Pacific Northwest Trail 03 Washington

The Pacific Northwest Trail 03 Washington is the longest state segment of the 1,200-mile (1,930 km) National Scenic Trail spanning the United States' Pacific Northwest — a point-to-point route stretching roughly 700 miles (1,130 km) from the Idaho border to Cape Alava. With cumulative elevation gain exceeding 130,000 ft (39,600 m) and difficulty ranging from easy to strenuous, it crosses North Cascades National Park, the Hoh Rain Forest, and 73 miles of wild Pacific coastline.

About the Pacific Northwest Trail 03 Washington

The Pacific Northwest Trail (PNT) was conceived by hiker and author Ron Strickland in 1970, who envisioned a continuous route linking the Continental Divide in Montana to the Pacific Ocean in Washington. After nearly four decades of volunteer work by trail crews and land managers, Congress officially designated the PNT as a National Scenic Trail in 2009 through the Omnibus Public Lands Management Act, signed by President Obama on March 30 of that year. The Pacific Northwest Trail Association (PNTA), founded by Strickland in 1977, continues to manage and maintain the route.

Washington's segment — designated Section 03 in PNTA planning documents — is the trail's defining chapter. It spans the full breadth of Washington State from the Okanogan Highlands in the east to Cape Alava on the wild Olympic Coast in the west. Along the way, hikers cross three distinct mountain ranges, descend into the Methow Valley, navigate the glacier-carved corridor of North Cascades National Park, and traverse two commercial ferry crossings across Puget Sound. No other segment of the PNT packs this variety into a single continuous walk.

The trail is open to hikers, equestrians, and in some segments mountain bikers. Thru-hikers of the Washington section alone should budget 8–10 weeks; those tackling the full 1,200-mile PNT from Glacier National Park typically spend 80–100 days on trail. The PNTA estimates fewer than 100 hikers complete the full trail in any given year, making the PNT far less crowded than the Pacific Crest Trail or the Appalachian Trail. For those seeking a genuine wilderness experience without the crowds, the Washington section is one of the most rewarding and underrated long-distance walks in the United States.

Route Overview & Stages

The Washington section is typically broken into seven broad segments, each with its own character and challenge level. Most hikers travel east to west — Idaho border to Cape Alava — following the official PNTA direction. Distances below are approximate; the PNTA refines the route annually as trail relocations are completed.

Highlights & Points of Interest

• Cathedral Pass, Pasayten Wilderness — The highest point on the entire Pacific Northwest Trail, Cathedral Pass sits at the edge of the Pasayten Wilderness in the northern Cascades. Views stretch south toward the Stuart Range and north into Canada, with wildflower meadows blanketing the approach in July and August.
• North Cascades National Park — Often called the "American Alps," this remote park sees fewer than 30,000 visitors per year. The PNT crosses dozens of braided glacial streams and passes beneath peaks carrying over 300 active glaciers, including the Boston and Sahale Glacier complex near Cascade Pass.
• Ross Lake National Recreation Area — The turquoise waters of Ross Lake, backed by steep forested ridges, provide some of the most dramatic backcountry camping on the route. Boat taxis operating on the lake shorten resupply runs to the settlement of Diablo along SR-20.
• Mount Baker Wilderness — Ringed by active volcanic terrain, Mount Baker (3,286 m / 10,781 ft) dominates the skyline as the PNT winds through old-growth stands of Douglas fir and western red cedar. The area holds one of the highest annual snowfall records in North America, making late-season timing critical for this segment.
• Fidalgo & Whidbey Island Ferry Crossings — One of the PNT's most distinctive features: hikers board Washington State Ferries at Anacortes, cross to Fidalgo Island, then transfer to Whidbey Island before a final ferry to Port Townsend on the Olympic Peninsula. No other major long-distance trail in the US includes commercial ferry crossings as a core part of the route.
• Olympic National Park — The Olympics encompass three distinct ecosystems: glaciated mountains, old-growth temperate rain forest, and 73 miles of undeveloped Pacific coastline. The PNT traverses all three, climbing through the Bailey Range before descending into the Hoh Rain Forest.
• Hoh Rain Forest — Averaging 140 inches (355 cm) of rain per year, the Hoh is carpeted in moss-draped greenery and Sitka spruce trees over 200 feet tall. The PNT passes through on the approach to the coast — a surreal shift from alpine scree to ancient temperate jungle in under two hiking days.
• Cape Alava — The westernmost point of the contiguous United States and the western terminus of the Pacific Northwest Trail. Hikers arriving here stand at the end of a full continental crossing, greeted by sea stacks, tidepools, and the crash of Pacific breakers on a coastline with zero vehicle access.

Best Time to Hike the Pacific Northwest Trail 03 Washington

Snow depth is the primary planning constraint on the Washington section. The Okanogan Highlands and Pasayten Wilderness typically hold significant snowpack through early June, while North Cascades passes and the Mount Baker Wilderness can remain blocked into late June in heavy snow years. Planning resources from the Pacific Northwest Trail Association recommend starting no earlier than mid-June for hikers tackling the high-elevation segments — and as of 2026, above-average snowpack years have pushed that window to early July for the most exposed Cascades passes.

July is the single best month to hike the Washington section. By July, all but the most exposed passes are snow-free, wildflowers peak in the Pasayten Wilderness and North Cascades, river crossings drop from spring flood levels, and the Olympic Peninsula coast reaches its sunniest stretch of the year. Average high temperatures in Port Angeles reach 19°C / 66°F in July, and even the perpetually wet Hoh Rain Forest sees its driest period.

• June: Snow on Pasayten and Cascade passes; suitable only for experienced snow travellers carrying an ice axe and crampons. The coastal section and lower Okanogan Highlands are accessible and very quiet.
• July–August: Prime window. High passes open, daylight exceeds 15 hours in early July, optimal wildlife sightings including black bear and mountain goat. Wildfire smoke can affect eastern Washington in August, reducing air quality and visibility on exposed ridges.
• September: Excellent through mid-month. Shorter days, first frosts above 1,500 m, dramatically reduced hiker traffic. Vivid fall colour spreads through the Okanogan Highlands from mid-September onward.
• October–May: Not recommended for thru-hikers. Heavy rainfall blankets the Olympic Peninsula — the Hoh averages over 250 mm in November alone — and high-pass snow returns rapidly once temperatures drop.

Practical Information

Accommodation

The Washington section is primarily a backcountry trail with wilderness camping as the norm. Within North Cascades National Park and Olympic National Park, designated campsites with bear cables or bear boxes are required for overnight use. Outside the parks, dispersed camping is permitted throughout national forest lands under standard Leave No Trace practices.

Key resupply towns offer lodging at a range of price points:

• Republic, WA — Small motels from around €55–70/night; a full grocery store and pharmacy make it the best resupply stop in eastern Washington.
• Winthrop, WA — Hostel-style bunkhouses from €35–50/night; a well-stocked gear shop and post office accept mail drops into the North Cascades resupply gap.
• Sedro-Woolley, WA — Motel rooms from €65–80/night; the last major town before the Puget Sound crossings and Mount Baker approach.
• Port Angeles, WA — Hotels and motels €80–150/night; the Olympic Peninsula gateway with a full outfitter, hospital, ferry to Victoria BC, and Olympic National Park visitor centre.

Getting There & Back

The eastern trailhead at the Washington/Idaho border is most easily reached via Spokane International Airport (GEG), approximately 90 miles (145 km) east — roughly a 90-minute drive. Car rental from Spokane is the standard option; no scheduled public transport serves the remote Okanogan Highlands trailhead directly.

The western terminus at Cape Alava is accessed via the Lake Ozette Trailhead in Olympic National Park, reachable from Port Angeles in approximately 2 hours (80 miles / 130 km) by car. Seattle-Tacoma International Airport (SEA) is the nearest major international hub, with ferry connections from Seattle to the Olympic Peninsula — total travel time around 3–4 hours without a personal vehicle using the Washington State Ferry system.

Permits & Fees

Camping within North Cascades National Park requires a free backcountry permit, available at the Wilderness Information Center in Marblemount or at park visitor centres. Walk-up permits are generally available; the Cascade Pass area fills on busy July weekends, so an early-morning arrival is advisable.

Within Olympic National Park, backcountry permits cost USD $8 per night plus a one-time USD $6 reservation fee per trip. The Olympic Coast segment — including the Cape Alava approach — uses assigned campsites that sell out for July and August well in advance; book through recreation.gov as early as possible.

A Northwest Forest Pass (USD $30/year or $5/day) is required for vehicle parking at most national forest trailheads. Hikers arriving by public transport or ferry are exempt from this requirement.

Gear & Packing List

A trail this long and varied demands gear capable of handling everything from the dry shrub-steppe of eastern Washington to the saturated Olympic coast. Waterproof everything — even in July, the Hoh Rain Forest and the coastal section average more than 10 rain days per month, and storms can roll in from the Pacific with little warning.

Pack capacity in the 50–70 litre range balances food carry for long resupply gaps — the North Cascades segment has no town access for roughly 100 miles — with manageable daily weight. The Osprey Aether 65 suits heavier loads with its integrated rain cover and load-transfer suspension; ultralight hikers favour the Zpacks Arc Haul Ultra 50L or the Hyperlite Mountain Gear 3400 Windrider to keep base weight under 5 kg and total pack weight manageable across a 10-week carry. For a full comparison of lightweight pack options before committing, see the Best Ultralight Backpacks 2026 guide.

• Navigation: Paper maps and a baseplate compass are essential — cell coverage is absent for long stretches through the North Cascades and Olympic backcountry. Download the PNTA's digital maps to a GPS device as a backup, and carry a personal locator beacon on remote sections.
• Bear protection: A bear canister is required in certain North Cascades zones and strongly recommended throughout. Bear spray is standard practice in eastern sections where grizzly bear presence has been documented in recent decades.
• Water treatment: Glacial streams and mountain springs are abundant throughout, but filtration or chemical purification is required — giardia is present in even remote sources.
• Rain gear: A full waterproof shell with fully taped seams is non-negotiable for the Olympic Peninsula. Gore-Tex or equivalent membrane fabrics substantially outperform DWR-only hardshells in the sustained multi-day rain common on the coast.
• Trekking poles: Highly recommended. River crossings, lingering snow on early-season passes, and coastal driftwood scrambles make poles a genuine safety tool, not merely a comfort item.
• Food planning: With 8–10 weeks on trail and 25–30 km days, caloric density directly affects pack weight. The how many calories you need hiking a full day guide walks through the calculation before you finalise your food strategy.

Similar Trails You Might Like

If the Washington section of the Pacific Northwest Trail appeals to you — its point-to-point structure, long alpine passes, and dramatic finish at a wild Pacific coast — these trails share similar qualities. For iconic American canyon contrasts, the rim-to-rim combination of the South Kaibab Trail and North Kaibab Trail in Grand Canyon National Park delivers a demanding multi-day traverse with jaw-dropping elevation change. The Clouds Rest Trail and Panorama Trail in Yosemite offer excellent day-hike introductions to Sierra Nevada granite terrain. Zion's Hidden Canyon suits shorter schedules with its technical slot-canyon approach. For an international adventure with similarly remote mountain character, the Theth to Valbona hike in Albania delivers dramatic mountain passes and genuine wilderness with a fraction of the foot traffic found on comparable European routes.

Frequently Asked Questions

When is the best time to hike the Pacific Northwest Trail Washington section?
July is the single best month. High alpine passes clear of snow by early July, wildflowers reach peak in the Pasayten Wilderness and North Cascades, and the Olympic Peninsula coast hits its driest and sunniest stretch of the year. Snow typically blocks the highest passes through June, and heavy autumn rains return to the Olympic Peninsula by October. The July–August window offers the most reliable conditions across all seven stages.

How difficult is the Washington section of the PNT?
Difficulty ranges from easy on the Puget Sound island crossings and lower valley sections to genuinely strenuous on the alpine passes of the Pasayten Wilderness and North Cascades National Park. Navigation is the biggest challenge — the PNT is not waymarked to PCT or AT standards, and several segments require confident map-and-compass skills. Prior off-trail experience and solid navigation ability are strongly beneficial for the central mountain stages.

How many kilometres per day should I plan?
Most thru-hikers average 20–30 km (12–19 miles) per day. The Okanogan Highlands allow faster progress on gentle ridges and dirt roads, while the North Cascades can slow even fit hikers to 15–18 km on technical days with heavy elevation gain. Budget a minimum of 8 weeks for the full Washington section, with 10 weeks providing room for weather holds and rest days.

What accommodation options exist along the route?
The trail is primarily a wilderness camping route, with designated backcountry campsites inside North Cascades and Olympic National Parks. Trail towns — Republic, Winthrop, Sedro-Woolley, Port Angeles — provide motels and hostel-style lodging from around €35–150 per night and serve as resupply hubs. Mail drops sent ahead to Winthrop are popular for the North Cascades segment, which has no town access for roughly 100 miles.

Do I need a permit to hike the Washington section of the PNT?
Backcountry permits are required for camping in both North Cascades National Park (free, walk-up at the Marblemount Wilderness Information Center) and Olympic National Park (USD $8/night plus a USD $6 reservation fee). The Olympic Coast — including the Cape Alava terminus — uses assigned campsites that fill months in advance for summer dates; book at recreation.gov early. A Northwest Forest Pass (USD $30/year) is required for vehicle parking at national forest trailheads.
