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. Discover Pass: A Discover Pass is required for vehicle access to state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.


Chehalis River

The Chehalis River begins at the confluence of the West Fork Chehalis River and East Fork Chehalis River, in southwestern Lewis County. From there the Chehalis flows north and east, collecting tributary streams that drain theWillapa Hills and other low mountains of southwestern Washington. The South Fork Chehalis River joins the main river a few miles west of the city of Chehalis. The Newaukum River joins the Chehalis River at Chehalis, after which the river turns north, flowing by the city of Centralia, where the Skookumchuck Riverjoins. After Centralia, the Chehalis River flows north and west, collecting tributaries such as the Black River, which drains the Black Hills to the north, then in the Chehalis Gap collects the Satsop River and Wynoochee River, which drain the southern part of the Olympic Mountains.

The Wynoochee River joins the Chehalis near Montesano, after which the Chehalis River becomes increasingly affected by tides and widens into Grays Harbor estuary. The city of Aberdeen lies at the mouth of the Chehalis River. Just east of Aberdeen, the Wishkah River joins the Chehalis, and just west, between Aberdeen and Hoquiam, the Hoquiam River joins. At this point the river has become Grays Harbor. Before the estuary of Grays Harbor empties into the Pacific Ocean, the Humptulips River joins.
