Constance Pass Trail

Constance Pass Trail is a remote 10.7-mile, one-way route from the Dosewallips Campground walk-in trailhead to the Olympic National Park boundary. It follows the Dosewallips River Trail, climbs through Sunnybrook Meadows and over Constance Pass, then reaches Home Lake. The trail is difficult; allow about 10 hours for the route itself. It is a point-to-point crossing, so arrange an exit at the far end before setting out.

The route starts along the Dosewallips River before climbing through montane forest on a steep series of switchbacks. Sunnybrook Meadows opens into subalpine country, but the tread gets rougher above it. Some rockslide sections are eroding and hard to follow, so this is a poor place to rely on a casual stroll or a phone signal.

The trail reaches the high pass, then continues toward Home Lake and the park boundary. At the boundary it carries on into the Buckhorn Wilderness as the Home Lake Trail. That extension is part of the through-route here; it does not loop back to the Dosewallips start. The lake and jagged peaks make a strong high-country payoff after the long climb.

Water is scarce on the upper route: the park reports no source until about half a mile below Sunnybrook Meadows, and stream water needs treatment. Snow can cover the high sections in any season, and map-and-compass navigation may be necessary. There are no toilets on the route. Overnight stays need a wilderness permit, bear canisters are required where food cannot be hung safely, and pets are not allowed on the trail.
