Hamilton, MT to Pinedale: Essential Road Trip Guide

The drive from Hamilton, Montana, to Pinedale, Wyoming, traverses the dramatic Bitterroot Valley, crosses the Continental Divide twice, and skirts the massive Yellowstone Caldera. This 300-mile journey passes through several distinct ecosystems, from pine forests to sagebrush steppe, with the towering Wind River Range as a finale.

One historical quirk: the route roughly follows the Nez Perce Trail, the path taken by Chief Joseph and his band during their 1877 flight from the U.S. Army. Modern travelers can occasionally spot remnants of old wagon ruts near Salmon, Idaho.

• Road quality: From Hamilton to Salmon, US-93 is a two-lane highway with passing lanes; from Idaho Falls to Pinedale, US-26 is well-paved but can have winter ice.
