Knappton Hollow Natural Area is a protected forested region along the Columbia River Gorge known for its old-growth forests, diverse wildlife habitat, and quiet hiking trails.
Knappton Hollow Natural Area is located on the Washington side of the Columbia River Gorge, approximately 10 miles east of Astoria, Oregon. The area covers steep slopes and ravines dominated by mixed old-growth and second-growth forests primarily composed of Douglas-fir, western hemlock, and red cedar. This natural area features dense understory vegetation including salal, tanoak, and sword fern, supporting a rich biodiversity including black-tailed deer, Roosevelt elk, and numerous bird species such as pileated woodpeckers and northern spotted owls. Historically, the area was part of Native American fishing and hunting grounds before logging activities diminished old-growth stands in the 19th and early 20th centuries. Today, conservation efforts focus on protecting remaining old-growth patches and restoring habitat connectivity. Visitors appreciate the serene environment for hiking and wildlife viewing along several modest trails that wind through the hollow and offer views into the Columbia River Gorge. The area also provides valuable riparian habitat important for local fish species and supports a range of mosses and lichens uncommon in more developed forest areas nearby. Despite its modest size compared to larger regional parks, Knappton Hollow offers an escape into quiet forest scenery and serves as a vital refuge for sensitive species, making it an appealing destination for nature enthusiasts and birdwatchers.
