Explore one of the largest waterfalls (by volume) in Montana and the Pacific Northwest. The falls can also be seen in the movies "The River Wild" and 'The Revenant".
Kootenai Falls is accessed via short dirt trail from the parking lot on Highway Two between Troy and Libby. In the summer the parking lot is often full and even has some vendors selling objects and food.
The trail is easy to follow and winds through the forest before descending towards the river, with numerous viewpoints and benches along the way. You will also cross a pedestrian walkway over the railroad tracks (the trains do run frequently).
Once at the river you can walk among the rocks upstream for a little ways. The amount of exploring is mostly determined by water flow, during runoff or periods of high water the Kootenai should NOT be tested. During periods of lower water more rocks are exposed and you can explore a bit more. At all times be careful as the river is deceptively fast and downstream lies several smaller rapids and large rocks that could make a swim really unpleasant.
To see the swinging bridge (Kootenai Suspension Bridge) simply head back toward where you came from on the Kootenai Falls Trail. You will see the "Swinging Trail" branching off to your right. Take this trail and you'll quickly see the bridge. Once you're ready to head back to your car, simply head back to the junction with the Kootenai Falls Trail and head back toward the parking area.
