Camp, Hike or Relax in Nature's Beauty in these beautiful state parks
Visit Washington's State Parks in Lewis County

Lewis County is home to several Washington State Parks that offer access to beautiful expanses of nature. Whether it's hiking along a peaceful stretch of the Chehalis River, camping in the middle of an old-growth forest or pedaling your bicycle from Chehalis to Pe Ell, several State Parks offer the opportunity for unlimited fun in the beauty of Lewis County's outdoors!

Three State Parks, two historic properties maintained by State Parks and a rail-to-trail that connect two of our towns make for some great outdoor recreation, and they are waiting for you, your family and your friends to visit!

If visiting by car, you'll want to get a Discover Pass, and you can get one online here. One-day passes are $10, but the best bang for the buck is found in the annual pass that cover 364 more days for just $20 more. However, if you're choosing to camp at a state park, no pass is required.

Also, in 2017, State Parks will waive day-use fees for 12 days next year at all state parks, offering a chance for you and yours to visit without the need for a Discover Pass. Fee-Free Days are perfect for people wanting to get a feel of what the State Parks are like, and offer a great opportunity to opt outside for an afternoon or so. Check our Events page for a list of Fee-Free Days!

PLEASE NOTE: Rainbow Falls State Parks is temporarily closed. We'll update you as to when it should reopen...we hope it's soon!

This park is a popular stopover and overnight camping spot for people traveling between the I-5 corridor and the coast. Rainbow Falls State Park offers 139 acres of recreation that includes 10 miles of hiking trails, 7 miles of biking trails and a giant meadow amid an old growth forest.

The park's main attraction is its namesake, the gentle Rainbow Falls on the Chehalis River. When the sun hits it just right, you can see a prism created by the water just above the falls.

Rainbow Falls State Park offers 53 campsites, with 39 of them being standard campsites. Eight are partial utility campsites made for RVs. Three are for horses and three are hiker/biker sites, perfect for people traversing the Willapa Hills Trail on two wheels, two feet or on a saddle. A group camp on site also accommodates up to 60 people.

Rainbow Falls is a non-reservation park, meaning you can drop in and get a campsite on a first-come, first-served basis. For more info on the park in general, visit State Park's website.


A former rail line that brought lumber, mail and passengers between Chehalis and the Pacific Coast has since become the Willapa Hills Trail, a corridor between Chehalis and South Bend in Pacific County that as of the beginning of 2017 fully connects Chehalis and Pe Ell. Cyclists, hikers, trail walkers and horseback riders have made the trail popular especially since last June, when the last gap between Chehalis and Pe Ell was bridged.

In Lewis County, the trail is a straight shot from Chehalis west to Adna, and from there the trail meanders along the Chehalis River and past adjoining forest and farmland before reaching Pe Ell. Several trailheads exist along the trail, some with horse trailer parking that provide easy equestrian access to the trail. The trail also passes near Rainbow Falls State Park, an ideal overnight spot.
