One little-known fact: the drive includes a 12-mile stretch on US-12 that follows the historic Nez Perce Trail through the Clearwater National Forest, a segment designated as a National Scenic Byway. This road trip offers a diverse blend of high plains, mountain passes, and rainforest-like valleys. how to find the best stops and hidden gems between cities is a helpful resource for planning detours.

The US-12 section through the Nez Perce-Clearwater National Forest is winding and narrow; use caution. In Washington, US-101 along Hood Canal is scenic but can be congested.
