Mountains To Sound Greenway Trust

The Mountains to Sound Greenway Trust, founded in 1991, is a non-profit partnership of citizens, private landowners, businesses, public agencies, environmental organizations, and local governments working to protect and enhance the scenic I-90. The Trust supports efforts to preserve open space, farms, working forests, and historic sites, and to create new trails, recreation and tourism opportunities along the 100-mile Mountains to Sound Greenway. Trust volunteers work year-round on a variety of outdoor projects to improve the environmental health of and recreational access to the Greenway.
