How to get to North Cascades National Park
Most RV travelers approach via Interstate 5 to Burlington, then head east on State Route 20 through Sedro-Woolley and Marblemount, roughly 2.5 to 3 hours from Seattle. Spokane is about six to seven hours to the east via US-2 or SR-20, and Bellingham sits about two hours northwest. RV drivers should be ready for long mountain grades, tight curves, and hairpin turns over Rainy Pass (4,855 ft) and Washington Pass (5,477 ft), and the North Cascades Highway closes seasonally between those passes due to snow and avalanche danger. Seattle-Tacoma International Airport (SEA) is the nearest major airport for fly-and-rent trips.
