The 16,682-acre Brothers Wilderness lies within Olympic National Forest and occupies a blip of land on the eastern flank of Olympic National Park . Wilderness permits are not required in the Brothers Wilderness.
Only a few developed trails exist in the wilderness; the primary one is the Duckabush River Trail, which begins a mile up from the Collins Campground in Duckabush Recreation Area . The trail climbs six miles to the park boundary, with a view from Big Hump rock. Once inside the park, you can connect to a maze of other routes through the high country.
From Lena Lake Campground  on Hamma Hamma Road, a hiking trail leads uphill to Lena Lake on the edge of the wilderness, and then on to Upper Lena Lake inside Olympic National Park . This is a perfect overnight backcountry trip.
