Moyie Falls is a tiered waterfall on the Moyie River in Boundary County, Idaho, at about 1,936 feet elevation. Set within a rocky canyon, it drops roughly 85 feet in total through two main sections. Its upper plunge passes beneath an obsolete bridge spanning the gorge, with estimates for that drop varying from 60 to 100 feet, while the lower section falls another 20 to 40 feet. The falls are especially notable for the dramatic combination of a narrow canyon, a stepped descent, and the old bridge overhead.
