Primary access to the North Cascades and Ross Lake National Recreation Area is off of State Route (SR) 20, which connects to I-5 at Burlington. Branch routes lead to Baker Lake (Mount Baker-Snoqualmie National Forest) and the Cascade River. In winter SR 20 is closed at Washington Pass beyond Ross Lake. There is no car access to the Stehekin Valley and Lake Chelan National Recreation Area. Take Highway 2 to the town of Chelan where passenger ferry and plane access is available. There is also trail access off of SR 20. The only road access to the shore of Ross Lake is via the Silver-Skagit Road (gravel) from near Hope, British Columbia.
