The Tail of the Dragon is an 11-mile stretch of US 129 that runs from Deals Gap on the North Carolina line north into Tennessee, and it is credited with 318 curves in those 11 miles. The speed limit is 30 mph, it is enforced hard, and vehicles longer than 30 feet are banned outright on the Tennessee side. There are no houses, no driveways and no gas along it, because most of the road forms the southwestern boundary of Great Smoky Mountains National Park. That combination — relentless corners, zero cross traffic, and a police presence that has grown every year since 2007 — is why riders plan whole trips around eleven miles of asphalt.
What the road actually is
US 129 crosses Deals Gap at 1,988 feet on the North Carolina–Tennessee state line, in the Great Smoky Mountains. The community that shares the name sits 0.7 miles south of the gap where US 129 meets NC 28. North of the gap, the road carries the name Calderwood Highway in Tennessee; south of it, Tapoco Road in North Carolina. The whole thing is signed as US 129, with a hidden state designation of SR 115 on the Tennessee side.
The nickname dates to 1981. The sharpest corners picked up names of their own along the way — Copperhead Corner, Hog Pen Bend, Gravity Cavity, Brake or Bust Bend, Wheelie Hell, Beginner's End. Riders use them the way climbers use pitch names, and if someone tells you they got loose at Gravity Cavity, that is a specific place, not a mood.

Riding it, north to south and back
Most riders base at the south end and run north first. The Tennessee half stacks its tightest work early: blind, decreasing-radius corners with rock on one side and a drop on the other, and a surface that changes grip in the shade. The middle stretch opens into slightly longer bends where you can carry a gear higher. Coming back south, the same corners read completely differently — camber that helped you now works against you, and the sightlines that felt generous northbound close up.
That is the reason people ride it repeatedly rather than once. Nobody learns 318 corners in a single pass. The riders who look smooth on the Dragon have usually done fifty laps over several years, and they are still riding well inside their limit, because the road punishes optimism with rock walls.
The 30 mph problem
The limit was 55 mph before 1992 and was cut to 30 mph in 2005. Enforcement on the Tennessee portion has increased sharply since 2007, and it is not theatre — unmarked cars, radar in the pull-offs, and officers who have seen every excuse. Crossing the center line is the ticket most riders collect, and on a road this narrow the center line is exactly where a fast entry puts you.
The other reason to keep it sane is response time. Blount County Rescue Squad staffs the Dragon on summer weekends specifically because ambulance service dispatches from Maryville, and getting a crew to a wreck in the middle of the 11 miles can take more than an hour. About 37 people died on this stretch between 2000 and 2017. That number is not there to scare anyone off; it is there because riders routinely underestimate how far from help they are while sitting eleven miles from a gas station.
Trucks, and why the ban matters to you
North Carolina moved first, in 2012, banning trucks with trailers longer than 30 feet on US 129 from the Graham/Swain county line at Cheoah Dam to the state line, on NC 28 from NC 143 to US 129, and across the entire North Carolina portion of the Cherohala Skyway. Tennessee followed in 2015 after a rider was killed by a semi at mile marker 6, and the Tennessee rule is broader: no vehicle over 30 feet and no trailer over 30 feet, single units included. North Carolina's version exempts single vehicles like RVs; Tennessee's does not.
The Tennessee Department of Transportation still publishes the restriction in its weekly East Tennessee construction reports, which tells you the enforcement is live and the problem is not solved. Trucks still turn up, usually because a GPS routed them through as a shortcut. If you meet one, it will be across both lanes. Ride the Dragon assuming that at least one vehicle per lap will be somewhere it should not be, and your entry speeds sort themselves out.
The practical details
Fuel. Nothing on the 11 miles. Fill up in Robbinsville, Fontana Village or Maryville before you start, and treat the Deals Gap end as your turnaround rather than a resupply.
When to go. Weekday mornings, early. Weekends in spring and fall bring car clubs, sightseers and photographers, and a slow line of traffic on this road is more dangerous than an empty one because of what people do to get past it. A driver swinging out to overtake has usually stopped seeing whoever is behind them, which is exactly what our blind spot guide deals with. Winter brings ice and salt brine in the shaded corners even when the valleys are dry.
Surface. Leaves, gravel washed out of the cuts, and damp patches that stay damp all day under tree cover. Rain turns the Dragon into a completely different road — the tar snakes and painted lines go slick immediately.
Nearby roads worth the trip. The Cherohala Skyway, NC 28 (the Hellbender), and the Foothills Parkway are all within an easy ride, and all three are faster, longer and less crowded. Most people who ride the area for a week spend one morning on the Dragon and the rest on those. Anyone carrying on east across the national park picks up the Blue Ridge Parkway at Cherokee, where its southern end sits.
Gear notes for the Dragon
Two things matter more here than on a normal road. First, tires. Eleven miles of constant direction change works the sidewalls hard and heats the carcass fast, and a cold morning start at 1,900 feet followed by six laps means your pressure at lap five is nowhere near what your gauge read in the parking lot. We explain what six hard laps do to your tire pressure, and a TPMS sensor puts the number in front of you between laps instead of after the fact. We build these, so weigh that as you read.
Second, video. This is the most photographed motorcycle road in the country for a reason: things happen here, and they happen to riders who were doing everything right when a truck or a distracted driver came across the line. A forward and rear camera running the whole time is the cheapest insurance on the road, and having it built into a riding system display means it is recording before you remember to think about it. The JADO S6 handles both jobs — dual cameras plus live tire data on one screen — which keeps the bars clear of the clutter you do not want on a road with this little runoff.
FAQ
Is the Tail of the Dragon really 318 curves in 11 miles?
That is the count that has been attached to the road since it got its name in 1981, and it is what the Tennessee stretch is described as having. Nobody re-surveys it, but the number is close enough that the road feels exactly like the claim.
Where does the Tail of the Dragon start and end?
It runs along US 129 between Deals Gap on the North Carolina–Tennessee state line and the Tennessee end near Chilhowee, with the state line crossing at 1,988 feet. Deals Gap itself is where US 129 meets NC 28.
What is the speed limit on the Dragon?
30 mph for the full 11 miles. It was 55 mph until 1992 and dropped to 30 mph in 2005, and the Tennessee side is patrolled heavily.
Are trucks allowed on the Tail of the Dragon?
No. Tennessee bans any vehicle or trailer over 30 feet; North Carolina bans trailers over 30 feet on the approaches, including all of its portion of the Cherohala Skyway. You will still occasionally meet one that ignored the signs.
Is it a good road for a beginner?
It is a poor place to learn cornering. There is no runoff, no cell coverage worth counting on, and emergency response can take an hour. Newer riders do far better on the Cherohala Skyway first, then come back to the Dragon at a pace that leaves margin.
