Missouri River Confluence Backcountry Trail
Remote river confluence technical challenge
Where the Yellowstone dumps into the Missouri near the Montana line, this gnarly backcountry trail drops through cottonwood bottoms and climbs chalky bluffs that Lewis and Clark sketched in their journals. The 18-mile route requires serious clearance to navigate washouts, fallen timber, and creek crossings that turn into axle-deep mud traps when the rivers run high. Buford trading post ruins and old homestead foundations emerge from prairie grass like ghosts.
Difficult rating demands high-clearance 4WD with skid plates and recovery gear — this isn’t weekend warrior territory. Spring flooding makes sections impassable until July, and you’ll want low-range gearing for the steep riverbank climbs. No services for 40 miles, so carry extra fuel, water, and repair supplies. The payoff is pristine river country where eagles nest and you might not see another human for days. Come prepared or stay home.

Frequently asked questions
What kind of vehicle do I need for Missouri River Confluence Trail?
You need a high-clearance 4WD with skid plates minimum. Stock trucks will take a beating on the rocky sections and water crossings.
Can I run this trail in spring or fall?
Best season is July through September when water levels are lowest. Spring runoff makes crossings dangerous and fall weather can turn the trail into a muddy mess.
Do I need permits from the Army Corps of Engineers?
No special permits required, but you're on Corps land so follow standard regulations. Dispersed camping is allowed but practice Leave No Trace.
How technical are the hardest sections?
The river confluence area has loose rock shelves and steep approaches that'll test your line choice. Water crossings can be tricky with shifting gravel bottoms.
How deep are the water crossings?
Crossings vary seasonally but expect knee-deep water in summer with rocky bottoms. Scout first - the current is stronger than it looks and gravel shifts.
