LaCrosse Pass Trail

The LaCrosse Pass Trail is a 10-km point-to-point trail in Olympic National Park, Washington, USA, gaining roughly 600 m of elevation to LaCrosse Pass at 1,696 m above sea level. Rated moderate-to-strenuous, this remote alpine route connects the Duckabush River valley to the West Fork Dosewallips Trail through old-growth temperate rainforest, steep switchbacks, and sweeping subalpine meadows with panoramic views of Mount Anderson and the Olympic glaciers.

About the LaCrosse Pass Trail

Tucked deep in the eastern interior of Olympic National Park, the LaCrosse Pass Trail is one of the least-visited yet most rewarding mountain routes in Washington State. The trail spans 10 km end to end, threading through three distinct ecosystems — dense old-growth temperate rainforest, montane conifer forest, and high subalpine meadow — before cresting LaCrosse Pass at 1,696 m (5,566 ft). From that summit, the trail drops sharply into the West Fork Dosewallips drainage, making it a natural connector for multi-day backcountry loops in the Olympic interior.

The route is classified as part of the Regional Walking Network (RWN), designating it a significant connector trail within the broader Olympic wilderness system. Hikers completing the full point-to-point traverse link two of the park's major river drainages — Duckabush and Dosewallips — in a single crossing, which is why LaCrosse Pass regularly appears as a key segment in 4–6 day backcountry loops that extend to Anderson Pass, O'Neil Pass, and the Enchanted Valley.

Administered by the U.S. National Park Service, the LaCrosse Pass Trail demands solid navigation skills. At higher elevations, the path can be obscured by snow well into July, and no established campsites exist along the route itself — hikers camp on bare ground at least 60 m (200 ft) from water sources, consistent with Leave No Trace principles enforced throughout the Olympic backcountry. Bear canisters are mandatory for all food storage.

The pass itself offers a moment of genuine wilderness solitude that is increasingly rare in the Pacific Northwest. Views stretch north toward Mount LaCrosse and east to the ice-capped dome of Mount Anderson at 2,362 m — one of the most glaciated peaks in the Olympic Range. On a clear day the panorama spans ridge after ridge without a road or building in sight. The western descent reveals lake basins, talus fields, and the deep green of the Dosewallips valley far below.

Planning a multi-day loop using LaCrosse Pass as one leg means carrying several nights of gear over steep terrain. Packing light pays real dividends here.

Route Overview & Stages

The LaCrosse Pass Trail runs 10 km point-to-point, ascending approximately 600 m from the Duckabush River valley floor to the pass at 1,696 m, then descending steeply — around 610 m — to the West Fork Dosewallips River junction. The trail is strongly directional. Most hikers begin on the Duckabush side and exit via Dosewallips, though the route is hikeable in either direction depending on shuttle logistics or loop design.

Water is reliable from the Duckabush River and seasonal streams through Stage 2. Carry at least 2 litres per person above the tree line — sources near the pass dry up by late summer and at all lower elevations water must be treated before drinking. No water is available near the summit itself.

Highlights & Points of Interest

• LaCrosse Pass (1,696 m / 5,566 ft) — The high point of the route and its defining reward. The pass delivers unobstructed 360-degree views of the Olympic interior: Mount LaCrosse to the north, Mount Anderson and its glacier to the east, and a sea of forested ridges in every other direction.
• Duckabush River Valley — The lower trail follows the Duckabush corridor through one of the finest old-growth forests in Olympic National Park. Western red cedar, Douglas fir, and vine maple create a cathedral canopy, and the river runs vivid glacial green in early season.
• Subalpine Meadows near the Pass — The upper 2 km open into broad meadows carpeted with heather, Cascade huckleberry, and mountain lupine. In late July and August the wildflower display rivals any in the Olympic Range — paintbrush, bistort, and valerian colour the slopes on either side of the trail.
• Mount Anderson Glacier Views — From both the pass and the upper descent, Mount Anderson's retreating glacier is clearly visible to the northeast. The glacier has contracted significantly since the 1980s, and hikers today see a fraction of the ice that covered these slopes in historical photographs — a stark reminder of climate change in real time.
• Lake LaCrosse Basin — Just below the pass on the western descent, the Lake LaCrosse basin opens below the trail. The glacially carved tarn sits at approximately 1,550 m and reflects the surrounding ridgelines on calm mornings. A rough use trail drops into the basin from the main route.
• Old-Growth Temperate Rainforest — The lower stages pass through forest groves where individual trees exceed 400 years of age. The dense canopy and heavy moss coverage — on trees, rocks, and fallen logs — are characteristic of the wet eastern drainages of Olympic and feel unlike any forest in the contiguous United States.
• West Fork Dosewallips River Junction — The trail's lower terminus connects to the West Fork Dosewallips Trail, the gateway to Anderson Pass, Honeymoon Meadows, and the broader Dosewallips backcountry system. For multi-day hikers, this junction is a genuine crossroads of the Olympic wilderness.
• Wildlife Corridors — The LaCrosse drainage is active habitat for black bear, Roosevelt elk, and Olympic marmot. Early morning hikers frequently encounter elk on the upper meadows in August and September. Bear activity is consistent in the huckleberry zones below the pass from late summer onward.

Best Time to Hike the LaCrosse Pass Trail

The LaCrosse Pass Trail is reliably accessible from mid-July through early October in most years. Snow persists on the upper switchbacks and meadow sections through late June and can return by mid-October with early autumn storms. As of 2026, the seasonal window remains consistent with historical patterns, though year-to-year variability of 2–4 weeks is normal. Check current trail conditions with the Washington Trails Association before departure — their trip reports are updated by hikers within days of trail conditions changing.

Best month: August. Days reach 15+ hours of daylight at this latitude, afternoon thunderstorms are less frequent than in July, and the wildflower display on the upper meadows peaks between late July and mid-August. Temperatures at the pass typically range from 5 °C at night to 18 °C by midday — cool enough for energetic hiking, warm enough for comfortable breaks at the summit.

July carries snow risk on the upper trail; postholing above 1,400 m is possible before the third week of the month. The Duckabush River also runs highest in early July from snowmelt, and crossings require extra care. September is an excellent alternative — crowds drop dramatically after Labor Day, huckleberries ripen on the upper slopes, and the air takes on the crisp clarity of early autumn. Nighttime temperatures near the pass fall close to 0 °C by late September, so carry adequate insulation. October hikes are possible in dry years but require experience with early snow and a firm commitment to turning back if conditions deteriorate above the switchbacks.

Practical Information

Accommodation

There are no established campsites on the LaCrosse Pass Trail itself. Backcountry camping is permitted on bare ground at least 60 m (200 ft) from any water source, trail, or other camping group. Common stopping points include the Duckabush River flats in the lower valley and sheltered hollows just below the pass on the western side, where the terrain flattens briefly before the main descent.

Wilderness permits are required for all overnight stays in Olympic National Park's backcountry. The permit fee is approximately $8 per person per night (roughly €7.40 at 2026 exchange rates), plus a non-refundable reservation fee of $6 (approximately €5.50) per trip. Permits can be reserved in advance through Recreation.gov or obtained on a walk-up basis from the Dosewallips or Quilcene ranger stations when availability remains.

The nearest indoor accommodation is in the Brinnon area, approximately 20 km from the Duckabush trailhead on US-101. Budget motels start around $90/night (approx. €83). Hood Canal vacation rentals and cabins range from $120–$200/night (€110–€185) and fill quickly during peak summer weekends.

Getting There & Back

The Duckabush River trailhead sits on the eastern edge of Olympic National Park. From US Highway 101, turn west just north of Brinnon, Washington, onto the Duckabush River Road and follow it approximately 14 km to the trailhead parking area. A 4WD vehicle is not required, but high clearance is useful after heavy rain. The road is unpaved for the final section.

From Seattle-Tacoma International Airport (SEA), the drive to the trailhead takes approximately 2.5–3 hours (220 km via I-5, WA-16, WA-3, and US-101 North). There is no public transport to the trailhead — a rental car is essential for all visitors arriving by air.

For the full point-to-point traverse, a vehicle shuttle or pre-arranged pickup at the West Fork Dosewallips trailhead is required. The two trailheads are approximately 55 km apart by road, which takes around 1 hour to drive. Many hikers avoid the logistics entirely by incorporating LaCrosse Pass into a multi-day backcountry loop that returns to the Duckabush trailhead.

Permits & Fees

Olympic National Park charges a vehicle entrance fee of $30, valid for 7 days (approximately €27.70). The America the Beautiful Annual Pass at $80 (€74) covers entry at all U.S. federal lands and is cost-effective for hikers visiting multiple national parks in a season.

Overnight backcountry trips require a Wilderness Permit ($8/person/night + $6 reservation fee). Bear canisters are mandatory for all food storage in the Olympic backcountry — rangers conduct canister checks at major trailheads during peak season. Campfires are prohibited above 1,067 m (3,500 ft), which includes all terrain near LaCrosse Pass. All human waste must be buried 15–20 cm deep at least 60 m from any water source, and all toilet paper must be packed out.

Gear & Packing List

The LaCrosse Pass Trail's steep terrain, remote location, and rapidly changing Olympic weather demand gear chosen for reliability and weight discipline. The 600 m elevation gain on rugged switchbacks — combined with the steep descent into Dosewallips — rewards those who have trimmed their pack weight without sacrificing the essentials.

Backpack: For a single overnight on this trail, the Hyperlite Mountain Gear Aero 28 is a well-matched choice — Dyneema composite fabric handles Olympic rain efficiently and 28 L carries a lean overnight kit without excess. For a 2–3 night loop incorporating Anderson Pass, the Hyperlite Mountain Gear 2400 Windrider offers the same ultralight durability at a slightly reduced volume. Hikers carrying a full multi-day kit for 4–5 nights should consider the Zpacks Arc Haul Ultra 50L, which balances generous capacity with a carry weight that stays below the pain threshold on steep ascents.

Footwear: Waterproof trail runners or light hiking boots with ankle support. The Duckabush River crossing in early season runs cold and fast — footwear you can safely get wet is more useful than waterproof boots that soak through anyway.

Layers: Olympic Mountain weather moves fast. Even in August, carry a waterproof shell, a mid-layer fleece, and a lightweight insulation piece. Temperature at the pass can drop 8–10 °C within an hour when a Pacific front pushes inland.

Navigation: A downloaded offline map (CalTopo or Gaia GPS) plus a paper USGS 7.5-minute topo for the Mount Steel and The Brothers quadrangles. Snow can obscure the trail above 1,400 m into late July, and map-and-compass skills are expected in the Olympic backcountry.

Bear canister: Mandatory throughout the Olympic backcountry. The BV500 and BearVault BV450 are both NPS-approved and sized appropriately for 3–5 days of food.

Food and hydration: Plan 500–700 kcal per hour of moving time at this elevation gain rate. Read How Many Calories Do You Need Hiking a Full Day? for a practical framework for calorie planning before you pack your food bag.

Frequently Asked Questions

What is the best time to hike the LaCrosse Pass Trail?
August is the single best month. Snow has reliably cleared from the upper trail by early August, the wildflower display on the subalpine meadows peaks between late July and mid-August, and days are long. The trail is generally accessible from mid-July through early October. Avoid June — snow above 1,400 m is unreliable until mid-July, and the Duckabush River crossings run dangerously high from snowmelt. Always check current conditions before setting out.

How difficult is the LaCrosse Pass Trail?
The trail is rated moderate-to-strenuous. The 600 m of elevation gain from the Duckabush valley to the pass is concentrated in Stages 2 and 3, where the path switchbacks steeply up the valley wall with little respite. The descent to West Fork Dosewallips loses approximately 610 m over 3 km — hard on the knees without trekking poles. Navigation skills and comfort with off-trail snow travel in early season are expected. Fit hikers with backcountry experience will manage it confidently.

How far is it per day and how long does the hike take?
The full 10 km point-to-point takes most hikers 5–7 hours of moving time depending on pace and rest stops. It is manageable as a strenuous day hike with a vehicle shuttle between the two trailheads. More commonly, hikers incorporate LaCrosse Pass into a 2–4 night backcountry loop through the Duckabush, Dosewallips, or Quinault drainages, typically covering 10–15 km per day on adjacent trails.

Are there huts or established campsites on the trail?
No huts or established campsites exist on the LaCrosse Pass Trail itself. Backcountry camping is permitted on bare ground at least 60 m from water, trails, and other camping groups. A Wilderness Permit ($8 per person per night) is required for all overnight stays. Campfires are prohibited above 1,067 m. Carry a freestanding tent — there are no shelters anywhere on this route, and exposure near the pass in a storm is a genuine risk.

Do I need a permit to hike the LaCrosse Pass Trail?
Day hikers need only the park entrance fee — $30 per vehicle for 7 days, or $80 for the annual America the Beautiful pass. Overnight trips require a Wilderness Permit ($8 per person per night plus a $6 non-refundable reservation fee per trip). Bear canisters are mandatory for all food storage. Permits can be reserved at Recreation.gov or obtained walk-up from the Dosewallips or Quilcene ranger stations subject to availability.
