Sequatchie Valley Railroad Grade
Railroad grade through Tennessee's deepest valley.
The Sequatchie Valley cuts Tennessee like a knife wound, and this abandoned railroad grade follows its length through some of the state’s most dramatic terrain. Built in the 1890s to haul coal and timber from the Cumberland Plateau, the old Tennessee Central Railway roadbed now serves as a rugged trail past towering limestone bluffs and forgotten mining camps. The route parallels the Sequatchie River for miles, passing through tunnels blasted from solid rock and over trestles that offer commanding views of the valley floor 800 feet below the plateau rim.
Moderate difficulty requires high-clearance vehicles for the rockier sections, though much of the grade remains surprisingly intact. Spring and fall provide the best weather and visibility through the hardwood canopy. No permits required, but some sections cross private land – respect posted boundaries. The reward is traveling through Tennessee’s geological wonder while following the path of iron horses that once connected mountain communities to the outside world. Bring a camera for the trestle views.

Frequently asked questions
Can a stock SUV or crossover handle the Sequatchie Valley Railroad Grade?
High clearance is recommended — a stock 4Runner, Tacoma, or Wrangler handles it fine. Low-clearance vehicles like stock Subarus or minivans will scrape on the rougher gravel sections and any washouts. 4WD isn't strictly required but helps if conditions are wet.
When is the trail closed or impassable?
Best season runs March through November. Winter months bring ice and mud that can make the gravel grade slick and unpredictable. After heavy rain in any season, low-lying sections near the valley floor can get soft and rutted — check recent conditions before you go.
Do I need a permit to run this trail?
Portions of the route cross private land, so stay on the established grade and respect any posted closures or gates. There's no fee or formal permit system as of now, but that can change — check with the Tennessee State land manager for current access status before your trip.
What's the hardest section of the trail and what should I expect?
The trail is moderate overall with no extreme technical obstacles, but watch for soft shoulders near the valley floor and overgrown sections where the old railroad bed narrows. The 400 feet of elevation change is gradual — the challenge is sustained rough gravel and occasional debris from the limestone bluffs above, not steep climbs.
Is there water available along the route, and how's cell service?
Cell service is spotty throughout the valley — don't count on it for navigation or emergency calls. Carry a paper map or downloaded offline route. There's no reliable potable water on trail, so bring everything you need for the day; if you're camping dispersed overnight, pack in all your water.
