Devil's Triangle: a legendary Tennessee motorcycle route

Located just northwest of Oak Ridge, the Devil’s Triangle works its way through the rough topography of the Cumberland Plateau. The route is a 44-mile loop consisting of three East Tennessee roads: Highways TN-62, TN-116, and TN-330. While there’s no official starting point, many motorcyclists begin at the TN-62 and TN-116 intersection and ride clockwise. This direction allows you to take the curviest parts of TN-116 going uphill, which is especially helpful around the diabolical Armes Gap.

Experienced riders often enjoy tackling the loop in both directions, making it a versatile challenge and, potentially, an all-day ride.

If you’re just riding the triangle, the 44-mile route will take around two to three hours. Adding stops along the way can extend this ride into a weekend adventure. Use the interactive map to help you plan.

From December to March you could see snow on the route, so most riders prefer visiting between April and November. The best riding seasons are mid-May to late June, and late August to early October—when the fall foliage is at its peak. July often brings heavy rain, with an average of 5.6 inches, so riders typically avoid that month.

Always check the local weather forecast before heading out and dress for the ride accordingly. Here are the average monthly temperatures in Oak Ridge, TN.

While thrilling, the Devil’s Triangle presents some challenging terrain for novice riders. The route’s tight turns, steep drop-offs, and sharp switchbacks can feel intimidating and demand your full attention. Make sure your brakes are in excellent condition.

Along TN-116, you’ll pass rural homes and might share the road with kids on ATVs. The route may also be populated with coal trucks and other motorcyclists, so ride within your comfort zone and stay alert.

Though relatively short, the Devil’s Triangle has several must-see, famous stops worth a visit:

Once the prison of James Earl Ray, who assassinated Martin Luther King, Jr., this historic penitentiary opened in 1896 and operated until 2009.

Known for its mineral springs and coal mining history, Oliver Springs was founded in 1821 as a coal mining town. Today, its expansive fields house popular off-road trails. Highlights include:
