The West Cascades Scenic Byway is a 220-mile (350 km) National Scenic Byway in the U.S. state of Oregon.

[1] The route is designed to provide a tour on the west side of the Cascade Range along the east side of the Willamette Valley.

Much of the route is very sparsely populated, passing through timber regions in the Cascades.

From Estacada the route follows the valley of the Clackamas River upstream on Oregon Route 224 into the Mount Hood National Forest, then south along the Breitenbush River to Detroit on the North Santiam.

The route provides views of old growth fir trees and jagged volcanic peaks.
