Connected with nature, our lives are better

We are healthier and happier, and our communities are stronger, more equitable, and more economically competitive. Enhancing people’s connections to nature drives our mission.

The Mountains to Sound Greenway Trust is a coalition-based organization that leads and inspires action to conserve and enhance this special landscape, ensuring a long-term balance between people and nature.
