Cascade Pass Trail

The Cascade Pass Trail is a 5.9 km (3.7 mi) one-way hiking trail in North Cascades National Park, Washington, United States, gaining 518 m (1,700 ft) of elevation to an alpine pass at 1,678 m. Rated moderate to the pass and strenuous on the optional Sahale Arm extension, it delivers sweeping glacier views and wildflower meadows that rank it among the finest hikes in the Pacific Northwest.

About the Cascade Pass Trail

Cascade Pass has drawn mountain travellers for thousands of years. Indigenous peoples — including the Sauk-Suiattle and Upper Skagit tribes — used the pass as a trading route connecting communities on either side of the range long before European exploration. Today the trail is managed by North Cascades National Park, one of the most rugged and least-visited parks in the contiguous United States, covering 271,000 hectares of near-roadless wilderness in the northern Washington Cascades.

The trail begins at the Cascade River Trailhead, reached via 23.1 miles (37 km) of Cascade River Road from Marblemount, Washington — paved for the first third, gravel for the rest. The full point-to-point route extends 23 miles (37 km) to the remote village of Stehekin on the southern shore of Lake Chelan: a multi-day wilderness traverse crossing no roads and ending at a settlement accessible only by ferry or floatplane.

For most visitors the trail is a vigorous day hike — 3.7 miles (5.9 km) each way with 1,700 ft (518 m) of climbing — but the payoff is extraordinary. A broad alpine meadow opens at the pass, framed by hanging glaciers on Johannesburg Mountain, the serrated ridgeline of Magic Mountain, and ice-capped Sahale Peak directly overhead. Strong hikers extend the trip on the Sahale Arm, a 2.2-mile (3.5 km) spur gaining a further 2,240 ft (683 m) to reach the toe of Sahale Glacier at 2,240 m (7,250 ft).

The trail's "hiker only" designation means no mountain bikes, horses, or motorised vehicles are permitted. Pets are also prohibited throughout the park's backcountry, preserving the fragile alpine vegetation that recovers extremely slowly after disturbance. No campfires are allowed anywhere on the route.

Route Overview & Stages

The complete Cascade Pass Trail is a point-to-point route of approximately 37 km (23 miles). Most day hikers tackle only the first two stages to the pass and return the same way. The table below covers the full traverse to Stehekin for those planning a multi-day trip.

Stages 4 and 5 distances are approximate. Check the Washington Trails Association for current road opening status and shuttle schedules before your trip.

Highlights & Points of Interest

• Cascade Pass (1,678 m / 5,392 ft): The centrepiece of the hike — a broad alpine saddle with sweeping views of glacier-draped peaks in every direction. Even the upper meadow approach, threaded through heather and talus, rewards hikers before the pass itself comes into view.
• Sahale Arm & Sahale Glacier Camp: The 3.5 km spur north from the pass climbs subalpine meadows and talus to a spectacular high camp at 2,240 m (7,250 ft), perched on rock beside the retreating Sahale Glacier. Widely regarded as one of the finest backcountry campsites in the entire Cascade Range.
• Johannesburg Mountain (2,799 m / 9,186 ft): The heavily glaciated dark wall to the south dominates the view from the pass. Its hanging glaciers regularly calve ice; the low rumble of avalanches is common on warm afternoons throughout July and August.
• Magic Mountain (2,414 m / 7,919 ft): The serrated ridgeline to the north is a sought-after technical climber's objective, forming a dramatic backdrop throughout the upper trail that grows more impressive the higher you climb.
• Heather & Huckleberry Meadows: Dense heather and huckleberry blanket the upper kilometre to the pass, peak-blooming in late July alongside Indian paintbrush and lupine. Come September the same slopes ignite in vivid crimson and gold.
• Pelton Basin: A quiet hanging basin just east of the pass with a designated backcountry campsite, seasonal meltwater streams, and close-up glacier views. A good first-night stop for those doing the traverse.
• Basin Creek Camp: A forested riverside camp approximately 13 km (8 mi) from the trailhead — a natural second night for multi-day hikers descending toward the Stehekin valley.
• Stehekin & Lake Chelan: The dramatic finish of the full traverse — a car-free village at the head of 90 km Lake Chelan, accessible only by boat or floatplane. The Lady of the Lake ferry provides a scenic three-hour return to the town of Chelan.

Best Time to Hike the Cascade Pass Trail

The Cascade River Road typically opens in late June, occasionally delayed to early July in heavy snow years. The hiking season runs from late June through mid-October, with the peak backcountry window from mid-July through September. As of 2026, road opening dates and current trail conditions are updated weekly on the North Cascades National Park website — always check before making the drive from Marblemount.

July brings wildflowers at their peak — Indian paintbrush, heather, and lupine transform the upper meadows into a vivid tapestry. Snowfields may linger on the Sahale Arm spur through mid-month, and an ice axe is recommended for the Sahale Arm before late July. Expect some afternoon cloud build-up and occasional thunderstorms.

August is the single best month to hike Cascade Pass. Temperatures at the pass average 12–18 °C (54–64 °F) during the day, precipitation is at its annual minimum, and all snow on the main trail has typically cleared. Huckleberries begin to ripen on the upper slopes, and trail conditions are at their most stable and predictable. Weekends draw crowds at the trailhead; start early or aim for a weekday if possible.

September rewards hikers with spectacular fall colour as the huckleberry slopes turn crimson and gold, and crowds thin noticeably. Overnight temperatures drop sharply, approaching 0 °C at the pass, and the Sahale Arm can receive early-season snowfall from late September onward. Day hiking remains excellent through mid-month.

October through May the road closes for the season and the trail carries significant snowpack. Winter access requires mountaineering experience, avalanche awareness, and full winter gear.

Practical Information

Accommodation

There is no camping at Cascade Pass itself. Four designated backcountry sites serve the full route:

• Pelton Basin Camp (3 sites, ~6 km / 3.7 mi from trailhead): The closest overnight option east of the pass, with seasonal water from meltwater streams.
• Sahale Glacier Camp (6 tent platforms, ~9.5 km from trailhead): Perched on rock at 2,240 m (7,250 ft) beside the glacier. Water from snowmelt only; bear canisters required. One of the most dramatic high camps in the Pacific Northwest.
• Basin Creek Camp (4 sites, ~13 km from trailhead): Forested old-growth setting along Basin Creek — a natural mid-traverse camp.
• Cottonwood Camp (4 sites, ~14.5 km from trailhead): Lower Stehekin River valley, near the NPS shuttle road end.

Backcountry permits cost $7 USD (~€6.50) per person per night. Bear canisters are required at all sites and can be rented at the Marblemount Wilderness Information Center for approximately $5 (~€4.60) per trip. At the Stehekin end, North Cascades Lodge at Stehekin offers motel-style rooms from approximately $170 USD (~€157) per night — advance booking is essential throughout July and August.

Getting There & Back

The trailhead has no public transit access. Driving or arranging a car shuttle is required.

• By car (trailhead start): From Seattle-Tacoma International Airport (SEA), drive approximately 3 hours north on I-5 to Burlington, then east on State Route 20 to Marblemount, then 23.1 miles (37 km) on Cascade River Road to the trailhead parking lot. The gravel section is passable in a standard vehicle but slow.
• Car shuttle (full point-to-point traverse): Leave a second vehicle in Chelan (~3.5 hours from Seattle), then catch the Lady of the Lake ferry up-lake to Stehekin. The NPS seasonal shuttle bus connects Stehekin to Cottonwood Camp, reducing the final walking stage to under 5 km if desired.
• By floatplane: Kenmore Air operates scenic floatplane services from Seattle to Stehekin (approximately $250–$300 USD / €230–€277 one way), a practical option for one-way traversers finishing at Lake Chelan.

Permits & Fees

• Day hiking: No permit required. North Cascades National Park charges no vehicle entrance fee — one of the few major US national parks with free admission.
• Overnight backcountry: A wilderness permit is required for all overnight camping. Permits are limited; reserve in advance via Recreation.gov. Cost: $7 USD (~€6.50) per person per night plus a $6 USD (~€5.50) non-refundable reservation fee per booking.
• Walk-up permits: Available from the Marblemount Wilderness Information Center for the following day on a first-come, first-served basis. Arrive early — Sahale Glacier Camp fills weeks in advance throughout July and August.
• Bear canisters: Required at all backcountry sites. Rentals available at Marblemount WIC for ~$5 (~€4.60) per trip. No campfires permitted anywhere on the route.

Gear & Packing List

Cascade Pass sits in a high-alpine environment where conditions can shift rapidly. Even on a clear August day, temperatures at the pass can be 10–15 °C cooler than the valley floor, and afternoon thunderstorms develop quickly. Pack accordingly regardless of the forecast.

Essential gear for the day hike:

• Layering system: moisture-wicking base, insulating mid-layer, waterproof shell
• Trekking poles — strongly recommended for 30+ switchbacks on the ascent and the steep Sahale Arm descent
• Sun protection: SPF 50+ sunscreen, polarised sunglasses, wide-brim hat (UV exposure is intense at altitude, amplified by snow reflection through July)
• At least 2 litres of water — no reliable water source on the main trail until the upper meadows near the pass
• High-calorie snacks and trail meals — our guide on how many calories you need hiking a full day helps you plan fuel correctly for strenuous alpine terrain
• Map and compass (cell service is unavailable throughout the backcountry)
• Microspikes or ice axe for early-season Sahale Arm travel before late July

For multi-day traverses, pack weight is critical on the steep 518 m approach. An ultralight pack pays real dividends here. Top recommendations for Cascade Pass:

• Hyperlite Mountain Gear 2400 Windrider — ultralight DCF construction at 38L, ideal for 2–3 night trips with disciplined packing; excels in wet Pacific Northwest conditions
• Hyperlite Mountain Gear 3400 Windrider — the 54L version for the full Stehekin traverse or colder September conditions requiring extra insulation
• Osprey Aether 65 — a full-featured 65L pack with traditional frame and load-lifter suspension for hikers who prefer a heavier, structured carry
