Lake Sylvia State Park is a quiet, 233-acre camping park with 15,000 feet of freshwater shoreline. The park is an old logging camp in a wooded area halfway between Olympia and the Pacific shore. Aside from the interesting displays of old logging gear and curiosities, the lake is good for fishing, and the rustic charm of the park makes for excellent day outings and group camping trips.

Huge, old-growth stumps are everywhere in the park. There is a giant wooden ball carved from a single log by a local logging legend. Story has it the logger could stand atop the floating ball and "walk it" from one end of the lake to the other. The area is rich with logging lore and history. When logging ceased in 1930, the dam was used to generate electricity for the town of Montesano. In 1936, Montesano donated the land to the State Parks Commission for conservation. Addditional lands were added by a trade in 1985.
