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.
Nature of the Area

History of the Area
The park was originally called "Miller's Glade" by the Miller family, who once owned the property. The family later changed the name to "Millersylvania," meaning "wooded glade." The park's 842 acres were homesteaded by Squire Lathum in 1855 before being sold to John Miller. Miller's family gave the property to the state in 1921, stipulating that the land must forever be used as a park.

Millersylvania's buildings were constructed in 1935 almost entirely by hand by the Civilian Conservation Corps. Relics of a narrow-gauge railroad, and several skid roads used in the 1800s by the logging industry, remain on park grounds. Stumps of trees still carry notch scars where springboards supported brawny loggers.
A Discover Pass is required for vehicle access to Washington state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.
