The Only In Your State website has named Shoshone Falls the "Best Waterfall View" in Idaho. This is the biggest DUH moment in the history of DUH moments. Tell us something we don't know.
Saying that Shoshone Falls is the best waterfall view in Idaho is like saying water is wet. The sky is blue. Breaking news: the Snake River Canyon is the best canyon named after a snake.
I highly recommend you check out the rest of their list which they call "These 10 Jaw-Dropping Views of Idaho Will Blow You Away". Everything on the list is stellar. Actually, Idaho is stellar. Also something we already knew.
