A designated swimming area and playground are the perfect spots for kids to let off some steam.

But summer isn’t the only time that visiting this park is a must. In the surrounding forests, a network of hiking and biking trails provide an excellent way to discover the park’s natural beauty, astonishing birdlife and wildlife.

Formerly known as Mayfield Lake State Park, the park was renamed in 1971 to honor the Cowlitz Indians who once lived here and whose burial grounds can be found nearby. Today, the campgrounds are forested and offer all the conveniences you need for you next RV getaway.
