Sully Creek State Park Primitive Road
Forgotten badlands track through pioneer country.
This unmarked two-track cuts through some of North Dakota’s most isolated badlands terrain, following old cattle paths and survey routes that date back to the 1880s homestead era. The road winds through Sully Creek’s carved valleys, past abandoned homestead foundations and windmill ruins, offering genuine solitude in the Little Missouri River drainage. The technical challenge comes at Devil’s Backbone Ridge, where loose shale and narrow shelf road demand patience and precise wheel placement.
Moderate difficulty requires high-clearance 4WD with good ground clearance for rocky creek crossings and muddy gumbo sections after rain. Best tackled May through October when creek levels are manageable. No services for 40 miles in any direction — carry extra fuel, water, and recovery gear. This is pure North Dakota backcountry: endless sky, wind-carved buttes, and the kind of emptiness that reminds you why the pioneers called it the Great American Desert.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle Sully Creek, or do I need a lift?
A stock high-clearance 4WD handles this trail fine under normal conditions. Stock Wranglers and 4Runners are well within spec — no lift required, but you'll want at least 8 inches of clearance for the rougher rutted sections.
Is Sully Creek accessible in early spring or after heavy rain?
Avoid it when wet — the clay-heavy badlands dirt turns into a tire-eating mess after rain and can stay slick for days. Best window is late May through October when the ground is dry; early spring snowmelt makes the trail unpredictable and the crossings significantly deeper.
Do I need a permit to run Sully Creek Primitive Road?
North Dakota State Parks requires a valid vehicle entry pass for Sully Creek State Park — day passes and annual passes are available. No trail-specific permit is needed beyond that, but check current rules with North Dakota Parks before you go as fees and requirements can change.
What's the hardest section of the trail and what should I actually expect?
The tightest challenge comes from eroded clay ruts and off-camber shelf sections through the badlands draws — nothing technically extreme, but loose footing and surprise washouts keep you honest. Moderate doesn't mean boring here; the terrain shifts fast and a dry line can disappear after one bad storm.
Are the water crossings on Sully Creek actually driveable, and is there anywhere to camp along the route?
The crossings are typically shallow enough for a stock high-clearance rig in dry season, but check recent conditions before committing — spring runoff can push depths well beyond what's comfortable. Dispersed camping is available along the route; top off water and fuel in Medora before you head out, because there's zero cell service and no services on trail.
