Hayden Pass Trail

The Hayden Pass Trail is a 13 km point-to-point trail in Olympic National Park, Washington, United States, gaining 580 m of elevation to reach Hayden Pass at 1,788 m above sea level. Rated strenuous, it is a spectacular trans-mountain wilderness crossing connecting the Elwha River valley to the Dosewallips River valley through ancient old-growth forest and sweeping subalpine meadows.

About the Hayden Pass Trail

Deep in the heart of Olympic National Park, the Hayden Pass Trail serves as one of the few high-altitude crossings that bisects the Olympic Mountains from north-west to south-east. It links two of the park's most celebrated river corridors — the Elwha River to the north-west and the Dosewallips River to the south-east — separated by a jagged ridge culminating at Hayden Pass (1,788 m / 5,865 ft).

As part of the Regional Walking Network, the trail functions as a vital link in longer wilderness itineraries across the Olympic Peninsula. Backpackers completing multi-day traverses of Olympic National Park use Hayden Pass as a key waypoint, transitioning from the lush, rain-soaked Elwha valley through old-growth forest into exposed tundra and subalpine terrain near the pass before dropping steeply into the Dosewallips drainage. The character of this crossing — two contrasting valleys joined by a high mountain pass — echoes classic wilderness traverse routes worldwide, such as the Theth to Valbona hike in Albania, albeit set in a distinctly Pacific Northwest wilderness context.

Managed by the U.S. National Park Service, the route runs entirely through designated Olympic Wilderness, where no mechanised equipment is permitted and all overnight parties must carry a wilderness permit. Access exists only at either end — the Elwha River Trail junction to the north-west and the Dosewallips River Trail junction to the south-east — making this one of the more committing routes on the peninsula.

The point-to-point format requires a vehicle shuttle or out-and-back approach; most backpackers combine Hayden Pass Trail with sections of one or both river trails to form a multi-day traverse. The elevation profile is sharply asymmetric: 580 m of gain climbing from the Elwha side, followed by a formidable 1,384 m descent to the Dosewallips. Most parties travel Elwha-to-Dosewallips, tackling the punishing descent while legs are still relatively fresh rather than saving it for the end of a long day.

Route Overview & Stages

The route below follows the preferred Elwha River Trail junction → Hayden Pass → Dosewallips River Trail junction direction. All distances are cumulative from the Hayden Pass Trail junction with the Elwha River Trail.

Stage 1 — Elwha Junction to Hayden Creek Camp (4 km, +200 m): The trail leaves the Elwha River Trail and enters old-growth rainforest, following Hayden Creek upstream through Douglas firs exceeding 50 m and western red cedars with base diameters of 2–3 m. The creek must be forded at least once — expect knee-deep water in July from peak snowmelt. Gradient is gentle throughout, making this the most accessible stretch. Hayden Creek Camp at 4 km offers bear wires and a pit toilet beside the creek.

Stage 2 — Hayden Creek Camp to Hayden Pass (5 km, +380 m): The demanding climb begins here, gaining elevation via long switchbacks. Forest transitions to open subalpine terrain above 1,400 m. By late July and August, slopes are carpeted with lupine, Indian paintbrush, beargrass, and valerian. The final kilometre to the pass crosses exposed talus and tundra — trekking poles are strongly recommended. Hayden Pass at 1,788 m is a sharp notch in the ridge with 360-degree views of the Olympic interior.

Stage 3 — Hayden Pass to Dosewallips Junction (4 km, −1,384 m): The steepest and most demanding section of the route. The trail loses 1,384 m in just 4 km — a sustained gradient that demands careful footing and reliable poles. The path alternates between open slopes and dense forest canopy before depositing hikers at the wide, flat Dosewallips River Trail at approximately 564 m elevation.

Highlights & Points of Interest

• Hayden Pass Summit (1,788 m) — The trail's defining moment: a sharp ridge notch opening panoramic views of the Olympic interior, the Bailey Range to the west, and on clear days the distant Cascades to the east.
• Hayden Creek Old-Growth Stand — The lower trail corridor preserves some of the finest old-growth forest on the Olympic Peninsula: Douglas firs exceeding 50 m, red cedars with 3 m base diameters, and an understorey thick with sword ferns and wood sorrel.
• Subalpine Wildflower Meadows (1,400–1,700 m) — Seasonal wildflower displays peak in late July and August: glacier lilies, purple asters, and sprawling fields of lupine and Indian paintbrush carpet the open slopes just below timberline.
• Hayden Creek Camp — The designated wilderness campsite 4 km from the Elwha junction at approximately 800 m elevation. Flat tent pitches beside the creek with bear wire infrastructure make this the logical first-night stop.
• Elwha River Junction — The northern entry connects to the Elwha River Trail and the restored Elwha River watershed — site of the two largest dam removals in U.S. history (completed 2014), a recovering ecosystem now drawing wildlife back to the lower river.
• Alpine Tarns below the Pass — Small snowmelt ponds just below the summit ridge persist through August, reflecting surrounding peaks in calm, clear conditions.
• Dosewallips River Valley Floor — The broad, glacially carved valley at the southern end supports Roosevelt elk, black-tailed deer, and black bears. Early-morning arrivals regularly encounter wildlife along the river corridor.
• Wildlife Corridor — The crossing traverses critical habitat for Roosevelt elk, a subspecies endemic to the Olympic Peninsula and fully protected within Olympic Wilderness.

Best Time to Hike the Hayden Pass Trail

The trail is seasonal due to its high-elevation pass crossing. Hayden Pass typically holds snow through early July, concentrating reliable hiking into the window from mid-July to late September. As of 2026, NPS trail condition reporting confirms this seasonal pattern is consistent with historical norms.

• Mid-to-Late July: Snow clearing from the pass. Wildflowers beginning below 1,400 m. Creek crossings high and cold from peak snowmelt — knee-deep fords expected. Active mosquitoes in the lower forest; carry a head net.
• August: Peak conditions across all metrics. The pass is fully clear of snow, wildflower displays reach their best between 1,400 m and 1,700 m, creek levels are manageable for crossing, and daytime temperatures reach 18–22°C at lower elevations. Daylight extends past 20:00 in early August. August is the single best month to hike the Hayden Pass Trail.
• September: Excellent visibility and comfortable climbing temperatures. Crowds thin sharply after Labor Day (first Monday of September). Autumn colour begins in the subalpine zone by mid-September. First light frosts are possible above 1,500 m by late month.
• October onwards: Not recommended. Early snowfall can close the pass without warning and NPS does not maintain this route after the summer season ends.

Always check the Olympic National Park wilderness trail conditions page before departure — conditions at the pass change quickly, and NPS updates trail status throughout the hiking season.

Practical Information

Accommodation

The Hayden Pass Trail runs entirely through Olympic Wilderness — there are no huts, lodges, or staffed refuges on the route. All overnight stays require wilderness camping.

• Hayden Creek Camp — Designated wilderness camp 4 km from the Elwha junction at approximately 800 m elevation. Bear wires and a pit toilet provided. No additional fee beyond the wilderness permit.
• Near-pass camping — Some parties camp in sheltered hollows just below the pass on the Elwha side. No facilities at this informal site; bear canister required and mandatory throughout Olympic Wilderness.
• Dosewallips Campground — Basic camping at the southern end (now located 4 km from the road closure). Vault toilet on site. No nightly fee beyond the wilderness permit covering backcountry use.

Wilderness permit cost (2026): approximately $8 per person per night (around €7.30 at June 2026 exchange rates), plus a one-time $6 (€5.50) reservation processing fee when booking in advance through Recreation.gov. Advance booking is strongly recommended for August weekends, when daily quotas at the Elwha entry point fill quickly.

Getting There & Back

Because this is a point-to-point trail, most hikers arrange a vehicle shuttle or use a commercial shuttle service between the two trailheads. The Elwha and Dosewallips trailheads are approximately 120 km apart by road.

Elwha River Trailhead (northern / recommended start): From Port Angeles, take US-101 west approximately 18 km to the Olympic Hot Springs Road junction, then drive south 14 km to the Elwha trailhead parking area. Port Angeles is the nearest service town with fuel, resupply, and accommodation options. From Seattle-Tacoma International Airport (SEA) — the nearest major international airport — allow approximately 3 hours by car, including the Edmonds–Kingston ferry crossing or the Hood Canal Bridge route.

Dosewallips Trailhead (southern / end point): From US-101 near Brinnon, take Dosewallips Road (Forest Road 2610) inland. A long-standing washout at the 6 km mark requires parking at the road closure and walking an additional 4 km on the former road surface to reach the wilderness trailhead. No public transit serves this access point. A vehicle shuttle between the two trailheads takes approximately 1 hour 45 minutes by road.

Permits & Fees

• Wilderness Permit: Required for all overnight stays in Olympic Wilderness. Reserve in advance via Recreation.gov or self-issue at trailhead kiosks, subject to daily quotas at the Elwha entry point during August.
• Bear canister: Mandatory throughout Olympic Wilderness for all food and scented items. Bear wires at Hayden Creek Camp supplement but do not replace this requirement.
• Park entrance fee: The Elwha trailhead does not pass through a fee station, so the standard Olympic National Park vehicle entry fee ($35 / €32) does not apply at this access point. An America the Beautiful Annual Pass ($80 / €73) waives advance reservation processing fees.
• Campfire restriction: Prohibited above 1,500 m and at Hayden Creek Camp. Stove cooking only throughout the route.

Gear & Packing List

The asymmetric elevation profile — 580 m of gain followed by 1,384 m of steep descent — places unique demands on gear selection. Trekking poles are arguably the most important piece of equipment on this route; the Dosewallips descent places sustained impact on knees and ankles over 4 relentless kilometres. For backpackers prioritising weight, the Hyperlite Mountain Gear 2400 Windrider (540 g) handles a 2-night load comfortably in Olympic's famously wet conditions. Parties carrying food for 3+ nights may prefer the larger HMG 3400 Windrider for the additional volume. Hikers who prioritise load transfer and hip-belt support — particularly relevant on that steep Dosewallips descent — will find the Osprey Aether 65 a reliable benchmark for comfort on demanding terrain.

Calorie planning for strenuous alpine days is covered in detail in How Many Calories Do You Need Hiking a Full Day? — essential reading before provisioning a traverse with this elevation profile.

Essential kit for Hayden Pass Trail:

• Backpack 40–65 L with waterproof liner or dedicated rain cover (Olympic weather is reliably wet at any elevation)
• Trekking poles — non-negotiable for the 1,384 m Dosewallips descent
• Waterproof trail runners or mid-cut boots (creek fords guaranteed in July; muddy sections year-round)
• Mandatory bear canister (Wild Ideas Bearikade, BV500, or equivalent approved model)
• 3-season sleeping bag rated to at least −5°C (temperatures at the pass drop sharply after sunset)
• Freestanding tent (pitches at Hayden Creek Camp are uneven; trekking-pole shelters are unreliable here)
• Water filter or purification tablets (Hayden Creek is a reliable source but treat all water)
• Insulating mid-layer and waterproof shell (Olympic weather can change without warning at any elevation)
• Head net for the lower forest sections in July when mosquitoes are active
• Sunscreen and sunglasses for the exposed pass and tundra sections above 1,600 m

Frequently Asked Questions

When is the best time to hike the Hayden Pass Trail?
August is the single best month. Hayden Pass is reliably clear of snow, wildflower displays peak between 1,400 m and 1,700 m, creek crossings are at safe levels, and daylight hours remain long. Mid-July is the earliest practical window, and late September is the last reliable date before early snowfall becomes a risk at 1,788 m. Always verify current conditions on the NPS trail conditions page before departure.

How difficult is the Hayden Pass Trail?
The trail is rated strenuous. The 580 m gain to Hayden Pass (1,788 m) is achievable for fit hikers at a steady pace, but the 1,384 m descent from the pass to the Dosewallips River Trail in just 4 km is the real physical challenge — sustained steep terrain over rooted and rocky ground. Well-fitting boots, reliable trekking poles, and strong knees significantly reduce the strain on the descent section.

How far do you hike per day on this trail?
Most parties split the 13 km over 2 days: Day 1 covers the 4 km to Hayden Creek Camp with a modest 200 m gain; Day 2 tackles the summit climb and steep descent to Dosewallips while legs are rested. Fit hikers complete the full crossing in a single long day of 6–8 hours. An overnight stay at Hayden Creek Camp allows a more relaxed pace through the wildflower meadows on the climb to the pass.

What accommodation is available on the trail?
The route passes entirely through Olympic Wilderness — there are no huts or staffed facilities anywhere on the trail. Hayden Creek Camp (4 km from the Elwha junction, approximately 800 m elevation) is the only designated campsite, with bear wires and a pit toilet. A bear canister is mandatory throughout Olympic Wilderness for all food storage. Advance reservation via Recreation.gov is strongly recommended for August, when quotas at the Elwha trailhead fill quickly.

Do I need a permit to hike the Hayden Pass Trail?
A Wilderness Permit is required for all overnight use in Olympic Wilderness. The permit costs approximately $8 per person per night (around €7.30) plus a one-time $6 reservation processing fee when booking in advance. Day hikers do not require a permit. Permits are available via Recreation.gov or by self-issue at the trailhead kiosk, subject to daily quotas. Campfires are prohibited above 1,500 m and at all designated campsites on this route.
