Washington County

Lewis County, Washington

Mount St. Helens and Gifford Pinchot National Forest - from the Mount St. Helens National Volcanic Monument (the southern portion of Lewis County provides access to the volcano that dramatically erupted in 1980, and the Gifford Pinchot National Forest surrounding it covers much of the county's eastern terrain with old-growth forests, volcanic landscapes, and the stunning Johnston Ridge Observatory overlooking the crater) to the Cowlitz River corridor (the Cowlitz River drains Lewis County's mountain terrain through a valley of dairy farms, small towns, and timber operations that represent classic western Washington rural character between Portland and Seattle along I-5).
