West Fork Humptulips Trail #806
The West Fork Humptulips Trail #806 is a 27-kilometre point-to-point trail in Olympic National Forest, Washington State, United States, gaining 213 metres of elevation over 2–3 days. Rated moderate-to-hard due to multiple unmaintained river fords and remote access, it threads through primeval old-growth temperate rainforest alongside the West Fork Humptulips River — delivering genuine backcountry solitude on the Olympic Peninsula within three hours of Seattle.
About the West Fork Humptulips Trail #806
Deep in the southwestern corner of the Olympic Peninsula, the West Fork Humptulips Trail #806 follows the West Fork of the Humptulips River through one of the most intact stretches of Pacific temperate rainforest remaining in the contiguous United States. Maintained by the U.S. Forest Service, Olympic National Forest, the trail stretches 27 kilometres (17 miles) from the Gorge Bridge Trailhead in the south to the Upper West Fork Humptulips Trailhead near Campbell Tree Grove in the north. The route is classified within the Regional Walking Network (RWN) — a designation reflecting its value as a significant multi-day wilderness corridor.
What sets this trail apart from busier Olympic destinations is the near-total absence of day-trip crowds. The river valley is narrow and hemmed in by the steep ridges of the Moonlight Dome Roadless Area to the east and the Colonel Bob Wilderness to the west. Towering Sitka spruce, western red cedar and Douglas fir form a canopy overhead, while ferns, mosses and wood sorrel carpet every surface below. Birdsong — Pacific wrens, varied thrushes, winter wrens — accompanies hikers continuously through the valley.
The defining challenge is honest: the West Fork Humptulips River has no footbridges, and the route fords the river multiple times. In high water conditions from November through June, these crossings require sound judgment and experience. River levels reliably moderate by late July, making the trail safely passable for most experienced backpackers from August onward. For anyone researching the best ultralight backpacks for multi-day trips, the persistently wet Pacific Northwest climate makes waterproof pack construction a genuine priority on this route.
Trail grades average 0–10% along the valley floor with short pitches approaching 20% near the upper section as the route climbs toward Humpnoochee Pass. The highest point on the trail sits at approximately 305 metres (1,000 ft) above sea level, making total elevation change modest by Pacific Northwest standards — the real physical demand comes from distance, cumulative river crossings and the inevitably wet conditions rather than sustained climbing.
Route Overview & Stages
The West Fork Humptulips Trail #806 is best hiked as a south-to-north point-to-point, beginning at the Gorge Bridge (Lower) Trailhead and finishing at the Upper West Fork Humptulips Trailhead near Campbell Tree Grove. A car shuttle between trailheads, approximately 25 km apart by forest road, is the standard logistics approach. An alternative entry at the Middle West Fork (Pete's Creek) Trailhead divides the trail cleanly at its natural midpoint for those wanting a shorter first stage.
| Stage | Distance | Elevation Gain | Highlights |
|---|---|---|---|
| Stage 1: Gorge Bridge TH → Pete's Creek Junction | 13 km | ~100 m | Old-growth riverside forest, first river fords, Gorge Creek cascade, broad gravel bars |
| Stage 2: Pete's Creek Junction → Upper TH (Campbell Tree Grove) | 14 km | ~113 m | Dense old-growth canopy, Humpnoochee Pass approach, Colonel Bob Wilderness views, Campbell Tree Grove |
Stage 1 (Day 1) follows the valley floor with minimal elevation change and delivers the most dramatic river scenery — broad gravel bars, ancient log jams and deep pools reflecting the old-growth canopy above. Expect 4–6 river crossings in this lower section, depending on seasonal water level. The Pete's Creek confluence at kilometre 13 marks the end of the lower segment and the primary backcountry camping zone.
Stage 2 (Day 2) transitions into denser, slightly higher forest before the trail crosses Forest Service Road 2204 and reaches the upper trailhead area adjacent to Campbell Tree Grove — a named stand of exceptional old-growth trees accessible by road for those who want a shorter out-and-back into the upper valley. This stage is slightly longer but crossings are fewer, and the valley floor steepens gently toward the pass.
Highlights & Points of Interest
- West Fork Humptulips River Gorge — Within the first 2 km, the trail runs directly above a narrow canyon where the river churns through carved basalt. Morning light filtering through the Sitka spruce canopy here is exceptional, and the sound of whitewater fills the gorge.
- Old-Growth Rainforest Stands — Sitka spruce and western red cedar exceed 60 metres in height through the lower valley. Individual trees over 500 years old are visibly common, identified by deeply furrowed bark and massive crown spread far above the trail.
- River Fords — The multiple unmaintained crossings of the West Fork Humptulips River are the trail's defining physical challenge and its greatest asset for solitude. In summer low water they run knee-to-thigh deep; they function as natural gatekeepers that keep crowds minimal year-round.
- Gorge Creek Tributary — A clear side stream at approximately kilometre 4, offering reliable cold drinking water (filter required) and a short scramble to a small waterfall tucked into the old-growth understory.
- Pete's Creek Confluence — At kilometre 13, Pete's Creek meets the main river at a flat, shaded clearing among giant conifers — the best overnight camping location on the entire route, with level ground and reliable water from the side stream.
- Moonlight Dome Roadless Area — The eastern ridge visible throughout much of the hike forms the western boundary of this protected roadless zone. Its intact status ensures the valley has no industrial intrusion and maintains functioning wildlife corridors for elk and bear.
- Campbell Tree Grove — The trail's northern terminus neighbours this celebrated old-growth stand, home to one of the largest individual western red cedars recorded in Washington State — a fitting endpoint to a journey through ancient forest.
- Colonel Bob Wilderness Ridgeline — On clear days in the upper section, the serrated ridgeline of the Colonel Bob Wilderness rises to the southwest above 1,500 metres, providing a dramatic alpine backdrop to the low-elevation valley below.
Best Time to Hike the West Fork Humptulips Trail #806
The Olympic Peninsula is one of the wettest regions in the contiguous United States — the western valleys average 2,500–3,800 mm of rainfall annually — and the West Fork Humptulips valley shares this climate fully. Timing around river levels and trail drainage is the primary planning factor.
July sees snowmelt tapering and river levels beginning to drop, but crossings often remain high and fast through mid-month. Early-July visits require experienced high-water fording skills and trekking poles; late July is more manageable in most years.
August is the single best month. River levels reach their annual low, crossing conditions are safest for the widest range of hikers, and the valley enjoys its longest windows of dry weather. Daytime temperatures in the valley sit between 18–24°C. Wildlife activity — Roosevelt elk herds, black-tailed deer, black bear — peaks in August as animals move down to lower-elevation meadows and river bars.
September remains an excellent choice. Visitor numbers are minimal and the forest begins its subtle fall transition. Rainfall increases from mid-month; carry a waterproof shell regardless of the forecast.
October through June: Not recommended for most hikers. The river can run bank-to-bank and several crossings become genuinely dangerous. As of 2026, the U.S. Forest Service advises checking current river conditions via the Olympic National Forest recreation information line before any off-season visit.
Practical Information
Accommodation
The West Fork Humptulips Trail #806 has no staffed huts, backcountry shelters or paid overnight infrastructure. All camping is dispersed within Olympic National Forest — hikers select their own sites, with no reservation system or quota in place. Leave No Trace principles apply: camp at least 60 metres from the river and any water source, pack out all waste.
The Pete's Creek area at kilometre 13 is the established backcountry camping zone, with flat ground among old-growth trees and reliable water from Pete's Creek. Sites are free of charge. For a shorter Day 1, the Gorge Creek area (approximately km 4) has informal flat spots but less shelter from wind and rain.
The nearest developed campground is Humptulips Campground on Forest Service Road 2204, approximately 5 km south of the lower trailhead. Operated by the U.S. Forest Service, sites cost approximately $18–$22 USD (roughly €16–€20) per night and include vault toilets; no hookups or showers.
Getting There & Back
The lower trailhead (Gorge Bridge) is accessed from Aberdeen, Washington: drive US Highway 101 north for 22 miles, then turn north on Donkey Creek Road / Forest Service Road 2204 and continue 8 miles to the trailhead parking area. Aberdeen sits approximately 2 hours 30 minutes by car from Seattle-Tacoma International Airport (SEA), the nearest major hub, served by all US carriers and multiple international routes.
The upper trailhead (Upper West Fork Humptulips) is reached by continuing north on FS Road 2204 approximately 17 miles past the lower trailhead junction. A car shuttle between the two trailheads — roughly 45 minutes on forest roads — is the standard logistics solution for a one-way through-hike. No public transit serves either trailhead.
Hikers without a shuttle vehicle can arrange a local shuttle from Aberdeen (ask at outdoor retailers in town) or hike the trail as an out-and-back from the lower trailhead, extending the round-trip to 54 km over 3–4 days. The Washington Trails Association trip reports are updated regularly by hikers and are the most reliable source for current FS Road 2204 conditions, which can be gated or blocked by fallen timber.
Permits & Fees
A valid Northwest Forest Pass is required for parking at the Pete's Creek Trailhead and Middle West Fork Trailhead. The pass costs $5 USD per day or $30 USD per year and is sold through Recreation.gov, forest service offices and many outdoor retailers in Washington State.
No overnight camping permit or quota system applies to dispersed camping within Olympic National Forest. Campfire regulations apply: check current fire restrictions before your trip, as the USFS frequently issues burn bans during dry August–September windows. Dogs are permitted throughout the trail on a leash.
Gear & Packing List
The Olympic Peninsula's wet climate and the river-crossing character of Trail #806 make gear selection more consequential than on a typical multi-day route. Prioritise waterproofing across every item category and build your kit around the assumption that something will get wet.
Backpack: For 2–3 days with full camping kit, a 40–65 litre pack is appropriate. The Hyperlite Mountain Gear 3400 Windrider (Dyneema Composite Fabric shell, inherently waterproof) is purpose-built for wet Pacific Northwest conditions and is a popular choice for the Olympic Peninsula. The Osprey Aether 65 suits hikers who prefer a more structured carry with a heavier overall loadout. Ultralight hikers comfortable with minimalist systems should consider the Zpacks Arc Haul Ultra 50L, which offers excellent capacity-to-weight ratio and a frameless design that packs down tight for river crossings.
Footwear: Low-cut trail runners are favoured by experienced river-ford hikers — they drain faster than boots and dry overnight at camp. Bring dedicated camp sandals to change into after crossings. Never ford in bare feet on the West Fork's rocky, slippery riverbed.
River crossing kit: Trekking poles are essential for balance and depth-probing on every ford. Unbuckle your pack's hip belt and sternum strap before each crossing. Pack all electronics, sleeping gear and food inside dry bags or a waterproof pack liner regardless of pack shell material.
Rain gear: A waterproof-breathable shell jacket is mandatory — condensation drip from old-growth forest canopy persists even on forecast-clear days in this valley. Budget 400–600 kcal per active hiking hour in this terrain; read the HikeLoad guide on how many calories you need for a full day of hiking to dial in your food weight accurately before departure.
Navigation: Cell service is absent through most of the valley. Download offline topographic maps before leaving the trailhead. Carry a printed backup map — the route is well-defined but trail junctions can be obscured by seasonal vegetation growth.
Water treatment: The West Fork Humptulips River is clear and cold but must be filtered or treated — giardia is documented throughout Olympic Peninsula backcountry water sources. A squeeze filter or UV pen adds minimal weight and is non-negotiable.

Frequently Asked Questions
What is the best time to hike the West Fork Humptulips Trail #806?
August is the single best month. River levels reach their annual low, making the multiple unmaintained fords safest for most hikers. Daytime valley temperatures run 18–24°C and the weather is at its driest. September is a strong second choice. Avoid October through June unless you have extensive high-water fording experience — river conditions can be life-threatening in that period.
How difficult is the West Fork Humptulips Trail #806?
Rated moderate-to-hard. Elevation gain is low — 213 metres over 27 kilometres — but the route crosses the West Fork Humptulips River multiple times with no footbridges. In summer low water, crossings run knee-to-thigh deep; in high water they are hazardous. Remote access and carrying a full multi-day pack justify the harder rating for less-experienced backpackers.
How far should I expect to hike per day on Trail #806?
Most backpackers split the 27 km over two days: 13 km to Pete's Creek camp on Day 1, 14 km to the upper trailhead on Day 2. Fit hikers can complete the full trail in one long day (7–9 hours moving time), but budget 20–30 minutes per river ford for a group to safely assess conditions and cross as a team.
Where do hikers camp on the West Fork Humptulips Trail #806?
Camping is dispersed and free throughout the national forest section. The primary overnight zone is the Pete's Creek confluence at kilometre 13, with flat ground and reliable water.
