Everything you should know about North Cascades National Park

A majestic landscape of towering peaks, evergreen forests, glacier-fed rivers, and pristine lakes, North Cascades National Park in northwestern Washington state preserves some of the wildest and most spectacular places in the United States. Far more than just a national park, it’s part of a 684,000-acre contiguous complex that also includes two national recreation areas (Lake Chelan and Ross Lake) and is managed entirely by the U.S. National Park Service. More than 94 percent is federally designated wilderness. 

Surrounded by tens of thousands of acres of national forest, the complex also encompasses more than 300 glaciers and dozens of rivers and lakes. Nearly 400 miles (643 km) of trails wind through dense forests and into the high alpine country. Wildlife abounds, from readily seen black bears, deer, and bald eagles to pikas, marmots, and wolverines at higher elevations. 

Despite its manifold charms, the North Cascades is one of the least visited national parks in the United States, with minimal infrastructure. State Route 20, also known as the North Cascades Highway, bisects the complex through the Cascade Pass, following the Skagit River and other waterways. Though within easy reach of two of the region’s largest urban areas, Seattle and Vancouver (Canada), North Cascades National Park is truly a world apart, with gorgeous views aplenty to delight casual visitors, but it requires time and effort to get to know in depth. 

Best times to visit North Cascades National Park

Every season has its beauty in the North Cascades, but not every part of the park is open year-round. Heavy snow typically closes much of the North Cascades Scenic Highway (State Route 20) across the mountains from November or December to April or May. Consult the park’s website for current road conditions before visiting. 

Areas at lower elevations become accessible as spring advances, but summer and early fall are the best times to visit for snow-free trails and access to the high country. As temperatures warm and snow melts, wildflowers appear, blanketing the alpine meadows in a brilliant carpet of blooms. At lower elevations, flowers typically begin to blossom in early spring, spreading up the mountain slopes as the season advances.

Where to find the best views in the park 

The North Cascades Highway is arguably one of the most beautiful drives in the United States, climbing from near sea level in the west to 5,477 feet (1,669 meters). It follows the Skagit River and a string of alpine lakes and creeks before descending to the arid landscapes east of the Cascade Mountains. Along the way, stunning vistas unfold at every bend in the road, revealing jagged peaks, dense forests, tumbling rivers, and turquoise lakes. The Diablo Lake and Ross Lake overlooks provide panoramic views, while other stops along the highway offer easy access to scenic spots such as Gorge Creek Falls, Ruby Creek, and Rainy Lake.

Beyond the roadside viewpoints, there are endless opportunities for hikes deeper into the park’s dramatic scenery. Hikers can’t go wrong in a place as stunning as the North Cascades. The only limits are the weather, time, and your own stamina.

Where to find the best hiking trails

A network of trails crisscrosses the park complex, ranging from short, easy forest and riverside walks to challenging multiday treks involving significant elevation gain and loss. Trails at lower elevations are usually clear from April to mid-October, while high-elevation routes often have snow into the summer. Confirm trail status before setting out, especially early or late in the season.

Near the visitor center in Newhalem, the River Loop Trail is an easy two-mile route through the forest and along the Skagit River, with minimal elevation change. A more challenging day hike with ample reward for effort is the Thunder Creek Trail, a roughly 10-mile (16-kilometer) round trip that follows a creek to a mountain pass with glacier views. The Cascade Pass Trail is another popular option with ascending switchbacks through the forest that reveal expansive views of the valley, mountains, and glaciers. Hikers can continue to Sahale Arm for more spectacular views, with a total round-trip distance of about 12 miles (19.3 km).

The best spots to see wildlife

Visitors to the North Cascades should always be on the lookout for wildlife. Mountain goats and pikas are often seen high on talus slopes throughout the park, including along the Cascade Pass Trail. Hoary marmots typically frequent alpine meadows, such as those around Sahale Arm. Wolverines roam widely throughout alpine tundra and subalpine forest, though you have to be very lucky to spot one because the population is very small and tends to keep to very remote areas. With luck, you may spot a white-tailed ptarmigan at around 7,000 feet (2,133 meters). A wide variety of smaller birds, including hummingbirds, flycatchers, and warblers, also return to the slopes of the North Cascades in warmer months. Birders will find these fowls throughout the park—in habitats ranging from wetlands and mountain meadows to forests at lower elevations.

Salmon migrate up the Skagit River every autumn to spawn, drawing large numbers of bald eagles that feed on their carcasses and perch in trees along the riverbanks from around late December through early February. Many other raptor species migrate through the area in spring and fall, while black bears and deer are seen in the park’s lower elevations year-round, including along the Skagit River. Cascade Pass and Sahale Arm are also good places to keep an eye out for bears and other wildlife. 

Expert recommendations and tips

With minimal road access, visitors who are not prepared to venture into the wilderness are mostly limited to locations within relatively easy reach of the highway—and there’s nothing wrong with that. “Walk out to the Sterling Monroe boardwalk, get a view of the Picket Mountain Range. You can see a glacier right from there, and one of the very rugged, jagged mountains out in the distance that really exemplifies the North Cascades,” says Yeva Cifor, a park ranger for North Cascades National Park. “Then, as you continue further east, stop by the Skagit River, do a short walk, see some of the wildlife, and stop at some of the main overlook points like Gorge Creek Falls or Diablo Lake Overlook. Especially in the middle of the summer, you'll get to see that quintessential turquoise water, and then also the overlooks for Ross Lake.” 

Cifor also recommends hiking on some of the trails through sub-alpine zones, with vast views and wildlife readily seen. One of her most memorable experiences occurred soon after she began working at the park. “I hiked up to Cascade Pass and was able to touch the glacier. Even though it was a pretty busy, warm summer day, I got to just sit up there and eat my lunch and watch the mountains,” she recalls. Another favorite is Thunder Knob, a 3.6-mile round trip with gorgeous views of Diablo Lake.

Things to do in North Cascades National Park

Since the North Cascades is a wilderness park, hiking, backpacking, and backcountry camping are the main activities, and visitors should be well prepared for remote conditions. 

One very popular backpacking route is the 34-mile Copper Ridge Loop, for which permits are released in early March through a two-week lottery process on rec.gov. Any unclaimed permits are released through a secondary lottery, with a percentage held for last-minute walk-ins.

Within the Ross Lake and Lake Chelan National Recreation Areas, there are opportunities for kayaking, paddleboarding, canoeing, and motorboating, as well as easier hikes and scenic drives. Another popular activity is rafting on the Skagit River, starting from near Newhalem and Marblemount.

Best things to do for families

Many of the park’s shorter trails, including those to scenic roadside viewpoints, are family-friendly and have minimal elevation gain. Near the visitor center in Newhalem, the Trail of the Cedars and Ladder Creek Falls are two short trails suitable for all ages. Nearby, the easy River Loop Trail winds through the forest and along the Skagit River for approximately two miles. 

Children can earn a free junior ranger badge by picking up a booklet at the visitor center and completing a variety of activities designed to help them learn about the nature and history of the North Cascades. The visitor center has other resources and periodic family programs, as well as short trails nearby. 

Where to stay

North Cascades is a wilderness park, with camping the only option for overnight stays. The park has four campgrounds along the North Cascades Highway, as well as others in the Lake Chelan National Recreation Area. Campsite reservations are required from late May through early September, with most available up to six months in advance. A small number of sites are held for last-minute bookings. 

Boating campsites along Ross Lake and Diablo Lake can also be reserved through the same permit system. Permits are also required for overnight stays in the backcountry and can be reserved during high season through the Wilderness Information Center in Marblemount, for groups of up to 12 people.

Those seeking more creature comforts should look outside the park proper for lodges and motels in communities to the east and west, as well as around Lake Chelan to the south. The greatest concentration of lodging is available east of the park around Winthrop and Twisp, which offer a wide range of accommodations. West of the national park, the stretch of State Route 20 from Concrete to Marblemount also has several options. 

What else you should know

Visitors venturing into the backcountry should follow strict “Leave No Trace” guidelines and be equipped with the 10 Essentials in case of unexpected situations. Stay alert for bears at all times and carry bear spray. Check the park’s website, stop by a visitor center, or e-mail noca_information@nps.gov for information about current conditions before setting out. Road access is very limited between November and March due to heavy snow, so even if you are just planning to drive the North Cascades Highway, check the park’s website for updates to avoid disappointment.

A shared information center for the national park and the Mount Baker-Snoqualmie National Forest is open year-round in Sedro-Woolley, at the western end of the North Cascades Highway, with seasonal hours listed on the national park’s website. The main visitor center in Newhalem is open in high season, typically from late May until late September. Park staff monitor and respond to e-mails year-round.

How accessible is the park?

As a wilderness park, North Cascades encompasses many remote locations with often challenging terrain. However, park visitors and information centers are fully accessible. There’s a flat boardwalk and several low-grade, smooth-surfaced trails near the visitor center, as well as the 1/3-mile Happy Creek Forest Walk near milepost 135. 

Accessible picnic areas are available at Goodell Creek and Newhalem Creek Campgrounds; most campgrounds also have accessible restrooms and campsites.
