Iron Mountain Trail: Damascus to Mount Rogers (2026 Appalachian Trail Detour)

Iron Mountain, Flat Top, and Mount Rogers trails, Mount Rogers National Recreation Area, Jefferson National Forest (Damascus to Deep Gap)

The Iron Mountain Trail was the Appalachian Trail north of Damascus until 1972, according to Hiking Project, and in 2026 it is carrying A.T. hikers again. With the A.T. closed between US 58 at Straight Branch and Grassy Ridge Road while the Virginia Creeper Trail is rebuilt after Hurricane Helene, the Appalachian Trail Conservancy signed a 20.9-mile detour on Iron Mountain, Flat Top, and Mount Rogers trails.

It also works as a backpacking trip in its own right: a long ridge walk with old A.T. shelters, finishing on the climb to the Mount Rogers high country.

The hike

The ATC’s detour starts in Damascus on the Iron Mountain Spur and Iron Mountain Trail, which together run 15.3 miles. The trail is yellow-blazed, and Visit Damascus describes it as remote singletrack with ridgeline views. Hiking Project says much of it follows ridgelines through oak forest, with connections to forest roads and the 67-mile Virginia Highlands Horse Trail, and names Shaw Gap, Beartree Recreation Area, Straight Branch, and Sandy Flats as points for planning shorter loops.

The ATC lists three overnight stops with water: Sandy Flats Campsite at detour mile 4.8, Straight Branch Shelter at 9.7, and Cherry Tree Shelter at 15.3. Bikepacking.com calls Straight Branch and Cherry Tree three-walled shelters left from the trail’s A.T. days, and Visit Damascus says three historic shelters remain open for overnight use.

At Cherry Tree the detour turns onto the blue-blazed Flat Top Trail for 1.7 miles to Fairwood Valley, then climbs the blue-blazed Mount Rogers Trail for 3.9 miles to rejoin the A.T. The ATC puts the junction about 2 miles from Thomas Knob Shelter; Visit Damascus places it at Deep Gap. Wikipedia’s Lewis Fork Wilderness article rates the Mount Rogers Trail as difficult, and the upper part runs through that wilderness, where groups are limited to 10.

Expect company. The ATC says to watch for bikes, horses, and some motorized vehicles, and Bikepacking.com reports the trail “gets pretty muddy” after hard rain, mostly in the first few miles at its eastern end. The ATC suggests carrying a paper map, sold at the ATC store and Damascus outfitters.

From the A.T. junction, northbound hikers continue past Thomas Knob Shelter into the high country covered on the Summit Cut to Fox Creek page; the Fairwood Valley and Wilburn Ridge loop uses the same Mount Rogers Trail. South of Damascus, the A.T. heads into Tennessee toward Laurel Fork and Dennis Cove.

Tips

Wear blaze orange during hunting seasons.
Fill up at the shelters. Sources disagree on how dry the ridge stretches are.
Don’t road-walk around the closure. The ATC says Grassy Ridge Road and US 58 have no shoulder, and US 58 carries construction traffic.
Park legally in Damascus. Visit Damascus says long-term parking is at the Wilson Street and Trestle Street lots with registration and a 30-day limit; Wilson Street closes in May for Trail Days.
Line up your exit. Grindstone Campground and its parking are closed for 2026.

Camping

No permit is needed. The ATC lists Sandy Flats Campsite and Straight Branch and Cherry Tree shelters as the detour’s overnight stops, and Visit Damascus says there are “a number of campsites” along the trail. Dispersed camping is allowed on the national recreation area. The Mount Rogers Trail section is in the Lewis Fork Wilderness, where groups are limited to 10. Once you’re back on the A.T., campfires are banned under the 2026 order.

Inside Intel: No camper accounts recommending a specific site on the Iron Mountain Trail were found. Bikepacking.com notes that water is plentiful up to Straight Branch, which makes that shelter a natural place to stock up.
