National Park Service Sites in Idaho
The Bumblie Climbing Area in the City of Rocks National Reserve
So much of Idaho is tied up in some truly incredible wilderness areas that there isn't a lot left over for National Parks. But several of the big emigrant trails from the 1800's cross the state.
I'm including the Bear River Massacre National Historic Site here because it is a registered National Historic Site. However, the property is owned by the Shoshone Tribe and is not under the jurisdiction of the National Park Service. It commemorates the massacre of hundreds of Native American men, women and children at the hands of the California Volunteers who occupied Utah during the Civil War. The Volunteers were there to ensure that Utah's Mormons remained "loyal" to a country that had essentially killed their leaders, stole their property and chased them out to the very edge of civilization.
