As Bellevue and surrounding areas become more densely populated, the natural character of the region’s wetlands becomes more difficult to preserve. The Mercer Slough Nature Park is a unique, 320-acre wetlands preserve in the heart of the city.

Skyscrapers form a backdrop to the Slough’s waterways, marshes, meadows and woodlands. The park can be explored on foot via the trail system or on the many waterways by kayak or canoe.

As an outdoor laboratory, the Mercer Slough is the largest remaining wetland contiguous to Lake Washington, as well as one of the most diverse ecosystems in the region. It offers a striking opportunity for interactive science and environmental learning. The current Mercer Slough Environmental Education Center, located within the park since 1993, capitalizes on this unique opportunity to engage participants in experiential education focusing on environmental stewardship, wetland ecology and nature awareness.
