NameTail of the Dragon
RouteUS 129 · Deals Gap, NC → TN
Length11 mi
Curves318
The original Deal's Gap road.
Eleven miles, 318 curves, no straight longer than a few hundred feet. Runs from Tab Cat Creek at the North Carolina line up to the Calderwood Dam overlook on the Tennessee side. Paved in the early 1990s; a dealer's-tree of photographers has been at both ends since. The Dragon has a fan club, a count-keepers' association, a memorial at the south end for the people who didn't make it, and a $20 "I survived" sticker at the gift shop.
Run it before 9 a.m. on a weekday in October. The surface is grippy, the temperature is fifty, and there is nobody on it.
NameThe Diamondback
RouteNC 226A · Little Switzerland → Spruce Pine
Length12 mi
Curves190
The northern switchback dragon.
Twelve miles, 190 switchbacks, runs from the Little Switzerland Inn down to the North Carolina Mineral Museum at Spruce Pine. Narrower than the Tail, no shoulder, almost no guardrail. The Diamondback is the regional drivers' second favorite — fewer cameras, fewer riders, more commitment. It also has the most spectacular crash record of any road in the state, which is why the Spruce Pine fire department keeps an off-road rescue vehicle stationed at the bottom on weekends.
NameThe Back of the Dragon
RouteNC 226A · From the OTHER side
Length30 mi
Curves147
The longer mountain route.
Often confused with the Diamondback (they share a road number for part of the route) but properly understood as the 30-mile traverse from Rutherford County up through the South Mountains, along a series of long sweepers and short hairpins. Less famous than the Tail, less extreme than the Diamondback, more sustained. This is the road you run when you want thirty minutes of cornering without the tourist traffic of the two above. The default for a long Sunday in a manual M3.
