San Bois Mountains Wilderness Traverse
Coal mining heritage meets extreme mountain terrain.
The San Bois Mountains in southeastern Oklahoma hide some of the state’s most challenging backcountry terrain, where early 1900s coal mining operations carved roads into steep mountainsides that time and weather have turned into technical obstacles. This route follows old mining haul roads through the Ouachita National Forest, climbing ridges where bootleggers once hid stills and descending into creek valleys carved by centuries of runoff. The route’s crux comes at Backbone Ridge crossing, where the old road has washed out into a series of rock ledges and water bars that require careful wheel placement and spotting.
Expert difficulty due to steep grades, loose rock, and multiple creek crossings that can become impassable during spring floods — experienced drivers with modified rigs and recovery gear only. Best season runs June through October when creeks are manageable and the clay-based soil isn’t a slippery nightmare. No permits required, but notify local authorities since this area sees almost no traffic and cell service is nonexistent for miles. You’ll earn access to some of Oklahoma’s most pristine wilderness and gain perspective on the hardscrabble coal mining history that shaped southeastern Oklahoma’s culture.

Frequently asked questions
Can a lightly modded Jeep JK handle the San Bois Traverse, or do I need serious armor?
A lightly modded JK can get into trouble fast here. You need skid plates, rock sliders, and a minimum 2-inch lift with all-terrain tires — the rocky creek crossings and shelf roads will punish unprotected undercarriage. Full armor and a locker are strongly advised for the expert sections.
Is the trail passable in spring, or does the wet season make the creek crossings dangerous?
Stick to June through October. Spring snowmelt and heavy Oklahoma rains turn the creek crossings from challenging to genuinely dangerous, and the clay-heavy soil becomes impassable mud. After summer thunderstorms, wait at least 48 hours before attempting the water crossings.
Do I need a permit to run the San Bois Mountains Traverse?
No permit is currently required to run the trail on Ouachita National Forest land, but dispersed camping is subject to USFS regulations — no fee, but fires must comply with any active fire restrictions. Check current conditions at fs.usda.gov/ouachita before you go.
What's the hardest section of the trail and what should I actually expect?
The upper rocky shelf roads approaching the ridgeline are the worst of it — narrow, loose shale, significant off-camber exposure, and no room for error. The creek crossings below can run 2-3 feet deep depending on recent rainfall, with slick rock bottoms that can shift your line mid-crossing.
How far out is the nearest gas, and is there any water on trail I can rely on?
Wilburton is your last fuel stop — fill up there, as you're looking at 23 miles of hard terrain with zero services. Creek water is present on trail but must be filtered or treated; don't count on it as a guaranteed source since flow varies seasonally.
