North Cascades National Park is open every day of the year. Winter weather however, tends to dictate when most visitor facilities and roads are open. Generally from late May to late October, facilities are open to welcome the increase in summer visitors.
Nearest major airport is Seatac near Seattle, Washington. Chelan Airways (509/682-5555)provides floatplane access to Stehekin in Lake Chelan National Recreation Area.
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.

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.
