sawmill. The tunnel brought loggers into the gorge and served as a means to transport wood products. Today the tunnel brings tourists into the gorge to enjoy and experience its natural wonders. The rugged appearance of the tunnel serves as a reminder of the work and labors of early settlers in the area.
