Missouri River Breaks Backcountry Road
Lewis & Clark's route through America's last frontier
The Missouri River Breaks stretch for 149 miles of untamed river corridor where Lewis and Clark described the landscape as ‘scenes of visionary enchantment.’ This network of two-track ranch roads and BLM routes winds through coulees, sandstone formations, and prairie that looks identical to 1805. The main route follows the old Fort Benton to Jordan stage road, passing abandoned homesteads and the same white cliffs that stopped the Corps of Discovery cold. Primitive roads branch off to overlooks above the Missouri, where you might spot bighorn sheep on the bluffs.
Most routes are suitable for stock high-clearance vehicles in dry conditions, but spring mud and flash floods can strand you for days. Late spring through early fall offers the best access, though summer heat hits 100°F regularly. No permits required on BLM sections, but respect private ranch gates. Cell service is nonexistent, and the nearest fuel is often 50+ miles away. Pack serious water and emergency supplies — this is genuine middle-of-nowhere Montana where help isn’t coming quickly.

Frequently asked questions
Can a stock pickup truck handle this trail?
Yes, high-clearance 2WD vehicles can complete the route. The dirt road is maintained but watch for washouts after heavy rains and loose gravel on steep sections.
Is the trail passable in winter?
The route is officially closed November through April due to snow, ice, and impassable mud conditions. May through October is the only reliable access window.
Do I need any permits to drive the Missouri River Breaks?
No permits required for the backcountry road itself. BLM manages the area as public land with free access and dispersed camping allowed.
What's the toughest section of the 89-mile route?
The descent into and climb out of the Missouri River valley has the steepest grades and loosest surfaces. Take it slow on the switchbacks to avoid sliding off the narrow road.
How far can I go without cell service or gas?
Zero cell coverage for the entire 89 miles, and no services between Fort Benton and the eastern exit. Carry extra fuel, water, and emergency communication device.
