Lewis and Clark State Park preserves one of the largest tracts of lowland old-growth forest in Washington’s Lewis County. Much of the park’s infrastructure — including trails, picnic areas, and campgrounds — was constructed by the Civilian Conservation Corps in the 1930s, giving visitors a chance to experience both natural beauty and a piece of New Deal history.

The park features eight miles of hiking trails, including a beautifully maintained interpretive loop that winds through towering old growth stands, highlighting centuries-old Douglas firs, western hemlocks, and cedar groves. Horseback riders will find dedicated equestrian trails, and the campground is a favorite for family camping, with sites shaded by the forest canopy and easy access to trails, streams, and wildlife viewing.

Nearby, the park manages the John R. Jackson Courthouse, built in 1845 and recognized as the first permanent pioneer courthouse west of the Cascades and north of the Columbia River. While it’s no longer used as a courthouse, the historic structure offers a fascinating glimpse into early territorial life, and tours are available by appointment.
