Lewis and Clark Trail State Park is a 36-acre Washington state park on the Touchet River in southeastern Washington. Though small, it blends old-growth forest with 1,333 feet of river shoreline, creating both shaded woodland and waterside habitat. The park supports a wide range of uses, from quiet nature activities to everyday recreation. Visitors come for hiking, fishing, swimming, birdwatching, and wildlife viewing, and the park also offers camping, interpretive activities, and athletic fields. Its mix of mature forest and river access makes it a compact but diverse destination within Washington’s state park system.
