Burning Coal Vein Road
Underground coal fire burning since the 1950s
The ground stays warm year-round along this remote badlands track where an underground coal seam has been smoldering since the 1950s. You’ll navigate rough two-track roads through the Little Missouri National Grassland to reach the active burn area near Sentinel Butte, where steam still rises from cracks in the earth and the soil feels hot to the touch. The route follows old ranch roads and cattle trails through some of the most isolated country in southwestern North Dakota, passing through colorful clay formations and scattered homestead ruins.
This is moderate difficulty requiring high-clearance 4WD for the final approach roads, especially after rain when the bentonite clay becomes impossibly slippery. Best tackled April through October when roads are passable. No permits needed but respect private land boundaries and carry extra water—services are 50+ miles away. The payoff is witnessing one of North Dakota’s most unique geological phenomena while camping under some of the darkest skies in the region.

Frequently asked questions
Can a stock Tacoma handle Burning Coal Vein Road?
Yes, any stock high-clearance 4WD truck or SUV can handle this trail. The dirt surface is moderate difficulty with no major obstacles, just rough sections and some steep grades.
Is the trail accessible in winter?
No, avoid winter travel on this trail. Snow and mud make the dirt roads impassable, and services in the area are extremely limited from November through March.
Do I need permits to drive Burning Coal Vein Road?
No permits required. This is public land managed by the Forest Service as part of Little Missouri National Grassland, but follow Leave No Trace principles for dispersed camping.
What's the hardest part of this trail?
The steepest grades near the active coal fire areas where the road climbs 800 feet. Some sections can be rutted and loose, especially after rain, requiring careful throttle control.
How far should I plan for gas range on this trail?
Plan for at least 200 miles of fuel range. Sentinel Butte is tiny with limited services, and you'll want enough gas to explore the 18-mile trail plus get to Medora or Dickinson for reliable fuel stops.
