Millersylvania State Park

Millersylvania State Park spans 903 acres of land with old-growth cedar and fir trees along 3,300 feet of Deep Lake shoreline in Washington state.

The Miller family homesteaded this land in the 1800s and donated the property to Washington state in 1921 for establishment as a public park.

The Civilian Conservation Corps constructed numerous buildings, trails, roads, and facilities in the park during the 1930s, which remain functional today.

The park requires a Discover Pass for entry and provides camping areas, swimming beaches, hiking trails, boat launches, and picnic facilities throughout the grounds.

The park contains remnants of 19th-century logging operations, including tree stumps marked with springboard scars from early timber harvesting methods.
