The Cascades Lakes Scenic Byway (Forest Route 46) is a National Scenic Byway in central Oregon in the United States. It runs for 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 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.
