Mercer Slough Nature Park protects a substantial wetland landscape within Bellevue.

Trails, boardwalks, and interpretive programs connect visitors with the water, plants, and wildlife of the slough. The photograph shows a teaching space at the Environmental Education Center, one part of the wider park experience.
Choose a specific trailhead or program location before traveling, since the park has several access points. Check current route notices and reserve guided activities separately when required. Stay on established paths around wetland habitat, bring suitable footwear after rain, and give wildlife space.
