Mission

Created in 1990, Mountains to Sound Greenway Trust protects and enhances a 100-mile corridor of permanent open space lands along Interstate 90 from Seattle to Central Washington. The Greenway embraces city parks and trails, wildlife habitat, working and protected forests, recreational opportunities in nature, local history, scenic beauty, tourism and educational activities that promote a balance between population growth, and a healthy environment. Since its inception, over 130,000 acres of land have been acquired by the public in the Greenway, and an additional 90,000 have been protected from development by conservation easements.
