Nada Tunnel
Nada Tunnel Rd (KY 77)
Clay City, KY
A 900-foot tunnel blasted through solid rock for a logging railroad, now a one-car-at-a-time doorway into the Red River Gorge.
Nada Tunnel is one of the most memorable pieces of road in Kentucky, and it is barely a road at all. Cut straight through a sandstone ridge, it runs about 900 feet long but only wide enough for a single vehicle, so drivers pull up to the mouth, peer through to be sure no one is coming the other way, and then ease into the dark. On the far side, the Red River Gorge opens up, which is why the tunnel has long been nicknamed the Gateway to the Red River Gorge.
The tunnel was never meant for cars. It was blasted through the ridge in 1910 and 1911 for the Dana Lumber Company, so a locomotive could haul logs out of the Gorge to the company's sawmill down in Clay City. Workers drove it through the limestone and sandstone with steam drills, machinery, and dynamite, and the rough, unlined walls still show the marks of that hard, dangerous work. When the trains stopped, the tunnel found a second life as the doorway thousands of hikers, climbers, and campers pass through each year.
What Guests Love
- Driving through a genuine hand-cut tunnel just one lane wide, taking turns with oncoming cars
- The sense of crossing a real threshold into the Red River Gorge on the far side
- The raw, unlined rock and the drip of water inside, a tunnel that looks its full age
- The logging-era story of how and why it was blasted through the ridge
Worth Knowing
- The tunnel is only wide enough for one vehicle, so you must stop, look through, and wait your turn, and it is not the place for large RVs or trailers
- It is unlit inside, so headlights on, roll slowly, and expect a low, close ceiling
- It can be busy and slow on fall weekends when Gorge traffic peaks, so patience helps
- There are no services at the tunnel itself, so plan for gas and food in Stanton or Slade

Learn about Nada Tunnel
A tunnel for hauling logs
In the early 1900s logging was king in the hills of eastern Kentucky, and the timber-rich Red River Gorge was a prize. The trouble was getting the felled trees out over such broken terrain. The Dana Lumber Company's answer was to punch a rail tunnel straight through a ridge so a small locomotive could carry logs from the Gorge to its mill in Clay City rather than fight the long way around.
The work was brutal. Between December 1910 and September 1911, crews bored through the rock with steam-powered drills and blasted their way forward with dynamite, and the tunnel that resulted measured roughly 12 feet wide and 13 feet high, just enough for the log train. The tunnel took its name from Nada, Kentucky, a small logging town that once stood miles beyond it and has since all but vanished.
From railroad to gateway
When the timber ran out and the logging railroad was abandoned, the tunnel could have been forgotten. Instead its narrow bore was pressed into service as a one-lane road, and because it lay squarely on the western approach to the Gorge, it became the classic way in. Today Kentucky Route 77 threads through it, and passing through the dark, dripping tunnel has become a small rite of passage for anyone heading to the cliffs and arches beyond.
The tunnel remains almost exactly as the loggers left it: unlined rock overhead, water seeping down the walls, and barely room for a single vehicle. That authenticity is the whole appeal. It is not a modern, tiled highway tunnel but a raw survivor of the logging era, and driving through it feels like slipping backward in time on the way to one of Kentucky's great natural wonders.
The Red River Gorge beyond
What waits on the other side is the reason people come. The Red River Gorge Geological Area, part of the Daniel Boone National Forest, is a maze of towering sandstone cliffs, deep green hollows, and more than a hundred natural stone arches, one of the finest concentrations of rock arches in the eastern United States. It draws hikers, backpackers, and rock climbers from all over the country.
Just beyond the tunnel and the neighboring towns lie some of the Gorge's best-known sights, from soaring natural bridges to overlooks that gaze out across the whole cliff-lined canyon. The tunnel makes a fitting overture: a tight, dim passage through the rock that opens onto a landscape of the very same stone, carved instead by wind and water over unimaginable time.
Driving through Nada Tunnel
Take it slow and take turns. Because only one vehicle fits at a time, the etiquette is simple: stop at the entrance, look all the way through, and if you see headlights coming, wait and let them clear before you go. Switch your own headlights on, since the tunnel is unlit, and mind the low, close ceiling, which means large RVs and trailers should find another route entirely.
There are no services at the tunnel, so fuel up and grab supplies in nearby Stanton or Slade first. On busy fall weekends, when the Gorge fills with leaf-peepers and climbers, expect to queue a little, and bring some patience. Handled with care, driving through Nada Tunnel is one of the small, genuine thrills of a Kentucky road trip, and the perfect way to arrive at the Red River Gorge.
