Lewis and Clark State Park: Historic Old-Growth Forest Sanctuary with Equestrian Trails

Lewis and Clark State Park preserves one of the last major stands of lowland old-growth forest in Washington state, offering visitors a rare opportunity to experience ancient Douglas fir and Western Red Cedar trees in a 616-acre camping park near Winlock. Established in 1922 as a “public camp” for automobile tourists, this historic park features rustic Civilian Conservation Corps buildings and welcomes both equestrians and hikers to explore 8 miles of trails through pristine forest corridors, wetlands, and along creek systems that showcase the Pacific Northwest’s original forest ecosystem.

Park Overview

Lewis and Clark State Park occupies one of Washington’s most significant old-growth forest preserves, representing the largest tract of ancient forest contained within the state park system when it was established. Located six miles northeast of Winlock, the park began as a 520 acre preserve announced by the state park board in May 1922, with Governor Louis F. Hart dedicating the grounds on September 23, 1922. The park operates under a 1921 legislative resolution requiring it to remain as a natural wooded area, ensuring permanent protection of this irreplaceable ecosystem.

The park’s ancient forest faced significant challenges during the Columbus Day Storm of 1962, which destroyed two-thirds of the old-growth trees, reducing the forest from 13.5 million board feet to just 5 million. However, recovery areas now demonstrate forest regeneration, while remaining old growth sections continue to provide visitors with authentic experiences among massive Douglas Fir and Western Red Cedar specimens. Lewis and Clark State Park serves as both a natural sanctuary and historical preservation site, maintaining Civilian Conservation Corps structures built during the 1930s that exemplify rustic park architecture.

Gear Up for Washington Weather

Washington trails are wet more often than not, and the right gear makes the difference between a great day out and a miserable one. We recommend KEEN Targhee IV Waterproof Hiking Boots for solid traction on muddy and rocky terrain, a North Face Alta Vista Rain Jacket because you will need it even on days that start sunny, and the REI Co-op Flash 22 Pack to carry your layers, water, and snacks. All three are available in men's and women's versions. (affiliate links)
