In the southern part of the state, Craters of the Moon National Monument and Preserve showcases a different slice of rugged landscape in the form of an ancient lava flow.

Idaho State Parks present even more diversity to explore. Towering pine trees, glistening alpine lakes, and the Oregon Trail are on display throughout these public lands.
