- Lewis and Clark Trail State Park covers 37 acres with 1,333 feet of freshwater shoreline on the Touchet River. The park offers 30 standard campsites, 50 picnic sites, a large kitchen shelter, one small kitchen shelter, a trailer dump, a group camp site with a 50-person capacity, a 1.0 mile interpretive trail, one small interpretive display shelter, a .75 mile bird watching trail, a small shop, and an amphitheater for campfire programs.
Recreation - Activities at the park include bird watching, camping, fishing, hiking, picnicking, sledding and base camping for big game and bird hunting.
Climate - Washington's climate varies with each region. The Cascades split the state and alter weather patterns. Lewis and Clark Trail State Park, located east of the mountains, receives significantly less rainfall than regions west of the mountains with an average annual precipitation of twelve inches.
Average summer temperatures are 94 degrees maximum and 50 degrees minimum. Because central Washington is landlocked and subject to winter winds, winter temperatures are much colder than those in western Washington.
Lewis and Clark Trail State Park, in southeast Washington, is located in
Columbia County, on U.S. 12 between Waitsburg and Dayton.
