Millersylvania State Park offers fun for everyone. Spend a summer day splashing in Deep Lake. Gather with friends in an historic kitchen shelter. 

Conveniently located between Olympia and Centralia, this large, well-visited park beckons to adults and children alike.

Many of the park structures, including the kitchen shelters, were built by the Civilian Conservation Corps (CCC) in the 1930s, making the park a great place to see and admire the hallmark artisanship of that era.

With two swimming beaches, miles of forested hiking and biking trails, watercraft launches, non-motorized watercraft rentals (kayaks, paddleboards, pedal boats) and abundant fishing, Millersylvania will keep you busy for a satisfying weekend or an extended outdoor vacation.
