Mission
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.

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.
