Snohomish National Forest was a former national forest in Washington known for its rugged mountainous terrain, dense coniferous forests, and abundant outdoor recreation opportunities within the western Cascades. Although it was merged into Mount Baker-Snoqualmie National Forest, its legacy remains important for hikers, campers, and nature enthusiasts.
Snohomish National Forest was established in 1908 in the western Cascade Range of Washington State and later merged with Mount Baker National Forest in 1974 to form Mount Baker-Snoqualmie National Forest. Occupying an area rich in steep ridges, deep valleys, and glacier-carved alpine landscapes, it supported a diverse mix of ecosystems from lowland temperate rainforests to subalpine and alpine zones. The forest was dominated by towering Douglas firs, western hemlocks, and western red cedars, and it served as habitat for species such as black bears, Roosevelt elk, northern spotted owls, and salmon in its rivers and streams. The area attracted outdoor enthusiasts with its extensive trail network, waterfalls, scenic vistas, and access to high mountain peaks like Glacier Peak. Popular activities included hiking, backpacking, fishing, climbing, and winter sports. Iconic landmarks in the former Snohomish National Forest area included the Mountain Loop Highway, a scenic byway providing access to backcountry trails and campgrounds, and areas like the Wallace Falls and Monte Cristo mining ghost town. The forest's history reflects early 20th-century conservation efforts intertwined with logging and mining legacies, balanced today with preservation and sustainable recreation management. Though no longer designated independently, the lands once known as Snohomish National Forest remain a key part of Washington's natural heritage, offering varied terrain and year-round adventure opportunities.
