The Duckabush River Trail provides access to the Olympic National Park via a 6.7 mile hike over Big Hump and through The Brothers Wilderness. The trail is terrific for backpacking, hiking, fishing, wildlife viewing, and enjoying the scenery. There are several campsites on the Forest Service portion of the trail, before the National Park Service boundary is reached. These campsites lie in the lower Duckabush Valley.

Once crossing the Park boundary, the trail continues for another 15 miles, eventually ending at O'Neil Pass. It passes through camps at Ten-Mile (10.6), Upper Duckabush (17.7) and Marmot Lake (20.1).

The Park portion of the trail receives moderate use and maintenance normally does not occur until late in the summer. The river ford at Upper Duckabush can be hazardous to cross in spring and early summer. The grade steepens as you climb into the subalpine headwaters at Marmot Lake and then on to O'Neil Pass. Upper Duckabush and Marmot/Hart Lakes are primary late summer destinations due to late melt out of snow. There are stock camps at Ten-mile and Upper Duckabush.

Directions: From Hoodsport, Travel north on Highway 101 for approximately 22 miles to the Duckabush Recreation Area. Turn onto the Duckabush River Road, FS Road #2510. Drive 6 miles. The trailhead lies about 3/4 miles beyond the entrance to Collins Campground
