A 4-Day Backpacking Itinerary Through America’s Alps

Rugged, remote, and wildly underrated, North Cascades National Park is one of the most dramatic landscapes in the contiguous United States. Nicknamed “the American Alps,” this park is defined by jagged peaks, massive glaciers, turquoise lakes, alpine meadows, and some of the steepest hiking trails you’ll find anywhere in the country.

With around 300 glaciers and 300 lakes, North Cascades is the most glaciated region in the U.S. outside of Alaska, and yet, it remains one of the least visited national parks of the Lower 48. More than 90% of the park is designated wilderness, making it a dream destination for hikers, backpackers, and travelers looking to escape modern society and connect with mother nature.

I visited in mid-July for a 4-day solo backpacking trip of stunning high-mountain scenery with challenging hikes and an unforgettable overnight stay at Sahale Glacier Camp. This guide breaks down everything you need to know—from logistics and permits to a detailed day-by-day itinerary.

Know Before You Go

The North Cascades is one of the few national parks with no entry gate or entrance fee. However, to park at most trailheads you’ll need either a National Park Pass, or a National Forest Pass. These can be purchased at outdoor retailers like REI, the Newhalem Visitor Center, or the Wilderness Office in Marblemount.

Highway 20, or North Cascades Highway, is the only paved road running through the park. Many of the best hikes branch off of long, narrow dirt roads, often requiring high clearance or a 4-wheel drive vehicle. Because there is only one road, this park is often closed for snow in the winter. 

Hiking here is no joke, and requires proper preparation. The Cascades are some of the steepest mountains in America, and even a short hike here can pack serious elevation gain. Train ahead of time, bring trekking poles, and plan for heat, sun exposure, and long climbs.

Despite rumors, there are no grizzly bears currently living in this park, only black bears. Other common wildlife sightings include elk, moose, marmots, pika, mountain goats, bighorn sheep, coyote, lynx, bobcats and otters.

The park is categorized by three areas: the Lake Chelan National Recreation area in the south, the Ross Lake Area in the east, and the North Cascades Complex, which makes up the remaining mountains in the north and southwest of this park. On the west, the park is bordered by the Mt. Baker National Forest, while Canada sits at the northern border, helping to create one of the most undeveloped and protected wilderness areas in America outside Alaska.

There are some great base towns to stay at in the Cascades. Leavenworth, which is south of the park’s Lake Chelan area, is quaintly styled after Bavarian villages. On the east side lies Winthrop, a charming old west-style town with great shops, eateries and lodging such as the Sun Mountain Lodge or the Methow River Lodge, which has free continental breakfast. Also on the eastern side is Twisp, or Mazama if you prefer a smaller town closer to the park’s border.

For in-park lodging, visitors can stay at Ross Lake Resort, which hosts 14 boat-access-only cabins and requires booking well in advance. Colonial Creek Campground offers  gorgeous lakeside views of Diablo Lake, and Newhalem Creek Campground near the visitor’s center provides quick access to easy trailheads. If you can snag an overnight permit at Sahale Glacier like I did, you can camp beside a glacier at one of the highest campsites in the Cascades. 

4-Day North Cascades Itinerary

Day 1: Scenic Drive, Blue Lake and Diablo Lake Trails

Feast your eyes on the gorgeous sights of the Cascades with a scenic drive. Entering from the east, Highway 20 immediately delivers jaw-dropping scenery at Washington Pass Overlook, Ross Lake Overlook, Diablo Lake Vista Point or Gorge Lake Overlook. These turquoise lakes are stunning, and absolutely worth the stop—but fun fact: Ross, Diablo, and Gorge Lakes are man-made, created by a hydroelectric system that supplies about 20% of Seattle’s power.

After your drive, stretch your legs by hiking the Blue Lake Trail—it’s a perfect warm-up hike near Winthrop with about 1,000 feet of elevation gain. This 2.2 mile round-trip trail winds through forest before opening up to a brilliant alpine lake surrounded by peaks.

After this warmup hike, treat yourself to an incredible lakeside trail through old-growth forest and hike the Diablo Lake Trail. This 7 mile round-trip tek is especially beautiful at sunset.

After hiking, head back to Winthrop for dinner and lodging.

Day 2: Cascade Pass to Sahale Glacier

Camping at Sahale Glacier will surely be the crown jewel of your trip. There are guidelines for being in the backcountry, however. 

All backcountry camping requires a permit, and you can reserve permits on recreation.gov or pick up permits in person at the Wilderness Office in Marblemount. Bear canisters are mandatory out here, and are rentable at the Wilderness Office as well as the visitor’s center in Newhalem. Note that the Wilderness Office closes mid-day for lunch, so plan your permit pickup accordingly.

The trailhead to Sahale Glacier is located off of Cascade Pass Road, which is roughly 11 miles of poorly graded dirt. In poor weather, I imagine 4-wheel drive would be necessary here, and the road would not accommodate RVs or trailers. 

The hike into Sahale Glacier camp is about 6 miles, beginning with shaded switchbacks, climbs through alpine meadows bursting with wildflowers in yellow, purple and red, crosses snowfields, and eventually opens into a dramatic high-alpine landscape. Curious, foraging mountain goats roam the hillsides, and pikas will squeal as you inch higher and higher on the trail, alerting the other creatures of your nearing ascent. 

Camping at Sahale Glacier is surreal—tents tucked into rock walls, glaciers at your feet, and endless sunset views over jagged peaks. 

Day 3: Hike Out + Newhalem

The following day I enjoyed the company of mountain goats as I sipped coffee. Eventually, I packed up camp and hiked back, pausing for a cool dip in the alpine lake waters to ease the ache in my shoulders. 

After a quick reset in Marblemount, you’ll head to Newhalem Creek Campground, the heart of the Ross Lake Recreation Area. 

There are quite a few easy, beautiful hikes nearby to occupy your third day of exploration. Trail of the Cedars is a flat, old-growth forest loop, Ladder Creek falls has a short hike with benches and a waterfall, the Sterling Munro Trail provides a short boardwalk with views of the Picket Range, and you can swim at Diablo Lake. It may be cold, but the water will surely be refreshing! 

Newhalem is also home to the Visitor Center, a small market, and ranger programs.

Day 4: Thornton Lakes + Optional Lookouts

The Thornton Lakes Trail is a 10.4 mile round-trip hike accessible by a 5 mile long dirt road. Although this hike is strenuous, it leads to a glittering remote alpine like encompassed by steep, rocky peaks that reach toward the clouds. 

Time permitting, other options for the day include visiting Hidden Lake Lookout, which has a first-come first-served overnight stay. You can adventure to Trappers Peak for epic views, visit Sourdough Mountain, or explore Stiletto Peak, which is often less crowded. 

After hiking, continue west toward Mount Baker, Mount Shuksan, or drive back to Seattle.
