City of Rocks is a scenic journey around the Albion Mountains, through the granite spires and sculptured rock formations of the City of Rocks National Reserve. The byway also travels across southern Idaho’s sage-covered valleys and wide open spaces. You’ll also pass through patches of Lombardy poplars, first brought to this region by the pioneers. The trees almost seem out of place for this part of Idaho.
City of Rocks National Reserve is administered cooperatively by the National Park Service and Idaho Department of Parks and Recreation. This area is rich in history. Shoshone and Bannock Indians once traveled, hunted, and gathered pinyon nuts here. Emigrants following the California Trail or Salt Lake Alternate Trail passed through this area, often signing their names on the rocks with axle grease. Recreational opportunities for camping and rock climbing are among the attractions available.
