The Mountains to Sound Greenway Trust leads and inspires action to conserve and enhance the landscape from Seattle across the Cascade Mountains to Central Washington, ensuring a long-term balance between people and nature.

Our vision: an iconic 1.5 million-acre landscape that conserves a healthy and sustainable relationship between land and people by balancing built and natural environments. A landscape providing places for nature and wildlife, for outdoor recreation and education, for working forests and local agricultural production, while embracing vibrant urban areas with strong economies. A landscape supported by a broad cross-section of society, working together as an effective coalition to preserve this heritage for future generations.

Other Ways to Get Involved:

The Greenway hosts volunteer events on Saturdays year-round, which include everything from tree planting to invasive removal to trail construction! Residents in the greater Seattle area can get involved by visiting our website and registering for these public events. In addition, we love having corporate groups, businesses, youth groups, etc. contact to coordinate private events with us.
