The Cascade Lakes Scenic Byway continues south along the west side of Mount Bachelor. Beyond Mount Bachelor Ski Area, the byway passes Todd Lake, Sparks Lake, Devils Lake, Elk Lake, Hosmer Lake, Lava Lake, Little Lava Lake, and Cultus Lake. South of Crane Prairie Reservoir, the two routes split, with the scenic byway continuing to head south towards its terminus at Oregon Route 58. Century Drive instead heads back to the east, north of the Wickiup Reservoir, and then heads northeast parallel to the western shore of the Deschutes River. It eventually crosses the river, runs north for several miles, and then terminates at an intersection with US 97 near the resort community of Sunriver.
