About Us

The Mountains to Sound Greenway National Heritage Area is a unique geographic corridor made up of connected ecosystems and communities spanning 1.5-million-acres from Seattle to Ellensburg along the I-90 corridor. The Mountains to Sound Greenway Trust is a coalition-based organization that leads and inspires action to conserve and enhance this special landscape, ensuring a long-term balance between people and nature. Founded in 1991, the Greenway Trust works to conserve and restore natural lands, open spaces, and historic sites; build and maintain recreational trails; engage with students through our environmental education program; advocate for public lands and recreational access; lead a robust volunteer program; and so much more.
