Parking
No road-access trailhead serves LaCrosse Pass. Reach its north end from the West Fork Dosewallips River Trail or its south end from the Duckabush River Trail; both require a backcountry approach.

LaCrosse Pass Trail is a 6.4-mile, one-way backcountry connector between the West Fork Dosewallips River Trail junction and the Duckabush River Trail junction. It climbs to the 5,566-foot pass, then descends into the Duckabush valley; this is a point-to-point segment, not a loop. It is usually part of a longer wilderness itinerary, not a hike from a road. Allow around five to six hours for this segment alone; that is a planning estimate for its distance, roughly 2,000 feet of climbing and steep mountain tread.
The north side rises more gradually through montane and subalpine forest before opening into high-country meadows. The tread is maintained, but the climb is still substantial. Snow can obscure the upper route in any season, so map-and-compass skills may be needed when the tread disappears.
The open meadow and surrounding ridgelines are the main payoff at LaCrosse Pass. From there, the southern side drops steeply to the Duckabush River Trail junction. There is no water near the pass: carry enough for the crossing and treat water collected from lower streams or rivers. The route finishes well below its start, so plan for a long descent after the climb.
There is no road-access trailhead at LaCrosse Pass. Reach either end on foot from other trails, and plan your approach, exit and overnight itinerary before setting out. There are no established campsites or toilets on this named segment. Overnight wilderness camping requires a permit, and pets are not allowed in park wilderness. Mid-July through October is the usual season, though snow can linger on the high trail.
