Jefferson National Forest Forest Road 106 Iron Mountain Trail
Iron mining heritage along the Tennessee border.
Forest Road 106 traces the spine of Iron Mountain along the Virginia-Tennessee border, following wagon roads that once hauled iron ore to furnaces in the valley below. The route passes several abandoned mine sites from the 1800s, including the collapsed remains of the Damascus Iron Works at mile 6.4, where rusted machinery still lies scattered among the rhododendron. The road maintains a steady grade along the ridgeline, but several creek crossings and eroded sections demand attention, particularly the rocky descent at Straight Branch where flash floods have carved deep gullies across the roadway.
Moderate difficulty requiring high-clearance vehicles, though stock pickups can handle most sections with careful driving. The route stays open year-round but spring mud and winter ice create challenging conditions. No permits needed, and dispersed camping is allowed throughout the national forest. Several reliable water sources along the route, but cell coverage is spotty at best. This trail delivers a perfect blend of Appalachian history and moderate technical driving, with excellent views of Mount Rogers Wilderness and opportunities to explore dozens of old mining sites.

Frequently asked questions
Can a stock Tacoma or 4Runner run FR 106 without modifications?
Yes — the minimum is high-clearance 2WD, so a stock Tacoma or 4Runner handles it fine. 4WD helps on wet dirt sections and the rockier stretches, but it's not a requirement if conditions are dry.
When does FR 106 typically open and close for the season?
Best window is May through November. Snow and mud can make the trail impassable in winter, and Jefferson National Forest may gate certain forest roads after heavy weather or during fire closures — check with the Mount Rogers National Recreation Area office before you go.
Do I need a permit or pay any fees to drive FR 106?
No permit or fee is required to drive or camp dispersed on this forest road. Standard Jefferson National Forest dispersed camping rules apply — stay 150 feet from water, roads, and trails, and pack out everything.
What's the hardest section of the trail and what does it actually involve?
The roughest terrain is on the rockier ridge sections where embedded rock and loose stone can be uneven underfoot for your tires. Nothing technical enough to require a locker, but a few spots will drag a low-clearance vehicle — take them slow and pick your line.
How far is the nearest gas from the trailhead, and is there water on the trail?
Damascus, Virginia is your last reliable fuel stop — fill up there before heading out, as you're looking at a full day with no services on trail. There are water crossings on the route, but treat or filter any water before drinking; don't count on it as your primary source without a filter in your kit.
