Mercer Slough's Environmental Education Center is a collaboration between the City of Bellevue and Pacific Science Center. The MSEEC is comprised of a visitor center, classrooms, a community building, a “tree house”, and an elevated boardwalk. The center offers various ranger programs such as nature walks and, art in nature classes. The visitor center features interpretive displays about the park’s history as well as a library with books, field guides and park information. The boardwalk area provides a lookout across the slough and a bird’s-eye view of the city skyline. Groups may rent the 1,575-square-foot Douglas Fir Community Room which is a fun location to hold meetings, retreats, classes, and small social gatherings.
