Red River Gorge Geological Area
3451 Sky Bridge Rd (Gladie Visitor Center)
Slade, KY
A Kentucky canyon carrying more natural stone arches than anywhere else east of the Mississippi, and a fight in the 1960s that saved it from being flooded.
Kentucky is not the first place most people picture when they think of natural stone arches. The Red River Gorge changes that. Tucked into the Daniel Boone National Forest, this canyon of Corbin sandstone holds more than a hundred natural arches, the greatest concentration anywhere east of the Mississippi River, along with towering cliffs, hidden rock shelters, waterfalls, and narrow ravines. It was named a National Natural Landmark in 1975, and it has become one of the top rock-climbing destinations in the world.
The arches are the work of slow, patient erosion. Wind, water, and the endless freeze and thaw of Kentucky winters wore away softer sandstone while a harder cap rock held on above, leaving graceful spans of stone standing in the forest. The same rock shows off vivid bands of red, orange, and brown, iron-rich patterns left by groundwater moving through it over ages. What almost happened to all of this, and the fight that stopped it, is a story worth knowing before you go.
What Guests Love
- More than a hundred natural sandstone arches, the highest concentration anywhere east of the Mississippi River
- Clifftop overlooks like Chimney Top Rock with sweeping views out over the whole gorge
- Driving through Nada Tunnel, the tight, one-lane former railroad tunnel that serves as the gateway into the gorge
- World-class rock climbing on featured sandstone cliffs that draws climbers from around the world
Worth Knowing
- Many trails lead to clifftops and arch tops with unguarded, railing-free edges; stay back from the edge, walk the center of arch tops, and keep a close eye on kids and pets, since falls are the leading danger here
- Nada Tunnel is one-lane, narrow, and unlit, so turn on your headlights, check that the way is clear, and take turns with oncoming cars
- Popular trailhead lots like Chimney Top Rock and Gray's Arch fill early on peak-season weekends, so arrive early, and note that some sites have vault toilets and no running water
- Check current parking and permit rules at the Gladie Visitor Center or on recreation.gov before you go, and pack water and plan fuel and food ahead, since services inside the forest are limited

How the arches came to be
The arches are carved from Corbin sandstone, a hard, resistant rock laid down long before the dinosaurs. Over immense stretches of time, wind, rain, and the repeated freezing and thawing of water in cracks pried away the softer, weaker sandstone. Where a harder cap of rock protected the stone beneath it, the erosion left a span standing, and over more than a hundred of these formed across the gorge, from small windows to broad walk-across bridges of stone.
The rock itself is beautiful up close. Groundwater moving through the sandstone over the ages redistributed iron-rich minerals into striking bands and swirls of red, orange, and brown. People have lived among these cliffs for a very long time, too: archaeological evidence in the rock shelters goes back more than twelve thousand years, and the gorge is cited as one of the earliest places in eastern North America where people began to domesticate plants.
The dam that almost drowned the gorge
In 1962 a devastating flood tore through Clay City, and in its wake officials approved and funded a flood-control dam that would have backed water up and drowned much of the gorge under a reservoir. For a time it looked inevitable. The Sierra Club helped organize the opposition and recruited a powerful ally: Justice William O. Douglas of the United States Supreme Court, a committed conservationist, who came to Kentucky and hiked the gorge to draw the nation's attention to what would be lost.
That famous protest hike, in November 1967, brought Douglas and hundreds of supporters into the canyon and turned a local dispute into a national cause. The fight dragged on for years until Kentucky's governor withdrew state support for the dam in 1975. The door finally closed for good in 1993, when a nineteen-mile stretch of the Red River was designated a National Wild and Scenic River, protecting it permanently. The arches, the cliffs, and the river you can visit today are here because people fought to keep them.
Arches, overlooks, and a famous tunnel
There is far more to see than anyone can manage in a day. Sky Bridge is a large arch you can walk across, reached by a short loop. Gray's Arch is a dramatic span at the end of a longer hike. Princess Arch is a smaller, elegant one that shares a trailhead with Chimney Top Rock, a clifftop overlook with sweeping views over the gorge. Rock Bridge is the only arch in the gorge that spans flowing water, arching over a creek near a waterfall. The most famous arch of all, Natural Bridge, stands in the adjacent state park just to the south.
The gorge has its own front door, and it is unforgettable. Nada Tunnel, a former logging-railroad tunnel bored through the rock between 1910 and 1912, is about nine hundred feet long, one lane wide, and unlit. Drivers take turns easing through the tight, dark passage, and it has earned its nickname as the gateway to the Red River Gorge. The Gladie Visitor Center, on the scenic byway that links these sights, is the place to get oriented, with exhibits on the gorge's geology, wildlife, and human history.
A world capital of climbing
Beyond the hikers and the sightseers, the Red River Gorge is one of the great rock-climbing destinations on earth. The featured sandstone cliffs hold thousands of routes for every level of climber, and on a good weekend the parking lots fill with people from all over the country and the world who have come just to climb here. It is the kind of place where a traveler passing through can watch climbers work a wall high above a trail and feel the pull of the sport even without ever tying in.
The climbing community has given the area its own culture, and it is welcoming to visitors of every kind. Whether you come to hike to an arch, drive the scenic byway, stand on a clifftop overlook, or just ease your car through Nada Tunnel, the gorge rewards the same thing it has always rewarded: slowing down, looking closely, and treating a wild and hard-won place with the care it deserves.
