Devil's Triangle (TN-116)
A roughly 44-mile loop northwest of Oak Ridge on TN-116, TN-330, and TN-62, with switchbacks and steep dropoffs through old coal-country ridges. The mapped route follows TN-116, the loop's signature technical leg from Oliver Springs over Petros and Briceville to Rocky Top.
What you'll hit along the way.
Rider-verified stops, overlooks, fuel, and the corners worth knowing about — in the order you'll meet them.
Oliver Springs
Traditional starting point at the south end of TN-116 — fuel and food here, as services are scarce on the loop itself.
Petros
Small community below Frozen Head State Park, known for the former Brushy Mountain State Penitentiary, now open for tours.
Briceville
Coal camp hamlet on the New River stretch — the tightest switchback section lies on the ridge between Petros and here.
Rocky Top
Northern end of TN-116 at the town formerly called Lake City — fuel and food near the I-75 interchange to close the loop via TN-62.
