Mountains to Sound Greenway

The Mountains to Sound Greenway spans 1.5 million acres of diverse landscapes, including forests, farms, and urban areas along Interstate 90 from Seattle to Ellensburg.

The heritage area originated in 1990 when concerned citizens hiked from Cascade Crest, leading to the establishment of the Mountains to Sound Greenway Trust in 1991.

Native American tribes, including the Colville, Muckleshoot, Snoqualmie, Tulalip, and Yakama, maintain their traditional practices of fishing and hunting within the corridor.

The Mountains to Sound Greenway includes numerous hiking trails, bicycle paths, and recreational areas connected by Interstate 90, which serves as a National Scenic Byway.

The corridor encompasses multiple watersheds, from the Yakima in the east to Puget Sound in the west, creating a connected network of natural ecosystems.
