The Mountains to Sound Greenway encompasses over 1.5 million acres of connected natural lands and vibrant urban areas surrounding I-90 between Puget Sound and Central Washington. The Greenway conserves a shared heritage of working farms and forests, parks, sustainable communities and abundant outdoor educational and recreational opportunities. This map illustrates that the Mountains to Sound Greenway is bounded by major watersheds, framed by the urban areas of Seattle and Ellensburg and woven together by interstate highway and an extensive network of trails that link the public to the Greenway Landscape.
