Experience the full White Pass Scenic Byway on a west-to-east road trip along US Highway 12, traveling from the forested foothills near I-5 and Marys Corner to the open landscapes of the Yakima Valley near Naches. This route connects small towns, river valleys, lakes, mountain passes, wildlife areas, and outdoor recreation across one of Washington’s most scenic corridors.
Begin near Marys Corner at I-5 Exit 68 and follow US Highway 12 east toward Mossyrock. This western gateway to the byway offers access to Mayfield Lake and Riffe Lake, two popular stops for boating, fishing, paddling, camping, picnicking, and lake views.
Continue east to Morton, a historic timber community surrounded by forested foothills. Stop at the Morton Loggers’ Memorial and Morton Depot to connect with the area’s railroad, logging, and small-town heritage before continuing deeper into the Cowlitz River Valley.
From Morton, follow US Highway 12 toward Randle and Packwood. This stretch of the byway offers access to the Gifford Pinchot National Forest, the Cowlitz River, Lake Scanewa, campgrounds, trailheads, wildlife viewing, and side trips toward Mount Rainier and Mount St. Helens, along with views and regional connections to Mount Adams. Packwood is a strong stop for food, lodging, fuel, local shops, and mountain-town character.
From Packwood, continue east as US Highway 12 climbs toward White Pass. This alpine section of the byway offers mountain views, winter recreation at White Pass Ski Area, nearby hiking, camping, and access to the Pacific Crest Trail near the White Pass summit.
After crossing White Pass, descend toward Rimrock Lake and the Tieton River. This eastern section of the byway is known for lake recreation, fishing, camping, scenic viewpoints, and seasonal whitewater rafting on the Tieton River.
Continue east toward Naches, where the byway connects with the Yakima Valley and nearby Oak Creek Wildlife Area. This eastern gateway offers wildlife viewing, open landscapes, and access to additional scenic routes, including State Route 410.
Plan extra time for stops, photos, meals, short hikes, and seasonal road-condition checks. From lakes and river valleys to alpine recreation and volcanic landscapes, White Pass Scenic Byway offers one of Washington’s most complete mountain road trip experiences.
