Paddling in Theodore Roosevelt National Park

The Little Missouri River is the water that defines paddling at Theodore Roosevelt National Park.

It's a low-gradient, meandering river cutting through the North Dakota Badlands — long sigmoid bends, cottonwood bottoms, and buttes rising sharply from the valley floor. This is not whitewater country.

It's Class 1 flatwater through one of the more remote and visually striking landscapes in the Great Plains, and the river's character is shaped almost entirely by snowmelt and spring rain. The window for floating is narrow.

May and June are the reliable months. River ice typically breaks up by early April, but by July the Little Missouri is shallow and braided with sandbars — some years it never reaches floatable depth at all. The park considers 2.

5 feet (roughly 699 cfs at the Medora gauge) the minimum for reasonable boating. Below that, you're dragging more than paddling. Check the USGS gauge before you commit to anything.

The anchor run is the multi-day float from Sully Creek State Park, just south of Medora near the South Unit, downstream through the park to Juniper Campground in the North Unit — about 107. 5 miles to Long X Bridge on U. S. Highway 85. Plan on five days.

Groups averaging this stretch typically paddle around six hours a day. The takeout at the Highway 85 bridge involves hauling boats up a steep bank; bring rope and a second person above.

From Long X Bridge, two more days carry you to Lost Bridge on State Highway 22 at Little Missouri Bay on Lake Sakakawea, but that lower stretch is less scenic than the park corridor.

For a single day on the South Unit, the put-in at Sully Creek to the takeout at Cottonwood Campground is the standard run — roughly four to six hours depending on stops, with sandbars to negotiate even in good water years.

In the North Unit, Juniper Campground to the Highway 85 bridge is the go-to day trip, though that steep takeout applies here too.

Shuttle logistics are real: the river runs south to north, the distances are long, and there's no commercial infrastructure inside the park. Bring your own canoe or kayak. The park recommends canoes or kayaks specifically — no motors, no inflatables implied.

Weather demands attention; summer thunderstorms can push water levels up fast with almost no warning, turning a quiet float into something else entirely. The Little Missouri doesn't reward impatience or poor timing.

Get it right and you have days of solitude in badlands terrain that most park visitors never reach on foot.
