Gray Wolf Pass Trail

The Gray Wolf Pass Trail is a 5 km point-to-point trail in Washington State, United States, climbing from the Dosewallips River Trail to Gray Wolf Pass at 1,875 m (6,150 ft) and gaining approximately 670 m of elevation. Managed by the U.S. National Park Service within Olympic National Park, this challenging alpine route delivers old-growth conifer forest, wildflower meadows, and sweeping ridge-top panoramas across the northeast Olympic Peninsula.

About the Gray Wolf Pass Trail

Tucked deep inside the northeast corner of Olympic National Park, the Gray Wolf Pass Trail is a 5 km point-to-point route linking the Dosewallips River Trail to the 1,875 m (6,150 ft) summit of Gray Wolf Pass. Managed by the U.S. National Park Service and classified as part of the Regional Walking Network (RWN), the trail serves as a critical connecting segment in the Olympic Peninsula's backcountry network — joining the Dosewallips River drainage on the south side of the pass with the Upper Gray Wolf River valley on the north.

Though 5 km is modest on paper, the Gray Wolf Pass Trail is anything but a casual outing. It gains approximately 670 m of elevation across those kilometres, producing sustained grades that frequently exceed 15%, particularly in the upper switchback zone below the pass. That concentrated ascent earns the trail a reputation as one of the more demanding approaches in the northeast Olympics. Hikers carry the full weight of the pass experience in their legs long before arriving at the wide, windswept saddle.

The trail transitions through three distinct ecological zones. The lower section threads through ancient old-growth conifer forest — Douglas fir and western hemlock with trunk diameters reaching 2 metres — sheltered, mossy, and perpetually damp from the heavy precipitation the Olympic Mountains receive. The middle section breaks into subalpine terrain as the forest thins, replaced by mountain heather, huckleberry, and the first long-range views across the Dosewallips valley. The upper section crosses open rocky ground below the pass itself, fully exposed to weather rolling in off the Pacific.

Wildlife is abundant throughout the corridor. Olympic marmots (Marmota olympus), found nowhere else on Earth, inhabit the rocky slopes near the pass and announce your arrival with sharp warning whistles. Black-tailed deer graze the subalpine meadows in summer. Black bears patrol the lower forest zone. Roosevelt elk — the iconic ungulate of the Olympic Peninsula — roam the broader Dosewallips corridor and are most visible at dawn and dusk in open meadows.

As a segment of longer loops including the Gray Wolf–Dosewallips–Cameron Circuit and the Grand Loop, this 5 km climb carries hikers from the sheltered Dosewallips valley over the spine of the Olympic Range and connects them with the Gray Wolf River drainage, which stretches 22+ km northward toward Olympic National Forest trailheads near Sequim. The pass is a true geographic pivot point in the Olympic backcountry, and crossing it feels exactly like that — a decisive passage between two worlds.

Dogs are not permitted on this trail, in line with Olympic National Park's wildlife protection policies for its wilderness zones.

Route Overview & Stages

The Gray Wolf Pass Trail runs 5 km northward and upward from the Dosewallips River Trail junction to Gray Wolf Pass. The elevation profile is continuously uphill with no significant flat sections. Most hikers arrive via the Dosewallips Trailhead, reached from Brinnon via Dosewallips Road, and tackle the pass segment as part of a multi-day backpacking loop. Allow 2.5 to 4 hours for the one-way ascent depending on pack weight and fitness.

Total: 5 km  |  Elevation gain: ~670 m  |  Highest point: Gray Wolf Pass at 1,875 m (6,150 ft)

Highlights & Points of Interest

• Dosewallips River Trail Junction — The starting point of the Gray Wolf Pass Trail proper, where the route forks north from the Dosewallips corridor. The junction sits deep in conifer forest with the river audible below; fill water bottles here before the sustained climb begins.
• Ancient Old-Growth Forest — The lower 1.5 km passes through a primeval stand of Douglas fir and western hemlock, some specimens exceeding 2 metres in diameter and several hundred years in age. Moss carpets every surface and nurse logs host entire micro-ecosystems — a hallmark of the UNESCO World Heritage-listed Olympic ecosystem.
• Lower Switchback Series — Beginning around km 1.5, a demanding sequence of switchbacks carries the trail rapidly up the valley wall. These are the most physically intense kilometres on the route and offer the first filtered views of the Dosewallips drainage falling away below.
• Wildflower Meadows (~km 3) — At roughly 1,500 m elevation, the forest gives way to open subalpine meadows. Mid-July through August brings blooms of lupine, Indian paintbrush, avalanche lily, and spreading phlox — a vivid floral reward after the shaded climb below.
• Alpine Tarns — In the upper basin just below the pass, seasonal tarns collect snowmelt and provide reliable water through August. These small, clear mountain lakes can be frozen or absent before mid-July in high-snow years and offer one of the trail's most photogenic rest spots.
• Gray Wolf Pass Summit (1,875 m / 6,150 ft) — The wide, windswept pass is the trail's highest point and geographic centrepiece. On clear days, views sweep northeast across the Olympic Range toward Port Angeles, the Strait of Juan de Fuca, and Vancouver Island, British Columbia.
• Olympic Marmot Colonies — The rocky slopes on both sides of the pass are prime habitat for the Olympic marmot (Marmota olympus), a species found nowhere else on Earth. Their sharp alarm calls are one of the defining sounds of a summer morning at altitude in the Olympics.
• Gateway to the Gray Wolf River Valley — Immediately over the pass on the north side, the trail descends into the Upper Gray Wolf River drainage — a separate, lush, and less-visited valley stretching 22+ km back to Olympic National Forest trailheads near Sequim. The descent is steep and dramatically different in character from the Dosewallips approach.

Best Time to Hike the Gray Wolf Pass Trail

Gray Wolf Pass sits at 1,875 m and typically holds snow until late June or early July. The accessible hiking season runs from early July through late September most years. As of 2026, Olympic National Park trail reports confirm this window remains reliable, though high-snow years can push the snow-free opening to mid-July. Check current conditions at the Olympic National Park wilderness trail conditions page before departure.

The single best month to hike is August. By August, snowfields have cleared from the pass and switchbacks in all but the heaviest snow years, the wildflower meadows are at peak bloom, creek crossings are manageable as snowmelt tapers off, and long Pacific Northwest daylight — sunsets after 8:30 PM through mid-August — allows unhurried ascents. Daytime temperatures at the pass average 10–18°C; nights drop to 2–5°C, making a 3-season sleeping bag essential for overnight trips.

• July: Snow patches commonly persist on the upper 1.5 km into early July. Carry microspikes before July 15. Wildflowers beginning. Creek crossings can run high from active snowmelt.
• August: Optimal conditions. Clear passes, peak wildflowers, stable weather windows, long days. Backcountry campsites fill quickly — obtain permits early in the month.
• September: Crowds thin significantly after Labour Day. Huckleberry turns crimson across the subalpine slopes. Nights turn cold (0–3°C), afternoon thunderstorms become more frequent, and the first snow can dust the pass from late September onward.
• October–June: Not recommended without mountaineering skills, ice axe, and crampons. The pass can hold 3–5 metres of snow into June in heavy years.

Practical Information

Accommodation

The Gray Wolf Pass Trail is a true wilderness route with no huts, lodges, or permanent shelters along its length. All overnight accommodation is camping-based.

• Dose Meadows Backcountry Campsite — Located approximately 1 km below Gray Wolf Pass on the Dosewallips approach (around km 4 of this 5 km trail), this established wilderness site has designated tent pads and a food hang cable. Free with a valid backcountry permit. It fills quickly in August.
• Dosewallips Campground (trailhead) — A National Park Service drive-in campground with approximately 30 sites at $20/night (2026 rate, approx. €18). Pit toilets and bear boxes provided; no showers or hookups. First-come, first-served.
• Brinnon (20 km from trailhead) — The nearest town offers basic motel accommodation from ~$90–120/night (approx. €83–110) and a small grocery store for last-minute resupply before heading into the backcountry.
• Port Angeles (80 km from trailhead) — The hub for Olympic Peninsula visitors, with hostel dorm beds from ~$35/night (€32), mid-range hotels from $100–150/night (€92–138), and the Olympic National Park Visitor Center where backcountry permits are issued.

Getting There & Back

The Dosewallips Trailhead — the primary access point for the Gray Wolf Pass Trail — sits at the end of Dosewallips Road, approximately 25 km west of Brinnon, Washington.

• By car from Seattle (3–3.5 hours): Take the Washington State Ferry from Edmonds to Kingston (35-minute crossing), then drive US-101 west through Quilcene to Brinnon. Turn west onto Dosewallips Road — the final 10 km is unpaved forest road. A high-clearance vehicle is recommended; storm damage can close sections seasonally, so check conditions before departure.
• Nearest airport: Seattle-Tacoma International Airport (SEA) is approximately 3.5 hours from the trailhead including the ferry crossing. Rental cars are the practical choice; no direct shuttle currently operates from SEA to the trailhead.
• By public transit: Jefferson Transit Route 7 connects Quilcene and Brinnon on limited weekday schedules, but no public transport reaches Dosewallips Road itself — a rental car or arranged private shuttle covers the final 25 km.
• Shuttle services: Several outfitters based in Port Angeles and Sequim run point-to-point trailhead shuttles for the Gray Wolf–Dosewallips loop. Booking 4–6 weeks ahead is advisable for July and August dates.

Permits & Fees

• Olympic National Park Entry Fee: $35 per vehicle, valid for 7 days across all park entry points. The America the Beautiful Annual Pass ($80/year) covers entry to all U.S. national parks and federal lands and pays for itself in two park visits.
• Backcountry Overnight Permit: Required for all camping within Olympic National Park wilderness. The permit is free but must be obtained in person at the Olympic National Park Wilderness Information Center in Port Angeles (360-565-3100) or at the Dosewallips Ranger Station when staffed. Walk-in self-registration at the trailhead kiosk is available when the station is closed.
• Northwest Forest Pass: Required for parking at the Dosewallips Trailhead — $5/day or $30/annual pass. Available at ranger stations and through the U.S. Forest Service.
• Dogs: Strictly prohibited on the Gray Wolf Pass Trail and throughout Olympic National Park wilderness. No exceptions.

Gear & Packing List

The Gray Wolf Pass Trail rewards a well-considered pack. Its 670 m of elevation gain across 5 km means every kilogram translates directly into effort on the switchbacks — a compelling argument for going as light as possible without sacrificing safety. Our Best Ultralight Backpacks 2026 guide covers the top options tested across Pacific Northwest terrain.

Recommended pack volume: 40–65 litres for 2–3 night trips; 20–30 litres for a supported day hike from a base camp at Dose Meadows.

• Overnight pack: Osprey Aether 65 — a proven workhorse for multi-day Olympic Peninsula backpacking, with a well-fitted suspension that transfers heavy loads efficiently on sustained steep terrain.
• Ultralight overnight pack: Zpacks Arc Haul Ultra 50L — carbon-framed Dyneema construction cuts base weight dramatically; ideal for the relentless 670 m climb when every gram counts.
• Day hike or summit-bid pack: Hyperlite Mountain Gear 2400 Windrider — fully waterproof Dyneema build handles Olympic rain without a pack cover; excellent for fast ascents from a base camp at Dose Meadows.
• Rain shell: Non-negotiable. Olympic National Park receives 3,500–4,500 mm of annual precipitation and conditions at 1,875 m can change from blue sky to horizontal rain in under 30 minutes. Waterproof and breathable construction is the minimum acceptable specification.
• Footwear: Waterproof hiking boots with ankle support are recommended for the rocky upper terrain. Trail runners are viable in dry August conditions but become treacherous on frost-covered or wet rock in September.
• Microspikes: Carry in July; pack optionally in August for early-season insurance. Upper switchback snowfields can persist well into summer in high-snow years.
• Navigation: Download offline maps before reaching the trailhead — Green Trails Map 136 (Tyler Peak) covers the pass area. Cell signal is non-existent throughout the backcountry zone.
• Water filtration: Mandatory. Fill at the alpine tarns below the pass and at the Dosewallips junction. For a fuelling strategy on a strenuous 670 m ascent, see our full-day hiking calorie guide for practical numbers.
• Bear canister or hang system: Required in designated Olympic National Park wilderness zones. Check requirements at the permit station; where not strictly required, an approved hang system is still expected.
• Insect repellent: Mosquitoes are active through July and August in the lower forest zone, particularly in the first 1.5 km from the Dosewallips junction.

Frequently Asked Questions

When is the best time to hike the Gray Wolf Pass Trail?

August is the single best month. Gray Wolf Pass sits at 1,875 m and typically retains snow until late June or early July. August delivers reliable snow-free conditions on the switchbacks and pass itself, wildflower meadows at peak bloom, manageable creek crossings as snowmelt tapers, and long Pacific Northwest daylight that allows unhurried ascents. Avoid October through June unless you have alpine snow-travel experience, an ice axe, and crampons.

How difficult is the Gray Wolf Pass Trail?

The trail is rated hard. Over 5 km it climbs approximately 670 m — a sustained gradient that frequently exceeds 15%, especially on the upper switchback section approaching the pass. Strong aerobic fitness and prior experience on steep mountain terrain are recommended. The route is not suitable for young children or hikers without waterproof gear, navigation skills, and backcountry experience. Carry microspikes before mid-July.

How long does the trail take and how far should I hike per day?

As a standalone 5 km ascent, most fit hikers complete the one-way climb in 2.5 to 4 hours depending on pack weight. With a full overnight load, budget 3.5 to 4 hours. The trail is typically hiked as part of a 3–5 day backpacking loop through the Olympic interior, where the Gray Wolf Pass segment occupies one half-day between Dose Meadows camp and the Upper Gray Wolf River valley on the far side.

Where can hikers sleep near the Gray Wolf Pass Trail?

The main backcountry option is Dose Meadows campsite, roughly 1 km below the pass — free with a backcountry permit. The Dosewallips Campground at the trailhead offers car camping at $20/night (approx. €18). For indoor accommodation, Brinnon (20 km away) has motels from approximately $90/night, and Port Angeles (80 km away) offers hostel dorms from around $35/night and the full range of hotel options.

Do I need a permit to hike the Gray Wolf Pass Trail?

Yes — two permits apply for overnight trips. Olympic National Park charges a $35 per-vehicle entry fee (valid 7 days). A free backcountry overnight permit is required for all wilderness camping and must be collected in person at the Wilderness Information Center in Port Angeles or at the Dosewallips Ranger Station.
