Camas Creek Back Country Byway

This 36-mile dirt track follows the historic route where Lewis and Clark’s expedition nearly perished from starvation in September 1805, surviving on portable soup and horse meat as they crossed the windswept Camas Prairie. The route climbs from the Centennial Valley floor through rolling sage country to Camas Meadows, where Nez Perce warriors famously scattered Army mules during the 1877 retreat. You’ll cross several creek drainages and navigate loose volcanic scree near Camas Creek Summit at 7,000 feet elevation.

This is a moderate route requiring high-clearance 4WD for rocky creek crossings and muddy sections during spring runoff. Best driven July through September when snow clears the high country. Carry extra fuel and water — services are 60 miles away in West Yellowstone or Island Park. The payoff is massive views across the Centennial Valley, quality dispersed camping near Camas Creek, and genuine solitude in country that still feels like the frontier.
