About Castner Falls
Castner Falls sits on the Missouri River in Montana as one of the cascades in the series commonly known as the Great Falls of the Missouri. Nestled in rugged, rocky terrain, the falls offer picturesque river views that reward hikers and photographers who make the short journey out to the water’s edge. The setting feels wild and scenic rather than developed, making it a great stop for those who enjoy raw river landscapes and short day outings. Access to Castner Falls is on county-owned land (land owner: CNTY) listed as a Local Other or Unknown land unit, with the managing agency recorded as unknown (Manager: UNKL). Because formal facilities and management details are limited, expect informal access points and minimal services—plan ahead, pack out what you pack in, and respect any local restrictions or private-property boundaries.
The Setting
Castner Falls sits at 3,543 feet within Local Other or Unknown, fed by the Smith River, in the mountains of Montana.
