Mountains to Sound Greenway Trust


Mission Statement

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.


The Mountains to Sound Greenway encompasses connected open spaces, trails and other outdoor recreation sites, working farm and forests, and historic places and towns. Since 1991, the Greenway Trust has championed the conservation of this landscape though a broad private and public coalition, volunteer engagement, and youth education. In 2019 the Greenway became our nation’s newest National Heritage Area (NHA), joining 54 other NHA sites in 32 states designated by Congress where historic, cultural, and natural resources combine to form cohesive, nationally important landscapes.

Program Details

The Greenway’s current strategic initiatives include:
  • Supporting thriving communities by inspiring the next generation of leaders and stewards through volunteer and environmental education programs.
  • Promoting livable cities where people want to live, to attract world-class employees, and to build and sustain healthy economies.
  • Expanding the infrastructure to accommodate a dramatic increase in visitation in the Middle Fork Snoqualmie River Valley, a wilderness playground just 20 miles from Seattle.
  • Creating a united coalition of local government, community leaders, businesses, and non-profits towards the preservation of forests, farms, fish and wildlife, tourism, and recreation in the Snoqualmie Valley – an area steeped in heritage, rugged and pastoral beauty, arts, and culture.
  • Initiating and supporting collaboration in the Upper Yakima River Basin to conserve natural lands, enhance connections between communities and public lands, and engage people in education and volunteerism to care for the landscape around them.
  • Leveraging the Greenway’s new National Heritage Area designation to conserve natural resources, protect cultural heritage, and contribute to economic vitality in the region.
