Introduction
The North Cascades in Washington State are one of the wildest, wettest, and most spectacular mountain ranges in the continental United States. With over 300 glaciers, countless turquoise lakes, and some of the densest trail wildflower displays anywhere in the country, the North Cascades reward the hikers willing to earn their views.
The Classic: Maple Pass Loop
The Maple Pass Loop (7 miles, 2,000 feet gain) near Rainy Pass on Highway 20 is the most famous day hike in the North Cascades — and for good reason. The trail climbs through old-growth forest to a high ridge with 360-degree views of Lake Ann and Maple Pass, then descends through a meadow blazing with wildflowers in August. Do it clockwise for the best views on the descent. No permit required for day use.
Backpacking Route: Copper Ridge Loop
For a 4–6 day backpacking adventure, the Copper Ridge Loop (34 miles) in North Cascades National Park is one of the premier routes in Washington. The route climbs to an unmanned fire lookout at Copper Lookout (elevation 6,260 feet) with panoramic views of the Cascades, passes through Egg Lake basin, and traverses high ridgelines before descending back via Chilliwack River valley.
Key campsites include Egg Lake, Copper Lake, and Silesia Creek. Water is plentiful but must be filtered. Bears are common — hang food or use a bear canister (required).
Permits
North Cascades National Park backcountry permits are required for overnight camping in the park. They can be obtained at the Wilderness Information Center in Marblemount. A small number of permits are available through recreation.gov; the majority are walk-up permits available the day before or day of your trip. Summer weekends can have competition for popular zones.
Wildflower Season
The wildflower peak in the North Cascades varies by elevation. Valley floors: late June–July. High meadows (like Maple Pass): typically late July–mid August. Higher passes: August. The exact timing shifts year to year based on snowpack — follow the WTA (Washington Trails Association) trip reports for current conditions.
Gear Considerations
The North Cascades receive enormous precipitation — even in summer, afternoon rain is common. Waterproof layers, gaiters, and a tent with good rain fly performance are essential. Trails can be muddy and overgrown. Bring trekking poles for steep descents on wet terrain.
Getting There
Highway 20 (North Cascades Scenic Highway) is the main corridor through the park, connecting Sedro-Woolley to Winthrop. The highway closes in winter — it typically reopens in April. Rainy Pass trailhead for Maple Pass is 135 miles from Seattle (about 2.5 hours).
