Planning Your Scenic Drive to North Cascades
A trip along the North Cascades Highway offers breathtaking views, diverse landscapes, and unforgettable experiences. Proper planning ensures you’ll make the most of this stunning journey through one of America’s most beautiful mountain ranges.
Choosing the Right Time to Visit
The North Cascades Highway (State Route 20) is typically open from mid-May through mid-November, with winter closures due to heavy snowfall and avalanche risk. Summer (July-August) brings warm weather and full access to trails and viewpoints, but also more visitors.
Fall is magical when the mountains burst with color as golden larches transform the landscape alongside red maples and yellow willows. This spectacle usually peaks from late September to mid-October.
Spring offers flowing waterfalls and blooming wildflowers, with fewer crowds. Weather can be unpredictable, so always check road conditions before heading out. There’s no entrance fee for driving through the national park, making this a budget-friendly adventure.
Essential Stops Along the Way
