A train nicknamed Tweetsie once chugged through the hills of East Tennessee, and its old path now carries walkers, runners, and bikes instead. I love that the railroad builders did the hard work of leveling the land more than a century ago.
Trains hate steep hills. That simple fact is why old rail beds stay flat, gentle, and easy on your knees, even when the scenery around them looks like a postcard.
So when the leaves turn red and gold this fall, you can skip the sweaty switchbacks. You can stroll under a canopy of color with a coffee in hand, a stroller in front, or a dog trotting beside you.
The best part? These five trails cost nothing to enjoy.
I can’t think of a better reason to grab a jacket and go see what those old train tracks left behind.
1. Tweetsie Trail Trailhead
Railroad fans might know the old East Tennessee and Western North Carolina Railroad by its nickname, Tweetsie. Today that historic corridor is a public rail-trail where the only thing chugging along is you.
Your starting point sits at the corner of Legion Street and Alabama Street in Johnson City. From there, the wide crushed gravel path runs with a low, gradual grade that never asks you to climb.
Shade is the big fall bonus here. Dense trees line much of the route, so autumn turns the trail into a long tunnel of color overhead.
Keep an eye out for the overlooks, too. Several good stopping points open up views across the mountain valley, which feels like cheating when you barely broke a sweat getting there.
Mile markers help runners and walkers track their distance without a fancy watch. Historical markers along the way share bits of the railroad story, so your stroll doubles as a mini history lesson.
Families will appreciate that the surface is stroller-friendly. Dogs are welcome outside on the trail, and a porta potty sits near the trailhead for quick stops.
A quick heads up on parking. The lot is free, but it’s small, so arriving early on a crisp fall weekend is a smart move.
Road crossings pop up throughout the route, so stay alert at those spots. The trail opens at 6 AM daily, perfect for catching morning light on the leaves in Upper East Tennessee.

2. The Cumberland River Bicentennial Trail
Bald eagles and ospreys don’t need a trail map, but they seem to know a good river when they see one. Both birds show up throughout the year along this paved greenway in Ashland City.
Seven miles of trail follow the Cumberland River on the bed of the old Tennessee Central Railroad. That railroad history means you get a route with little to no incline from start to finish.
Fall paints the scene in layers. Hardwood trees crowd the river bluffs, and wetland views add even more color to soak in as you go.
Bridges are part of the fun here. The route includes the historic Centennial Trail Railroad Bridge, a reminder that trains once rolled across the same spot you’re crossing on foot.
Want a reason to come back after the leaves drop? Waterfowl settle in during winter, and wildflowers brighten the path in spring.
The paved surface works well for walkers and bikers alike. Restrooms are available, and dogs are welcome outside, so the whole crew can tag along.
Parking is free, and so is access to the trail. From Nashville, it makes an easy Middle Tennessee escape that feels miles away from city traffic.
Bring binoculars if you have them. Spotting an eagle over the water while orange leaves drift down might be the best free show around.

3. Eureka Trail
Eureka is a fitting name for a trail that feels like a lucky find. Runners especially love the crushed stone surface, which makes for a smooth, forgiving stride.
Underfoot is the old Louisville and Nashville railroad bed, which once linked Athens and Englewood. Thanks to that rail history, the grade stays level and friendly for nearly any fitness level.
Horseback riders share the route too, which you don’t see on many trails. Add walkers, runners, and cyclists, and this path becomes a true multipurpose spot.
So what about the leaves? Deeply shaded forest sections and surrounding rural woodlands put on a colorful autumn show in Southeast Tennessee.
That same shade pays off in early fall, when the afternoons can still feel like summer. You’ll stay cooler under the canopy while the trees slowly change color.
Recent upgrades added a parking lot and a restroom building at the Athens entrance. The entrance is well marked, and the lot offers plenty of room.
Athens Parks maintains the trail, and there’s no entrance fee. Dogs are welcome outside, so your four-legged buddy can join the leaf hunt.
Plan around the hours, which run from 7 AM to 9 PM daily. It sits within an easy drive of Chattanooga and Knoxville, making it a simple Saturday plan.
Address: 1400 E Madison Ave, Athens, TN 37303
4. Clarksville Greenway
Swings on a greenway? Yes, and they might be the best seats in the house when the trees start turning.
Clarksville built this 4.6-mile asphalt path along a former railway. The result is a smooth, flat route that gives you real distance with zero mountain drama.
Skaters can roll here alongside walkers and cyclists. The paved surface and cycling lanes make it easy for wheels of many kinds.
Peaceful wooded corridors are the star in autumn. Dense trees wrap around the path, and scenic river views open up along the way.
Keep your eyes peeled for wildlife. Deer show up along the trail, so a quiet morning walk could come with a surprise guest.
Kids get plenty of perks too. A playground, picnic tables, and kid-friendly stretches of trail make it an easy family outing.
Pack lunch and claim a picnic table under the changing leaves. Public restrooms and benches mean you can take your time without rushing home.
Bridges cross the route at several points, adding a little extra charm to the stroll. Dogs are allowed, and the parking lot is free.
Timing matters here, since the greenway is open from 6 AM to 6 PM. Mornings tend to be busiest, so an afternoon visit in northern Middle Tennessee may feel calmer.

5. Mountain Goat Trail
Here’s a funny twist for you. A trail named after a mountain goat turns out to be one of the easiest rides on the Cumberland Plateau.
The name comes from the old Mountain Goat Railroad, which once worked its way across the South Cumberland Plateau. Today, its rail bed carries a paved path that skips the rugged bluffs entirely.
You get the high plateau scenery without hauling yourself up a cliff. Sounds like a fair trade, right?
Plateau woods and tall tree canopies frame the route. In fall, those trees deliver the kind of color people usually drive deep into the mountains to see.
The paved stretch runs around five miles, connecting communities like Monteagle and Tracy City. It’s a favorite for biking, and walkers find it just as pleasant.
Accessibility is a big plus. The smooth surface opens the plateau to folks who might not tackle a steep, rocky hike.
Here’s a rare perk: the trail is open 24 hours a day. Early risers can catch sunrise light on the leaves before most people finish breakfast.
Access is free, and dogs are welcome outside. Sewanee sits about halfway between Nashville and Chattanooga, so it works as a day trip from either city.
Pick a quiet weekday morning for a peaceful ride. Then you can brag that you conquered a mountain goat trail without breaking a sweat.
Address: Sewanee, TN 37375
