Caveats
- A year is counted only when the park reported every one of its twelve months; a year still in progress is left out rather than partially added up.
- Yellowstone National Park has a strip of land in Idaho and is not included: the park is entered overwhelmingly through its Wyoming and Montana gates. The National Historic Trails that cross Idaho (California, Oregon, Lewis and Clark, Nez Perce) have no visitation figures of this kind published for them.
- Nez Perce National Historical Park is 38 sites across Idaho, Montana, Oregon and Washington administered as one park, so its visitation total covers the whole park, not only its Idaho sites.
- City of Rocks National Reserve is managed cooperatively by the National Park Service and the Idaho Department of Parks and Recreation.
