Where the Missouri River cuts through central Montana, the Upper Missouri River Breaks National Monument unfolds a vast backcountry of stark white cliffs, eroded badlands, and grassy benches. Managed by the Bureau of Land Management, this remote preserve safeguards a historic river corridor that transported Lewis and Clark, fur traders, and steamboat captains. Today, the monument offers solitude, wildlife viewing, and a rare chance to float or camp along a stretch of river that has changed little in centuries.
Best season — Late spring through early fall, when river levels support paddling (typically May through early July) and the weather allows comfortable hiking and camping; September and October bring mild temperatures and fewer bugs.
