How To Get to North Cascades National Park

North Cascades National Park is three hours from Seattle in northern Washington state, making Seattle-Tacoma International Airport (SEA) the closest starting point to the park. You’ll gain primary access to the North Cascades Highway (SR 20) from there. Your drive will be roughly 120 miles from the airport to the national park entrance.

If you’re driving from the west, take Interstate 5 to exit 230 to join the North Cascades Highway. Alternative routes include driving the Silver-Skagit Road and SR 542 for access to Copper Ridge and Hozomeen. 

Best Time To Go to North Cascades National Park

The best time of year to visit North Cascades National Park is, without a doubt, from June to September. North Cascade National Park’s weather from summer to fall is the safest and most pleasant during these months.

The snow has melted at this time, and both low and high-elevation trails are open for hiking. You can also partake in many outdoor activities, such as camping, birdwatching, fishing, watersports, wildlife watching, and backpacking.

The peak season means that trails and campsites will be much busier, so be prepared. However, more and more people are visiting until November as the fall scenery, and fewer crowds are a big draw for some.

Worst Time To Go to North Cascades National Park

The worst months to visit are between December and March, mainly because the cold weather can pose dangers to the park visitors. The North Cascades Highway is usually closed during this time of year for safety purposes, which makes the park inaccessible for the most part. 

The highway can remain closed until May, even if the park is technically open year-round. Additionally, you’ll find that trails and dirt roads may be covered with snow deep into summer, long after the highway is open.

Visiting North Cascades in Spring

Spring at North Cascades gradually warms after a crisp winter. As the snow melts, it welcomes budding vegetation and wildlife activity. Gorgeous wildflowers can be seen blooming at lower elevations. 

Trails at higher elevations still deal with lingering snow, sometimes into the summer months, so your choice of hikes may be limited from March to May. During spring, temperatures typically range from 40°F to 60°F (4°C to 16°C). 

Visiting the national park from late spring onwards is best, as Highway 20 is not typically open until April or May. Access to certain areas in the park, plus services and facilities, may also be limited during spring.

Things To Do in North Cascades in Spring

There’s still quite a bit you can do at North Cascades if you visit in spring, whether it be hiking, sightseeing, or wildlife viewing.

You’ll find that temperatures generally range from 60°F to 80°F (16°C to 27°C) during summer. And the weather is reliably good during the months of June to August.

Be prepared for popular trails to be crowded as the summer months bring in the most visitors.

Things To Do in North Cascades in Summer

You’ll have access to most, if not all, of the outdoor activities available at North Cascades National Park during the summer peak season.

Drive North Cascades Highway

The North Cascades Scenic Highway is a 30-mile drive across the North Cascades National Park and the main entry point for visitors. It’s also perfect for scenic drives that lead you through old-growth forests, mountain scenery, and glorious waterfalls. 

The drive takes an hour, but you’ll likely spend more time stopping at iconic sights and exploring the surroundings. See Gorge Creek Falls, Diablo Lake Overlook, Happy Creek Forest Walk, and many more fascinating sights when you drive through the park.

Visit the Quiet Community of Stehekin

Located on Lake Chelan, the Stehekin community is hidden within the North Cascade National Park and can only be accessed by foot, boat, or plane. There is plenty to do there, from camping, hiking, lodging, and cultural and historical activities. 

Be sure to visit sights like Rainbow Falls and North Cascades Lodge when there.

Visiting North Cascades in the Fall

North Cascades is one of the best national parks to visit in the fall. Fall is becoming more popular to visit since September to November are generally less crowded.

The shoulder season boasts a stunning explosion of colors — reds, oranges, and golds from cottonwoods, aspens, and maples decorate the glacial park during this season. You can still enjoy high-elevation hikes, backpacking, and increased elk sightings.

Prepare for the slightly chilly weather ranging from 40°F to 60°F (4°C to 16°C) and the possibility of early snowfall. Certain services scale down at this time, and you may be unable to access areas where snow can cause potential dangers.

Visiting North Cascades in Winter

North Cascades’ winter is undoubtedly an alpine wonderland. You’ll see the snow-capped peaks of the Cascade Mountains, the presence of fluffy, white mountain goats, and the stunning glaciers. 

Many outdoor enthusiasts enjoy skiing, snowshoeing, and snowmobiling during this period. However, this weather is not the most suitable for camping as average temperatures can range from 20°F to 40°F (-7°C to 4°C).

Given the avalanche risk due to heavy snow and steep terrain, the main road through the park, Route 20, remains closed in the winter. However, you can enter by skiing, snowshoeing, or going backcountry camping, but experienced travelers generally favor this approach.

Things to Do in North Cascades in Winter

While many high-elevation trails are snow-covered and restricted during winter, that doesn’t mean there aren’t things to do while visiting the national park in winter. 

Diablo Lake Vista Point

While visiting the turquoise waters of Diablo Lake is a year-round delight, Diablo Lake in winter is a stunning sight with its snow-dusted banks and crystalline waters. The best vantage point to absorb the awe-inspiring sights of the lake is at Diablo Lake Vista Point.
