Map & visitor guide

Lewis & Clark Trail State Park is a 36-acre camping park with 1,333 feet of freshwater shoreline on the Touchet River. Located along Highway 12, amid the rolling fields of southeastern Washington, it feels like a lush oasis in an otherwise dry landscape. Shaded trails through pondersa pine, alder, maple and cottonwood trees offer river access for tubing and wading. Birdwatchers may see common mergansers, red-tailed hawks and orange-crowned warblers, among others. 

Picnic and day use facilities 

A reservable kitchen shelter with electricity is available. To reserve, call the park office at (509) 337-6457.


Standard, non-hookup campsites can accommodate tents or motorhomes. Teepees and group camps are also available.
