Mercer Slough Environmental Education Center

Would you like to be a Master Naturalist?

Bellevue Master Naturalists learn about our area’s ecology, geology, wildlife, plant life, cultural history, wetlands, forests, and streams from professors, local professionals, scientists, research assistants, and Park Rangers. Master Naturalists will focus on restoration and conservation efforts, and will help share this passion by working with and educating their community.

MSEEC Boardwalk

The Mercer Slough Environmental Education Center provides a grand entrance to the Mercer Slough Nature Park. Completed in October 2008, the complex features classrooms, a visitor center, a community building and a "tree house," all sustainably built. The City of Bellevue and Pacific Science Center offer year-round education about wetlands and nature for adults, youth and families at the center.

  • Art in Nature - Local artists display their art inside the Visitor Center.  Exhibits are curated by the Eastside Association of Fine Arts.

Visitor Center Hours and Information

The visitor center, open daily from 10 a.m. to 4 p.m., has interpretive displays depicting the nature park’s history and wildlife and plants often seen within the park. There is also an interactive library for all ages, including children’s books and adult field guides. The Artist’s Nook features a different artist each month. These pieces range in style and composition, with the underlying theme of being inspired by nature. The spacious community building is a place where everyone can gather for environmental programs, community gatherings or rental events.

Visitors to MSEEC can view the slough, surrounding wetlands, and wildlife from the tree house, elevated boardwalk systems, and the many viewing overlooks. Stop by the Visitor Center to pick up a trail map of the nature park, program information and see the interpretive display and this month’s artist.


The MSEEC is a collaboration between the City of Bellevue and the Pacific Science Center.  This partnership brings year-round education and interpretation of freshwater ecosystems, wetland ecology, environmental stewardship and the effect of urban development to adults, youth and families.  MSEEC is the keystone of interpretive facilities and programs for the City of Bellevue and serves as the Eastside focal point for the Pacific Science Center.  The MSEEC provides classrooms for environmental education, a visitor center for interpretation and a community building for rentals, community gatherings and environmental programs.

Green Building Features

The MSEEC was designed and built to have minimal impact on the environment. Special gutters, porous concrete and catchment ponds slow and filter water runoff at the site. Green roofs reduce impermeable surfaces and warming around buildings. Renewable, recycled, local materials, along with sustainably harvested wood were used in the construction of the buildings.

The city has received a gold LEED (Leadership in Energy and Environmental Design) rating. LEED is a third-party certification program developed by the U.S. Green Building Council and is the nationally accepted benchmark for the design, construction and operation of high-performance green buildings.
