Little Missouri River
Arkansas
The Little Missouri River begins in western Arkansas southeast of Mena, flowing freely through the Ouachita Mountains and scenic areas of the Ouachita National Forest that include the Little Missouri Falls and Albert Pike recreation areas.

The river is also designated as an “Arkansas Natural and Scenic River” by the state.
