The Cascades Lakes Scenic Byway (Forest Route 46) is a National Scenic Byway in central Oregon in the United States. It runs for 66 miles (106 km) in the rugged country of Deschutes and Klamath counties on the east side of the Cascade Range. It offers particularly good views of Mount Bachelor, Broken Top, and the Three Sisters (Oregon) mountains and provides access to many recreational facilities in central Oregon. The route is so named because it weaves past a number of small natural lakes along the Cascades as well as several reservoirs on the upper Deschutes River.
