Nestled in the heart of Bellevue, the 320-acre Mercer Slough Nature Park offers a tranquil setting for a variety of recreational experiences: biking, hiking, canoeing , blueberry picking, and environmental education. The Mercer Slough is Lake Washington’s largest remaining wetland, containing hundreds of plant species and an abundance of water resources. The park provides a diverse habitat for over 170 species of wildlife. Interconnected boardwalks, soft surface trails, and asphalt paths transport visitors through this unique urban wetland.
