Lewis and Clark State Park (SW Washington)
October 2026
About
Lewis and Clark State Park is a 616-acre camping park in a stand of old-growth forest. This cool forested space east of I-5 and south of Chehalis offers hiking and horseback riding through a rare stand of old-growth trees on the historic north spur of the Oregon Trail. The park provides an all-American camping experience, with fire circles, an amphitheater and horseshoe pits.
Is Lewis and Clark State Park (SW Washington) fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
