Sequoyah County Iron Ore Railroad Grade Heritage Trail
Iron ore railroad grades through the Cookson Hills
The rusted rails are long gone, but the railroad grades carved into Sequoyah County’s Cookson Hills tell the story of Oklahoma’s forgotten iron boom. This 18-mile route follows the old Missouri Pacific spur that hauled red ore from mines near Marble City to the Arkansas River loading docks. You’ll cross Sallisaw Creek on the original stone bridge abutments and wind through second-growth oak where mine shafts once dotted the ridges.
Moderate difficulty with a few technical creek crossings and one steep climb over Sugarloaf Mountain. Stock 4WD handles it fine, but low-range helps on the loose shale grades. Spring and fall offer the best conditions—summer gets muggy in the bottomland, winter turns the clay slick as snot. No permits needed on this mix of county roads and old railroad right-of-way. You’ll find decent camping spots near the old Marble City depot site, plus a real education in how mining shaped eastern Oklahoma before oil took over.

Frequently asked questions
Can a stock 4Runner or Wrangler handle this trail without modifications?
Yes, a stock 4WD with decent clearance is the listed minimum and should be fine for the railroad grade surface and moderate terrain. Aired-down tires help on the softer dirt sections, especially after rain.
When does this trail get muddy or impassable?
Winter and early spring (December through March) can turn the dirt grades into a slick mess after rain or snow. Stick to April-May or October-November when the surface is drier and the Cookson Hills are at their best.
Do you need a permit to run this trail or camp here?
No permit is required — the trail is managed by Sequoyah County and dispersed camping is allowed. No fees as of current information, but check with the county if anything has changed before you go.
What's the hardest section and what should I actually expect?
The water crossings are where this trail shows its teeth — depth and flow vary significantly with recent rainfall, so scout before you drive. The climbs along the old iron ore grades aren't technical, but loose dirt and off-camber sections keep you honest.
How far is the nearest gas from the trailhead, and is there cell service on route?
Sallisaw is your last reliable fuel stop before hitting the trail, so fill up there — it's the nearest town. Cell service is spotty throughout the Cookson Hills, so download offline maps and don't count on data when you need it most.
