The Mountains to Sound Greenway Trust hosts a number of different events throughout the year. From tree planting, to interpretive events, hiking, biking, and floating — there’s something for everyone! Attending an event is a great way to learn more about our mission, meet new people, and make a difference right here on the Greenway landscape. We hope to see you at one of our events soon!
