The Mercer Slough Nature Park can be entered from the Winters House, Mercer Slough Blueberry Farm, Sweyolocken Boat Launch, Ballefield Trailhead and Mercer Slough Environmental Education Center. Just minutes from downtown Bellevue, it is the largest of Lake Washington's remaining fresh water wetlands and is one of Bellevue's largest parks.
There are over seven miles of trails throughout the park, waterfront access, canoe launch and picnic areas. The blueberry farm sells fresh seasonal produce and the Winders House is Bellevue's only public building on the National Historic Register.
