National parks in Idaho

Every national park and public-land unit in Idaho, scored and ranked by our Experience Score.

Idaho has three National Park Service units. Craters of the Moon National Park, in the central Snake River Plain, features a volcanic landscape. This terrain attracts stargazers and hikers. To the north, Nez Perce National Historical Park is spread across multiple locations. It focuses on Indigenous and frontier history. City of Rocks National Park in the south has granite formations and dark skies. Yellowstone National Park touches Idaho's northeastern corner. The Lewis and Clark National Historic Trail follows water routes across the state. These units suit travelers who prefer self-directed trips and are comfortable with distances between destinations.

Nez Perce National Historical Park

Nez Perce National Historical Park is unlike almost any other NHP in the country: it is not a single bounded site but a constellation of 38 separate places scattered across four states in the inland Northwest, each tied to the history and living culture of the Nimíipuu people.

How this page is ranked

Behind the Idaho ranking

We sort by the Experience Score, a like-for-like measure of what a unit offers on paper and how reachable it is, pulled from public data and capped so one factor never runs the table. Beauty and crowds are deliberately out of it. That is the lens on all 18 Idaho entries here.

What the ranking cannot tell you: whether the views floor you, how packed a lot gets in July, trail conditions after rain, or how good a ranger walk is. A small, focused site can rank below a sprawling park and still be your better trip. Read the score for what is on offer, then open a unit for the verdict on who it actually suits.
