About Willapa Hills State Forest

 

Willapa Hills State Forest covers roughly 160,000 acres in southwestern Washington, spanning parts of Pacific, Lewis, and Wahkiakum counties. The forest features dense stands of Douglas fir, western hemlock, and cedar interspersed with alder and maple, thriving in the wet, mild climate characteristic of the region. The terrain includes rolling hills, riparian corridors with clear streams and small rivers, and pockets of old-growth forest. Historically, the area supported Native American communities and later commercial timber harvests, with modern conservation and active forest management balancing recreation and resource use. Outdoor enthusiasts find abundant trails for hiking, mountain biking, off-road vehicle riding, and horseback riding, spread across several trail systems including the Willapa Hills Trail, a 56-mile multiuse trail converted from a former railroad line. The forest supports rich wildlife including Roosevelt elk, black-tailed deer, black bears, and numerous bird species. Visitors are drawn by the forest’s remote character, accessible trailheads, and seasonal wildflowers and mushrooms. Fishing and hunting are also common, regulated by state rules. The forest does not have formal national park status but serves as a critical ecological and recreational resource in Washington’s coastal zone, offering a quieter alternative to more developed parks.
