The Trustees of Reservations preserve, for public use and enjoyment, properties of exceptional scenic, historic, and ecological value in Massachusetts. Volunteers are at the core of who we are. As a volunteer, spend an hour, a day, or make a longer commitment to volunteer with The Trustees. We can't do it without you. We enjoy and care for more than 100 special places – nearly 25,000 acres – all around Massachusetts. And we are actively building an extended family of friends and neighbors across the state that can help in their different ways. We manage and maintain over 350 miles of trails on 116 properties across Massachusetts.
