The best way to enjoy scenic Sacajawea Historic Byway drive is by starting at the fascinating Sacajawea Interpretive, Cultural and Education Center in the city of Salmon, Idaho. You can learn about Sacajawea, an “Agai Dika” Lemhi Shoshone woman, who was an interpreter for Lewis and Clark, and helped the expedition find the Salmon River.

The byway starts in Salmon, on Idaho 28 going southwest for 120 miles to exit 143. It then follows Idaho 33 for 12 miles until the intersection of Interstate 15 and Idaho 33. The whole byway is about 132 miles long and will take you about two and half hours, without stops. Along the way you will find fossils of the Pleistocene lion, extinct for thousands of years, fantastic Native American rock art, and legacies of the Lemhi-Shoshone people. You will pass through Gilmore, a ghost town of an abandoned mining settlement and you will enjoy spectacular scenery wherever you look. Sacajawea Historic Byway Map
