Opal Creek Wilderness and Scenic Recreation Area Area Trails Professional Review and Guide
"Opal creek is one of the most beautiful streams in western Oregon. It flows into the Little North Fork of the Santiam River. A limpid blue color, the creek pours over water-rounded boulders and among lichen-shrouded, old-growth Douglas fir forests. The wilderness and scenic area protecting the Opal Creek drainage was created in 1996 and established in 1998. It lies immediately east of the Bull of the Woods Wilderness and includes about 8,000 acres of lands formerly part of that wilderness. Elkhorn Creek, a major tributary here of the Little North Santiam, was also designated a Wild and Scenic River.
Both Elkhorn Creek and the Little North Santiam River support steelhead runs. Opal Creek Wilderness boasts steep, rugged, forested hillsides. The eastern portion of the area encompasses the headwaters of two major creeks, Battle Ax and Opal, which join and flow into Little North Santiam River. The western portion of the area is dominated by two prominent peaks, Whetstone and Henline Mountains, both former fire lookout sites. This trail guide contains three trails ranging from 3.5 to 14.5 miles in length."
