Located on the eastern shore of Lake Goodwin, this award-winning park offers splendid opportunities for picnicking, sunbathing, boating, and camping. Within these 45 acres, you'll discover a 70-site campground, three picnic shelters, an enclosed swim beach with rinse shower, and 1,140 feet of freshwater shoreline with a two-lane concrete boat launch for your toys. The day-use area restroom is closed and winterized November-March.

Management of the park was transferred to Snohomish County from the Washington State Parks and Recreation Commission on July 16, 2009, in an effort to keep state parks open and available to residents and visitors while responding to state budget reductions. In 2018, the day-use area was renovated to provide much-improved ADA access to the swimming beach and swimming/fishing dock.
