The Mountains to Sound Greenway Trust works closely with public land management agency partners to care for and improve the extensive trail network within the Mountains to Sound Greenway National Heritage Area. Greenway Trust staff, seasonal crew members, contractors, AmeriCorps members, partners, and volunteers work together on a wide range of trail, trailhead, and recreational site maintenance and construction projects. Our primary goals are to improve recreational access, with a sharp focus on making trails safe and sustainable and helping to reduce the impacts to the natural environment from the challenges related to overuse and population growth.  

Additionally, over the past 30+ years, the Greenway Trust has assisted with the removal and decommissioning of more than 70 miles of former forest roads, many miles of which were converted to trails.
