Lake Sylvia State Park

Montesano, WA 98563


Adults, kids and adult kids, go play at Lake Sylvia State Park!

Hidden in the hills between Olympia and the Washington Coast, Lake Sylvia is a classic state park. Set in a former logging camp above the historic town of Montesano, park life revolves around a large swimming and fishing lake that draws families to its shores all summer long.

While children head straight for the water or the playground, grown-ups and teens take advantage of the old logging roads-turned-bike-trails. You may end up muddy, tired and happy after a day of riding.

Hikers come from all around southwest Washington to cover the year-round, 5-mile loop trail, which rolls gently from the campground, over wetlands and a small covered bridge. A walk around the lake reveals a dam that provided hydro-electric power to the logging camp in the early 1900s. Park trails connect to a network of hiking and biking trails in the surrounding 5,000-acre Montesano City Forest.

The kids won't want to get out of the water on a warm summer day, so why not make it a campout at this charming family park?

Lake Sylvia State Park is a wooded, 252-acre camping park with 15,000 feet of freshwater shoreline. Aside from displays of 20th-century logging gear, the lake offers abundant fishing, and the rustic charm of the park makes for excellent day and group camping trips.
