Big Sheep Creek Back Country Byway

Tucked into the secluded southern reaches of Montana near Dell, the Big Sheep Creek Back Country Byway offers a quiet, rugged drive through part of the untamed Rockies. From Interstate 15, just north of the Montana–Idaho border, the rugged Tendoy Mountains may look impenetrable — but the Dell exit leads to a nearly hidden opening into this remote landscape (the byway is also accessible from Montana Highway 324). The route offers the opportunity to peer down into the depths of Big Sheep Creek and up into the heights of Big Sheep Canyon, passing through three distinct geological landscapes along the way: the narrow, rocky walls of Big Sheep Canyon, a broad valley framed by mountains along the Continental Divide, and — farther north — the lush, winding Medicine Lodge valley shaped by a meandering creek beneath the peak that gives it its name.

Though many years have passed, the landscape is largely unchanged from the days of early Native Americans and mountain men, offering a rare chance to experience Montana's backcountry in near-pristine condition. Stretching more than 50 miles, the route is usually passable for all types of vehicles during the summer. Plan for a relaxing three-hour drive — or take two or three days if you'd like to enjoy fishing, hiking, wildlife watching, or simply exploring the area.
