Great Falls of the Missouri drops 87 ft (27 m) as a block waterfall in Montana.
The falls are fed by Missouri River. It lies in Cascade, Montana. The site is on public land managed by Lewis and Clark NHT / NorthWestern Energy dams.
This is a roadside waterfall: visible from a road, parking area, or a walk of a few hundred feet. The walk to the main viewpoint runs about 0.3 miles round trip. The nearest town is Great Falls.
When to go: Variable (dam-controlled flow). Like most waterfalls, Great Falls of the Missouri runs highest after snowmelt or heavy rain and can thin out in late summer, so it's worth checking recent streamflow and the land manager's conditions page before a long drive.
