Backpacking in North Cascades
👌 Worth visitingnational park ranked #21
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

Diablo Lake glows an opaque turquoise from glacial rock flour, and you can see it from the pullout on Highway 20 (North Cascades Highway) in the north of the United States, roughly east of Seattle. I expected a quiet wilderness and found a road lined with cars at every overlook, then silence ten minutes up any trail. Cell service vanishes, the highway closes in winter, and permits vanish faster than weekend plans. Book ahead. Best for hikers who like steep climbs and solitude; skip it if you want drive-up easy.

✨ Why go?
Ranked #21 national park in the USAWhy North Cascades should be on your travel list

North Cascades National Park rewards backpackers who plan their own route, because the real prize is the backcountry, with 300-plus glaciers and camps that need a permit rather than a tour guide. Trails such as Cascade Pass and the Thunder Creek valley let you string together multi-day loops at your own pace. Roadside campgrounds along Highway 20 keep the budget low, and the park suits self-guided travelers completely, since no operator can offer anything the trails don't.

💡 HighlightsEssential experiences to have while exploring North Cascades

  1. Diablo Lake Overlook: The milky turquoise lake, colored by glacial silt, ringed by jagged peaks. It is the park's signature view, right off the highway.
  2. Cascade Pass: A steady switchback climb to a saddle with glaciers, hanging valleys and marmots whistling from the boulders.
  3. Thunder Creek Trail: Old-growth cedar and Douglas fir along a glacier-fed creek, gentle enough for families and the gateway to longer trips.
  4. Ladder Creek Falls and Gardens: A short walk at Newhalem with colored lights on the waterfall, a quirky relic of the hydro town.
  5. Sahale Arm: A high ridge beyond the pass with close views of Sahale Glacier and, for campers, a hard-won night above the clouds.
  6. Ross Lake: A long, deep reservoir with remote boat-access camps, ideal for paddlers and quiet shoreline hiking.
  7. Washington Pass Overlook:

North Cascades National Park charges no entrance fee, so the overlooks, Thunder Creek and the Ladder Creek Falls trail cost nothing.

🛏️ Where to stay?Best areas to stay in the USA

North Cascades National Park has no road-accessible lodging, so most backpackers camp. Inside the park, Colonial Creek and Newhalem Creek campgrounds off Highway 20 cost about US$20 to 24 a night, and permitted backcountry sites cover the rest. Stehekin, reached by ferry, floatplane, or a long hike, has the North Cascades Lodge and several walk-in sites. Outside, Marblemount is the closest town with motels and a ranger station for permits. Concrete and Sedro-Woolley suit cheaper bases on the west side, and Winthrop has hostel-style rooms and more variety on the dry east side.

  • Thunder Creek Trail: Easy to moderate, mostly flat, 2 to 4 hours for the first miles through old-growth forest, with longer backcountry options.
  • Maple Pass Loop: About 7 miles, 4 to 5 hours, moderate, with ridge views and larch color in autumn.
  • Wildlife: Black bears, marmots, pikas and mountain goats are all seen; store food properly.
No public transit serves the park, so you need a car, and Highway 20 closes through winter. Weekends in July and August bring crowds at Cascade Pass, where the parking lot fills early. Overnight backcountry stays need a permit, but there is no entrance fee.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetyStaying Safe: What Travelers Should Know

Most trouble here comes from weather and steep terrain, not animals. Storms roll in fast, snow lingers on high passes into July, and trails climb hard, so carry layers, traction in early season, and a paper map since signal is rare. Black bears live here and grizzlies are extremely rare, so hang or canister your food and make noise in dense brush. Wildfire smoke can cloud late summer days, so check conditions with the ranger station before heading out.

FAQTraveler FAQ

Plan three to five days for North Cascades National Park if you want a day on Highway 20 viewpoints and a night or two on trail. Day hikes like Maple Pass (about 11 km, 6 hours) fit in a day, while Cascade Pass and Sahale Arm suit an overnight. Reaching Stehekin adds at least two days.
North Cascades National Park is hard without a car, since no public transit runs along Highway 20. Most visitors drive from Seattle, about 2.5 to 3 hours to Newhalem. Stehekin is car-free once you arrive, reached by the Lady of the Lake ferry from Chelan (about 4 hours one way) or by floatplane.
North Cascades National Park charges no entrance fee, and day hikes need no permit. Overnight stays in the backcountry require a permit, US$10 per adult (free for 15 and under) plus a US$6 reservation fee through recreation.gov, with some walk-up permits at ranger stations. Parking at the Northwest Forest Pass trailheads outside the park may need a pass of about US$5 per day.
⚠️ Things can change over time, so always validate details locally before you go.

We 💚 feedbackParting advice and final tips

North Cascades National Park pairs well with the Methow Valley on the dry east side, or with a Puget Sound loop via Highway 20. I would build the route west to east, hike early, and keep a permit-backed night in reserve.

✈️ When did I visit the USA?
In January 2023 I visited New York. Many years before, before digital cameras existed, I discovered most of the national parks in the West.
