Kootenai Falls

Kootenai Falls is the largest undammed waterfall in Montana, a thundering series of cascades where the Kootenai River drops 90 feet through a granite gorge in less than a mile. The sheer volume of water is staggering — the entire river, one of the major tributaries of the Columbia, compresses through the narrow canyon and detonates over multiple ledges in an explosion of whitewater and spray. The force is so great that the mist rises like smoke above the forest canopy.

No real hiking is required — a short half-mile trail from the parking area leads through forest to multiple viewpoints along the canyon rim. A swinging suspension bridge crosses the gorge downstream, offering vertiginous views of the churning river below. The bridge sways noticeably in the wind and under foot traffic, adding an adrenaline element to the visit. Stairs descend to river-level platforms for close-up views of the cascades.

The falls run powerfully year-round, but spring runoff from April through June produces the most spectacular flows. The site is sacred to the Kootenai Tribe and featured in the film The River Wild. Free access with no entrance fee makes this one of the best waterfall values in the Northern Rockies.
