April 23, 2025 – Good news for outdoor enthusiasts and scenic drivers! The Washington State Department of Transportation (WSDOT) today announced the official reopening of State Route 20, the North Cascades Highway, for the 2025 season. The popular scenic byway, which traverses the heart of the North Cascades National Park, is now fully accessible to the public after its annual winter closure due to heavy snowfall and avalanche risk.
The reopening marks the return of access to some of Washington’s most breathtaking landscapes. Highway 20 offers unparalleled views of jagged peaks, pristine alpine lakes, and lush evergreen forests. Its reopening is eagerly anticipated each spring by hikers, backpackers, photographers, and anyone seeking a stunning drive through the Cascade Mountains.
This year’s reopening comes after diligent work by WSDOT crews who have spent weeks clearing snow, removing debris, and ensuring the roadway is safe for travel. The depth of the snowpack this past winter presented significant challenges, making the reopening a testament to their hard work and dedication.
What This Means for Visitors:
The reopening of Highway 20 unlocks access to a plethora of recreational opportunities within the North Cascades National Park and surrounding areas, including:
- Hiking and Backpacking: Numerous trailheads along Highway 20 provide access to iconic trails such as the Pacific Crest Trail, Cascade Pass and Sahale Arm, Diablo Lake Trail, and many more ranging in difficulty and length. Backpackers with permits can now embark on multi-day adventures into the wilderness.
- Scenic Driving: The highway itself is a destination. Travelers can enjoy pull-offs with panoramic vistas, perfect for photography and soaking in the natural beauty. Popular viewpoints include Diablo Lake Overlook and Washington Pass Overlook.
- Camping: Several campgrounds along Highway 20 and in the surrounding national forest are now open or will be opening soon, offering opportunities for overnight stays amidst the stunning scenery. Reservations are often recommended, especially during peak season.
- Wildlife Viewing: The North Cascades are home to a diverse array of wildlife, including black bears, deer, marmots, and various bird species. While driving or hiking, visitors may have the chance to spot these creatures in their natural habitat. Remember to maintain a safe distance and never feed wildlife.
- Visitor Centers: The North Cascades National Park Visitor Center in Newhalem and the Wilderness Information Center in Marblemount are now fully operational, providing valuable information, maps, and permits for backcountry travel.
Important Considerations for Travelers:
While the highway is now open, visitors should be aware of the following:
- Early Season Conditions: Higher elevation trails may still have snow and ice. Hikers should be prepared with appropriate gear, including traction devices, and check trail conditions before heading out.
- Construction and Maintenance: WSDOT may still be conducting minor maintenance work along the highway. Be prepared for potential delays and follow all posted signage.
- Weather: Mountain weather can change rapidly. Check the forecast before your trip and be prepared for varying conditions.
- Reservations and Permits: Backcountry camping and some popular day hikes may require permits or reservations. Check the North Cascades National Park website for specific requirements.
- Leave No Trace: Remember to practice Leave No Trace principles to protect the delicate environment of the North Cascades. Pack out everything you pack in, stay on trails, and minimize your impact.
The reopening of Highway 20 marks the beginning of another exciting season in the North Cascades. Whether you’re planning a challenging hike, a scenic drive, or a peaceful camping trip, the reopening of this iconic highway provides the gateway to unforgettable experiences in one of Washington’s most treasured landscapes.
