Based on this listing's approximate location — see the note on coordinates below.
Myrtle Falls is a 100-foot waterfall accessed via a half-mile trail within the Kootenai National Wildlife Refuge near Bonners Ferry. The U.S. Fish & Wildlife Service manages the trail system, which offers a blend of accessible and backcountry exploration.
The first 0.15 miles of the trail is paved and fully ADA accessible, providing wheelchair and stroller access to a bridge viewpoint. Beyond the bridge, an additional 0.1 miles of steeper unpaved trail leads to an overlook with closer waterfall views. This design allows visitors of varying abilities to experience the site at a level suited to their comfort and mobility.
The trail continues into the adjoining Idaho Panhandle National Forest. No day-use fee is required, and the refuge setting provides opportunities to observe native wildlife and forest ecology. The waterfall is particularly impressive during spring and early summer when snowmelt boosts water volume. The combination of accessibility infrastructure and natural setting makes Myrtle Falls a relatively unique destination that accommodates both ADA visitors and those seeking more challenging terrain.
Year-round; paved section accessible in all seasons.
