Just minutes from downtown, the Mercer Slough Nature Park is the largest of Lake Washington’s remaining fresh water wetlands and Bellevue’s largest park. Explore over 320 acres of wildlife habitat, agriculture, and freshwater wetland ecosystems on 7+ miles of trails including a unique canoe trail. The blueberry farm sells fresh seasonal produce. The beautifully restored historic Winters House is Bellevue’s only public building on the National Historic Register. It serves as the home of the Eastside Heritage Center, the park visitor’s center, and is available for meeting and event rentals. The Mercer Slough Environmental Education Center is a partnership with the Pacific Science Center focusing on freshwater wetland ecology.
