Overview

Wedged between Montana and Oregon, and often overlooked as a result, Idaho is one of Western USA's most underrated destinations. This rather large chunk of land has 114 mountain ranges and some of the most rugged mountains in the Lower 48. Over 60% of the state is public land, and with 3.9 million acres of Wilderness, it's the third-wildest state in the union.
