Getting Here and Around

Highway 20, the North Cascades Highway, splits the park's north and south sections. The gravel Cascade River Road, which runs southeast from Marblemount, peels off Highway 20; Sibley Creek/Hidden Lake Road (USFS 1540) turns off Cascade River Road to the Cascade Pass trailhead. Thornton Creek Road is another rough four-wheel-drive track. For the Ross Lake area in the north, the unpaved Hozomeen Road (Silver-Skagit Road) provides access between Hope, British Columbia; Silver Lake; and Skagit Valley provincial parks. From Stehekin, the Stehekin Valley Road continues to High Bridge, Car Wash Falls, Bridge Creek, and Cottonwood campgrounds—although seasonal floods may cause washouts. Note that a day trip isn't nearly enough to make a thorough exploration of the park: roads are narrow and closed from October to June, many sights are off the beaten path, and the scenery is so spectacular that, once you're in it, you won't want to hurry through anyway.
