Tall Douglas firs and old-growth cedar close in quickly once you leave the highway, giving Lewis & Clark State Park Campground a forested density that reviewers consistently notice. The campground sits off Jackson Highway near Winlock, Washington, and is managed by Washington State Parks. Note that Google Maps sometimes routes visitors to the wrong entrance: the correct entry is on Jackson Highway, not Park Road. The park runs from May through September and accepts both reservations and first-come, first-served campers, with sites ranging from tent-only spots to full hookups with electric, water, and sewer connections.
The layout divides into two distinct areas. Sites to the west sit deeper into the forest, with large, well-spaced lots and access to hiking trails that wind through old-growth stands. The full-hookup RV sites on the east side of the road sit close to a paved highway used by logging trucks, and multiple reviewers flag road noise and proximity to traffic as real drawbacks for that section. Campers in tents or smaller rigs who land a forested site tend to report a noticeably different experience. The park also has equestrian trails, covered outdoor kitchen areas for day use, and an amphitheater. Showers and flush toilets are available, though only two bathrooms serve the entire campground.
One past reviewer noted an E. coli water advisory posted on spigots during their stay, a reminder to check current water quality before arrival. "Immaculately maintained," writes Ray B. of the forested side. Campers using this as a base for Mount St. Helens or Mount Rainier day trips will find it a functional overnight stop, and those who secure a west-side site among the old-growth trees get considerably more than that. Nearby alternatives include Cowlitz River Blue Creek Boat Ramp to the southeast and Kemp Olson Memorial Park to the south for those weighing campgrounds near Toledo.
Description
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.
