Salmon to Athol: Idaho's Scenic Road Trip Guide

This route traces the dramatic transition from Idaho's rugged Salmon River country to the lush, lake-filled panhandle. You'll climb over the Bitterroot Mountains, pass through the vast Frank Church-River of No Return Wilderness, and end near the shores of Lake Pend Oreille, one of the deepest lakes in the U.S.

The journey crosses the Continental Divide at Lost Trail Pass (elev. 7,014 ft) and follows the historic Nez Perce Trail. The Salmon River, often called the 'River of No Return,' has carved a canyon deeper than the Grand Canyon in places, offering breathtaking views.
