North Cascades Scenic Highway—Highway 20—the east/west girdle across the lower waist of North Cascades in Ross Lake National Recreation Area, is what keeps the region from being a roadless wilderness. Called the "most scenic mountain drive in Washington," Highway 20 was dedicated in 1972. As it is, the highway is closed through the winter because of snow, making the communities of Gorge and Diablo unreachable by overland vehicle. While some people might prefer roadlessness, you have to admit that Highway 20 makes for an awesome drive, with pristine mountain scenery almost unmarred by development.

Whatever else you do, you must stop at Diablo Lake Overlook for superb views of Diablo Lake, Sourdough Mountain, Davis Peak, Colonial Peak, Pyramid Peak, and spectacular features of the Skagit River drainage. Happy Creek Forest Walk is another good leg-stretcher, a short boardwalk through an old growth forest. And it's wheelchair accessible.

Rainy and Washington Passes in Okanogan National Forest to the east provide rest stop and picnic facilities. The Pacific Crest National Scenic Trail crosses the highway at Rainy Pass, elevation 4,860 feet. The Rainy Lake National Recreation Trail begins near Rainy Lake rest stop. This 1 mile walk to a subalpine lake accommodates wheelchairs. At Washington Pass, elevation 5,477 feet, near the rest stop and picnic area, an overlook provides breathtaking close-up views of the rugged Cascade Mountains. The Baker Lake area of Mt. Baker-Snoqualmie National Forest offers camping, boating, fishing, hiking, and picnicking.

Posted speed limits for Highway 20 are often lower than the statewide limit. Use roadside turnouts for safe scenic viewing. While your driving, watch for pedestrians and hikers on road shoulders, rocks in the roadway and wildlife.
