The Lewis and Clark Backcountry Byway and Adventure Road is a 36-mile loop drive through a beautiful and historic landscape following the Lewis and Clark National Historic Trail and the Continental Divide National Scenic Trail. Visitors will be treated to incredible views of the Lemhi Valley and the surrounding mountain ranges; truly some of the finest scenery in America! The mountains, evergreen forests, high desert canyons and grassy foothills look much the same today as when the Lewis and Clark Expedition passed through in 1805. Take a slow and meandering journey along this drive and take time to stop along the way for plenty of hiking, fishing, mountain biking and exploration. With a 4,000 foot gain and loss in elevation, expect some steep grades too. Lemhi Pass is well-known for its wildflower displays in the spring and summer. Captain Lewis collected three new plant species in this area: mountain maple, common snowberry and Lewis's monkey flower. You might see elk, mule and whitetail deer, black bear, moose, pronghorn antelope, coyotes and many smaller mammal species. Early mornings and evenings are the times to look for wildlife, particularly where the forest and meadow meet. By late September shorter days and cooler temperatures release hues of red, yellow, and gold in aspens, cottonwoods, willows and shrubs. Don t miss Agency Creek in October it's beautiful!
